ABSTRACT Purpose: To evaluate the effectiveness of intravitreal aflibercept treatment for macular edema with and without serous retinal detachment due to branch retinal vein occlusion. Methods: Thirty-seven eyes with branch retinal vein occlusion treated with intravitreal aflibercept injection for macular edema were evaluated retrospectively. The patients were divided into two groups according to whether they showed serous retinal detachment on spectral domain optical coherence tomography. Pro re nata regimen was applied after 1 dose of intravitreal aflibercept injection. After the initial injection, control treatments were administered at months 1, 2, 3, 6, and 12. The best-corrected visual acuity and central macular thickness were measured. Results: Fifteen patients had serous retinal detachment, and 22 with macular edema only (non-serous retinal detachment). The central macular thickness was significantly greater in the group with than in the group without serous retinal detachment (811.73 ± 220.68 µm and 667.90 ± 220.68 µm, respectively, p=0.04). The difference between the groups disappeared from the third month. The central macular thickness was similar between the two groups at the last control treatment (407.27 ± 99.08 µm and 376.66 ± 74.71 µm, p=0.66). The best-corrected visual acuity increased significantly in both groups. No significant difference was found between the two groups in terms of the best-corrected visual acuities at baseline and the final control. Conclusion: The intravitreal aflibercept treatment was highly effective in improving best-corrected visual acuity and central macular thickness in patients with branch retinal vein occlusion-induced macular edema independent of serous retinal detachment.
RESUMO Objetivo: Avaliar a eficácia do tratamento com aflibercepte intravítreo para edema macular devido à oclusão de um ramo da veia retiniana, com e sem descolamento seroso da retina. Métodos: Foram analisados retrospectivamente 37 olhos com oclusão de um ramo da veia retiniana, tratados com injeção intravítrea de aflibercepte para edema macular. Os pacientes foram divididos em dois grupos, de acordo com a presença ou ausência de um descolamento seroso de retina na tomografia de coerência óptica (SD-OCT). Um regime pro re nata foi seguido após 1 injeção intravítrea de aflibercepte. Após a injeção, foram realizadas consultas de acompanhamento nos meses 1, 2, 3, 6 e 12. Foram medidas a melhor acuidade visual corrigida e a espessura macular central. Resultados: Houve 15 pacientes com descolamento seroso de retina e 22 pacientes com apenas edema macular (descolamento não seroso de retina). A espessura macular central foi significativamente maior no grupo com descolamento seroso de retina do que no grupo com descolamento não seroso de retina (respectivamente, 811,73 ± 220,68 µm e 667,90 ± 220,68 µm; p=0,04). A diferença desapareceu a partir do terceiro mês. A espessura macular central foi semelhante nos dois grupos na última consulta (407,27 ± 99,08 µm e 376,66 ± 74,71 µm, p=0,66). A melhor acuidade visual corrigida aumentou significativamente em ambos os grupos. Não houve diferença entre os dois grupos quanto à melhor acuidade visual corrigida inicial e final. Conclusão: O tratamento com aflibercepte intravítreo foi altamente eficaz em melhorar a acuidade visual corrigida e a espessura macular central no edema macular induzido pela oclusão de um ramo da veia retiniana, independentemente da presença ou não de um descolamento seroso da retina.

ABSTRACT Purpose: To investigate the effects of epiretinal membrane formation on the clinical outcomes of intravitreal dexamethasone implantation for macular edema secondary to branch retinal vein occlusion. Methods: This retrospective interventional case series includes the treatment of naive patients with macular edema secondary to non-ischemic branch retinal vein occlusion who underwent intravitreal dexamethasone implantation. The patients were divided into two groups as follows: Group 1 (n=25), comprised of patients with macular edema secondary to branch retinal vein occlusion without epiretinal membrane, and Group 2 (n=16), comprised of patients with macular edema secondary to branch retinal vein occlusion with an epiretinal membrane. Corrected visual acuity, central macular thickness, and central macular volume values were measured before and after treatment. The clinical outcomes of the groups were compared. Results: Mean age and male-to-female ratio were similar between the two groups (p>0.05, for both). The baseline and final corrected visual acuity values, central macular thickness, and central macular volumes of the groups were similar (p>0.05, for all). All the parameters were significantly improved after intravitreal dexamethasone implantation treatment (p<0.001, for all). The changes in central macular thickness and volume were also similar (p>0.05, for both). The mean number of intravitreal dexamethasone implantations was 2.1 ± 1.0 (range, 1-4) in Group 1 and 3.0 ± 1.2 (range, 1-5) in Group 2 (p=0.043). Conclusion: Epiretinal membrane formation had no effects on the baseline and final clinical parameters, including corrected visual acuity and central macular thickness and volume. The only parameter affected by the presence of epiretinal membrane formation is the number of intravitreal dexamethasone implantations, a greater number of which is needed for macular edema secondary to branch retinal vein occlusion with an epiretinal membrane.
RESUMO Objetivo: Investigar os efeitos da formação de uma membrana epirretiniana nos resultados clínicos da implantação intravítrea de dexametasona para edema macular secundário à oclusão de um ramo da veia retiniana. Métodos: Esta série retrospectiva de casos intervencionais inclui o tratamento de indivíduos com edema macular secundário à oclusão não isquêmica de um ramo da veia retiniana, sem tratamento prévio e que foram submetidos a implantação intravítrea de dexametasona. Os indivíduos foram divididos em dois grupos: Grupo 1 (n=25), composto por indivíduos com edema macular secundário à oclusão de um ramo da veia retiniana sem a presença de uma membrana epirretiniana, e Grupo 2 (n=16), composto por indivíduos com edema macular secundário à oclusão de um ramo da veia retiniana com a presença de uma membrana epirretiniana. Os valores da acuidade visual corrigida, espessura macular central e volume macular central foram obtidos antes e após o tratamento. Os resultados clínicos dos grupos foram comparados. Resultados: A média de idade e a proporção entre homens e mulheres foram semelhantes nos dois grupos (p>0,05 para ambos os valores). Os valores iniciais e finais da acuidade visual corrigida, espessura macular central e volume macular central foram semelhantes nos dois grupos (p>0,05 para todos os valores). Todos os parâmetros melhoraram significativamente após o tratamento com implante de dexametasona intravítrea (p<0,001 para todos os parâmetros) e as alterações na espessura macular central e no volume macular central também foram semelhantes (p>0,05 para ambos os valores). O número médio de implantações intravítreas de dexametasona foi 2,1 ± 1,0 (faixa de 1-4) no Grupo 1 e 3,0 ± 1,2 (faixa de 1-5) no Grupo 2 (p=0,043). Conclusão: A formação de uma membrana epirretiniana não tem efeitos sobre os parâmetros clínicos iniciais e finais, incluindo a acuidade visual corrigida, a espessura macular central e o volume macular central. O único parâmetro afetado pela formação de uma membrana epirretiniana é o número de implantações intravítreas de dexametasona, sendo necessário um número maior de implantações em casos de edema macular secundário à oclusão de um ramo da veia retiniana com a presença de uma membrana epirretiniana.

El edema macular es el engrosamiento anormal de la mácula asociado con la acumulación de líquido en el espacio extracelular de la retina neurosensorial. En algunos casos también se ha observado edema intracelular que comprende las células de Muller. Una de estas causas es el edema macular poscirugía de catarata. Presentamos un caso masculino de 57 años de edad de la raza negra con antecedentes de haber sido operado de catarata en ambos ojos. El ojo izquierdo carecía de visión a causa de un rechazo al trasplante corneal penetrante que le fue realizado. El ojo derecho presentaba edema macular con subluxación de la lente intraocular. Le realizamos biomicroscopia de segmento anterior y posterior, tomografía de coherencia óptica, agudeza visual con corrección y presión intraocular. Se constató edema macular con membrana epirretinal y subluxación de la lente intraocular. Decidimos fijar la lente a la esclera utilizando la técnica de Yamane, ya que se trataba de una lente de 3 piezas de acrílico con háptica de fluoruro de polivinildeno configuración en C (CT Lucia 602 de Zeiss), ideal para esta técnica. Colocamos una dosis de Ozurdex en el ojo derecho para tratar el edema macular, después de ver que los colirios tópicos antinflamatorios no fueron efectivos en este caso, y tuvimos una mejoría del edema por aproximadamente 3 meses. En el edema macular posquirúrgico no solo es necesario tratar la inflamación, sino también la causa que la ha producido(AU)
Macular edema is the abnormal thickening of the macula associated to fluid accumulation in the extracellular space of the neurosensory retina. Some cases also present intracellular edema with involvement of Müller cells. One of these causes is macular edema after cataract surgery. A case is presented of a male 57-year-old patient of black skin color with a history of cataract surgery in both eyes. The left eye had no vision, due to rejection to the penetrating corneal transplantation performed. The right eye presented macular edema with intraocular lens subluxation. Examination included biomicroscopy of the anterior and posterior segments, optical coherence tomography, visual acuity with correction and intraocular pressure. A diagnosis was confirmed of macular edema with epiretinal membrane and intraocular lens subluxation. It was decided to fix the lens to the sclera using the Yamane technique, since it was a three-piece lens with a C-shaped polyvinylidene fluoride haptic (CT Lucia 602 from Zeiss), ideal for this technique. An Ozurdex dose was administered in the right eye to treat the macular edema, since topical anti-inflammatory eyedrops were not effective in this case, and improvement of the edema was achieved for about three months. In postoperative macular edema, it is not only necessary to treat the inflammation, but also its cause(AU)

ABSTRACT This report aims to describe the effectiveness of a unilateral intravitreal dexamethasone implant (Ozurdex®) used for the treatment of cystoid macular edema in a patient with recurrent intermediate uveitis. Bearing in mind the adverse effects of the prolonged use of systemic corticosteroids, the objective here was to provide a less damaging form of intervention, and also to demonstrate the safety of the dexamethasone implant for patients who fail to respond to conventional treatment. In the present case, there was bilateral improvement in retinal anatomy and function with use of the unilateral intravitreal dexamethasone implant (Ozurdex®).
RESUMO Neste estudo, o objetivo foi descrever, a partir de um relato de caso, a eficácia do uso de implante de dexametasona intravítrea (Ozurdex®) unilateral, para o tratamento de edema macular cistoide, em um paciente com quadro de uveíte intermediária recorrente, visando uma terapêutica menos lesiva, diante dos efeitos colaterais do uso prolongado de corticoesteroides sistêmicos, demonstrando também a segurança desse tratamento alternativo para aqueles pacientes que se apresentam refratários a terapêutica tradicional. No caso relatado, vale ressaltar a melhora bilateral da anatomia e função retiniana com o implante unilateral de dexametasona intravítrea (Ozurdex®).

ABSTRACT Purpose: To investigate the usefulness of systemic inflammatory markers [i.e., white blood cell and platelet counts, mean platelet volume, and their ratios] as diagnostic markers of the pathogenesis of diabetic macular edema. Methods: The study cohort included 80 diabetic macular edema patients (40 with diabetic retinopathy and 40 without) and 40 healthy age- and sex-matched controls. Neutrophil, lymphocyte, monocyte, and platelet counts, and the mean platelet volume were determined from peripheral blood samples, and the monocyte/lymphocyte, platelet/lymphocyte, and mean platelet volume/lymphocyte, and neutrophil/lymphocyte ratios were calculated and compared among groups. Results: The mean neutrophil/lymphocyte ratio of the diabetic macular edema and non-diabetic macular edema groups was higher than that of the control group, and the value of the diabetic macular edema group was higher than that of the non-diabetic macular edema group (p<0.001 in diabetic macular edema vs. control, p=0.04 in non-diabetic macular edema vs. control, and p=0.03 in diabetic macular edema vs. non-diabetic macular edema). A neutrophil/lymphocyte cutoff value of ≥2.26 was identified as an indicator of the pathogenesis of diabetic macular edema with a sensitivity of 85% and specificity of 74%. The mean platelet volume of the diabetic macular edema group was higher than those of the non-diabetic macular edema and control groups, while those of the non-diabetic macular edema and control groups were similar (diabetic macular edema vs. non-diabetic macular edema, p=0.08; diabetic macular edema vs. control, p=0.02; and non- diabetic macular edema vs. control, p=0.78). All other parameters were similar between groups (all p>0.05). Conclusion: The neutrophil/lymphocyte ratio and mean platelet volume of the diabetic macular edema group were higher than those of the non-diabetic macular edema and control groups. A neutrophil/lymphocyte ratio cutoff value of ≥2.26 was identified as an indicator of the pathogenesis of diabetic macular edema with high sensitivity and specificity. Moreover, the neutrophil/ lymphocyte ratio of the non-diabetic macular edema group was higher than that of the control group.
RESUMO Objetivo: Investigar a utilidade de marcadores inflamatórios sistêmicos (ou seja, contagem de glóbulos brancos e plaquetas, volume médio de plaquetas e suas proporções) como marcadores de diagnóstico da patogênese do edema macular diabético. Métodos: A coorte do estudo incluiu 80 pacientes com edema macular diabético (40 com retinopatia diabética e 40 sem) e 40 controles saudáveis de acordo com a idade e sexo. As contagens de neutrófilos, linfócitos, monócitos, plaquetas e valores do volume plaquetário médio foram determinados a partir de amostras de sangue periféricdo, e as proporções de monócitos/linfócitos, plaquetas/linfócitos, volume plaquetário médio/linfócitos e neutrófilos/linfócitos foram calculadas e comparadas entre os grupos. Resultados: A proporção média de neutrófilos/linfócitos dos grupos com edema macular diabético e não-diabético foi maior que a do grupo controle, e o valor do grupo com edema macular diabético foi maior que o do grupo com edema macular não diabético (p<0,001 no com edema macular diabético vs. controle, p=0,04 no com edema macular não diabético vs. controle e p=0,03 no com edema macular diabético vs. o com edema macular não-diabético). Um valor de corte de neutrófilos/linfócitos ≥2,26 foi identificado como um indicador da patogênese do edema macular diabético com sensibilidade de 85% e especificidade de 74%. O volume plaquetário médio do grupo com edema macular diabético foi maior que o dos grupos com edema macular não-diabético e controle, enquanto os do grupo de edema macular não-diabético e controle foram semelhantes (edema macilar diabético vs. Edema macular não-diabético, p=0,08; com edema macular diabético vs. controle, p=0,02; e com edema macular não-diabético vs. controle, p=0,78). Todos os outros parâmetros foram semelhantes entre os grupos (todos p>0,05). Conclusão: A proporção de neutrófilos/linfócitos e o volume plaquetário médio do grupo com edema macular diabético foram superiores aos do grupo com edema macular não-diabético e controle. Um valor de corte da razão neutrófilos/linfócitos ≥2,26 foi identificado como um indicador da patogênese do edema macular diabético com alta sensibilidade e especificidade. Além disso, a proporção de neutrófilos/linfócitos do grupo com edema macular não-diabético foi superior à do grupo controle.

ABSTRACT Purpose: To investigate retinal microvasculature changes in patients treated with anti-VEGF for macular edema secondary to branch retinal vein occlusion. Methods: We examined 38 eyes of 19 patients for the study. We measured superficial and deep capillary plexus vessel densities (%), foveal avascular zone areas (mm2), and central macular thicknesses. Results: Parafoveal superficial and deep capillary plexus values were significantly lower in eyes with branch retinal vein occlusion than in fellow eyes (p<0.001). We found a significant increase in parafoveal deep capillary plexus values after the anti-VEGF treatment (p=0.032). The mean foveal avascular zone was larger in eyes with branch retinal vein occlusion than in control eyes (p<0.001). The mean central macular thickness was significantly higher in eyes with branch retinal vein occlusion than in controls, and we observed a significant decrease in central macular thickness after anti-VEGF treatment (<0.001). In addition, the cystic structures in the deep capillary plexus regressed. Conclusion: Optical coherence tomography angiography enables qualitative and quantitative evaluations during follow-up of patients treated for branch retinal vein occlusion.
RESUMO Objetivo: Investigar as alterações na microvascu latura da retina em pacientes tratados com anti-VEGF para ede ma macular secundário à oclusão de ramo da veia retiniana. Métodos: Foram examinados 38 olhos de 19 pacientes para o estudo. Medimos as densidades dos vasos do plexo capilar superficial e profunda (%), áreas da zona avascular foveal (mm2) e espessura macular central. Resultados: Os valores do plexo capilar superficial e profundo parafoveal foram significativamente menores nos olhos com oclusão de ramo da veia retiniana do que nos outros olhos (p<0,001). Encontramos um aumento significativo nos valores de plexo capilar profundo parafoveal após o tratamento com anti-VEGF (p=0,032). A zona avascular foveal média foi maior nos olhos com oclusão de ramo da veia retiniana do que nos olhos controle (p<0,001). A espessura macular central média foi significativamente maior nos olhos com oclusão de ramo da veia retiniana do que nos controles, e observamos uma diminuição significativa na espessura macular central após o tratamento com anti-VEGF (< 0,001). Além disso, as estruturas císticas no plexo capilar profundo regrediram. Conclusão: A angiotomografia de coerência óptica permite avaliações qualitativas e quantitativas durante o acompanhamento de pacientes tratados por oclusão de ramo da veia retiniana.

ABSTRACT Purpose: To evaluate the rate of cystoid macular edema development among cataract surgery patients on four different therapeutic regimens. Methods: The present study is a retrospective analysis of 5,380 eyes following uncomplicated phacoemulsification at Wake Forest University. The study period went from July 2007 to December 2012. Patients received one of four regimens, as follows: postoperative generic ketorolac 0.4% and prednisolone 1%, postoperative name-brand ketorolac 0.45% and prednisolone 1%, postoperative bromfenac 0.09% and prednisolone 1%, preoperative and postoperative bromfenac 0.09% alone. A statistical analysis was performed to assess the differences in rate of cystoid macular edema development among the four different therapeutic regimens. The diagnosis of cystoid macular edema required worsening of vision and evidence of increased macular thickness on optical coherence tomography. Results: The overall rate of cystoid macular edema was 0.82%. Treatment by postoperative generic ketorolac 0.45% and prednisolone 1% demonstrated the highest rate of cystoid macular edema development (2.20% of the cases). Postoperative name-brand ketorolac 0.45% and prednisolone 1% exhibited intermediate rates of cystoid macular edema development (0.90% of the cases). Postoperative administration of bromfenac 0.09% and prednisolone 1% exhibited intermediate rates of cystoid macular edema development (0.44% of the cases). Preoperative and postoperative bromfenac 0.09% alone resulted in the lowest rate of cystoid macular edema development (0.09% of the cases). The rate of cystoid macular edema was significantly lower when bromfenac was used alone vs. either regimen where ketorolac and prednisolone were used (OR 0.043, 95% CI 0.002 to 0.312; p<0.001). Conclusions: Post-cataract surgery cystoid macular edema developed less frequently following topical non-steroidal anti-inflammatory drugs regimen compared to the other therapies evaluated. Bromfenac, without corticosteroids, achieved lower rates of cystoid macular edema vs. various combinations of non-steroidal anti-inflammatory drugs with corticosteroids.
RESUMO Objetivo: Avaliar a taxa de desenvolvimento do edema macular cistóide em pacientes submetidos à cirurgia de catarata em quatro esquemas terapêuticos diferentes. Métodos: O presente estudo é uma análise retrospectiva de 5.380 olhos após facoemulsificação não complicada na Wake Forest University. O período do estudo foi entre julho de 2007 e dezembro de 2012. Os pacientes receberam um dos quatro esquemas: cetorolaco genérico pós-operatório 0,4% e prednisolona 1%, cetorolaco 0,45% pós-operatório e prednisolona 1%, bromfenac 0,09% e a prednisolona 1% pós-operatório, bromfenaco 0,09% no pré-operatório e isoladamente no pós-operatório. Uma análise estatística foi realizada para avaliar as diferenças na taxa de desenvolvimento do edema macular cistóide entre os quatro diferentes regimes terapêuticos. O diagnóstico de edema macular cistóide exigiu uma piora da visão e uma evidência de aumento da espessura macular na tomografia de coerência óptica. Resultados: A taxa global de edema macular cistóide foi de 0,82%. O tratamento com cetorolaco genérico pós-operatório 0,45% e prednisolona 1% demonstrou a maior taxa de desenvolvimento de edema macular cistóide (2,20% dos casos). O cetorolaco 0,45% e a prednisolona 1% no pós-operatório exibiram taxas intermediárias de desenvolvimento de edema macular cistóide (0,90% dos casos). A administração de bromofenac 0,09% e de prednisolona 1% no pós-operatório apresentou taxas intermediárias de desenvolvimento de edema macular cistóide (0,44% dos casos). O bromfenac 0,09% no pré e pós-operatório isoladamente resultou na menor taxa de desenvolvimento de edema macular cistóide (0,09% dos casos). A taxa de edema macular cistóide foi significativamente menor quando o bromfenac foi utilizado isoladamente em relação ao esquema onde cetorolaco e a prednisolona foram usados (OR 0,043, 95% CI 0,002 a 0,312; p<0,001). Conclusões: O edema macular cistóide pós-cirurgia de catarata desenvolveu-se com menor frequência após o tratamento tópico de medicamentos anti-inflamatórios não esteroidais, comparado às outras terapias avaliadas. Bromfenac, sem corticosteróides, alcançou taxas mais baixas de edema macular cistóide vs. Várias combinações em comparação com as várias combinações de drogas anti-inflamatórias não esteroidais com corticosteróides.

Introduction: Patients with diabetic macular edema can develop fundus autofluorescence alterations; thus far, these alterations have been more widely studied with scanning or confocal laser systems. Objective: To describe and classify fundus autofluorescence abnormal patterns in patients with diabetic macular edema using the fundus autofluorescence system with a flash camera. Method: Observational, retrospective, cross-sectional, descriptive study. Fundus autofluorescence digital images of non-comparative cases with untreated diabetic macular edema, obtained and stored with a flash camera system, were assessed. Inter-observer variability was evaluated. Results: 37 eyes of 20 patients were included. Lens opacity was the most common cause of inadequate image quality. Five different fundus autofluorescence patterns were observed: decreased (13%), normal (40%), single-spot hyper-autofluorescent (17 %), multiple-spot hyper-autofluorescent (22 %) and plaque-like hyper-autofluorescent (8 %). The kappa coefficient was 0.906 (p = 0.000). Conclusions: Different fundus autofluorescence phenotypic patterns are observed with flash camera systems in patients with diabetic macular edema. A more accurate phenotypic classification could help establish prognostic factors for visual loss or for the design of clinical trials for diabetic macular edema.

Abstract We herein report a patient without risk factors who presented acute bilateral Irvine-Gass syndrome after uneventful phacoemulsification. The novelty of our case lies on the fact that the patient presented acute bilateral Irvine-Gass syndrome without a predisposing systemic disease. Even though Cystoid Macular Edema (CME) was somehow expected in the first eye because of the ocular history of trauma, prophylactic measures were not strong enough to avoid its development. Furthermore, those measures could not avoid developing CME in the second eye. A 44-years-old male who underwent cataract surgery in both eyes presented bilateral Irvine-Gass syndrome. Despite prophylactic measures, both eyes developed CME after uneventful cataract surgery. Regular treatment options could not solve the situation and intravitreal Anti-VEGF injections were needed. Bilateral cases of Irvine-Gass Syndrome are rare and generally associated with systemic risk factors. Patients who developed CME following their first cataract surgery should be counseled about the risks of developing the condition following surgery on the contralateral eye. On top of that, aggressive prophylactic measures should be encouraged to prevent CME in these cases.
Resumo Relatamos aqui um paciente sem fatores de risco que apresentou síndrome de Irvine-Gass bilateral aguda após facoemulsificação sem intercorrências. A novidade do nosso caso reside no fato de o paciente apresentar síndrome de Irvine-Gass bilateral aguda sem doença sistêmica predisponente. Embora o Edema Macular Cistoide (EMC) fosse de alguma forma esperado no primeiro olho por causa do histórico ocular de trauma, as medidas profiláticas não foram suficientemente fortes para evitar seu desenvolvimento. Além disso, essas medidas não puderam evitar o desenvolvimento de EMC no segundo olho. Homem de 44 anos submetido a cirurgia de catarata em ambos os olhos apresentou síndrome de Irvine-Gass bilateral. Apesar das medidas profiláticas, ambos os olhos desenvolveram EMC após a cirurgia de catarata sem intercorrências. As opções de tratamento regular não conseguiram resolver a situação e foram necessárias injeções intravítreas de Anti-VEGF. Casos de Síndrome de Irvine-Gass bilateral são raros e geralmente associados a fatores de risco sistêmicos. Os pacientes que desenvolveram EMC após a primeira cirurgia de catarata devem ser avisados sobre os riscos de desenvolver a doença após a cirurgia no olho contralateral. Além disso, medidas profiláticas agressivas devem ser incentivadas para evitar a EMC nesses casos.

INTRODUCCIÓN El edema macular es una complicación frecuente de la oclusión de la vena central de la retina que clínicamente provoca deterioro de la agudeza visual. Los tratamientos más utilizados son el implante de dexametasona y los fármacos anti factor del crecimiento endotelial vascular, destacando aflibercept dentro de estos. Sin embargo, no existe consenso acerca de qué tratamiento constituye la mejor alternativa. MÉTODOS Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un meta análisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES Identificamos dos revisiones sistemáticas que en conjunto incluyeron cuatro estudios primarios, todos ensayos aleatorizados. Concluimos que no es posible establecer si aflibercept es superior a dexametasona en términos de mejora de agudeza visual y seguridad, debido a que la certeza de la evidencia existente ha sido evaluada como muy baja.
INTRODUCTION Macular edema is a frequent complication of central retinal vein occlusion that might lead to deterioration of visual acuity. The most commonly used treatments are dexamethasone implant and anti-vascular endothelial growth factor drugs, being aflibercept one of the most commonly used them. However, there is no consensus about which treatment constitute the best alternative. METHODS We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS We identified two systematic reviews that included four primary studies overall, all randomized trials. We concluded that it is not possible to establish whether aflibercept is superior to dexamethasone in terms of improvement of visual acuity and safety, because the certainty of the existing evidence has been evaluated as very low.

ABSTRACT Purpose: To evaluate the response to sub-Tenon's triamcinolone injection in patients with uveitis. Methods: We studied 28 eyes with macular edema associated with controlled uveitis. We administered sub-Tenon's injection of triamcinolone and followed the patients for 180 days to analyze the positive effects (improvement of macular edema and visual acuity) and monitor the possible adverse effects. This prospective study was conducted at the Department of Ophthalmology, Hospital de Clínicas de Porto Alegre, Brazil. Results: We observed improvement in macular edema in 86% of patients. The mean central macular thickness at each time point of assessment was 432.22, 298.80, 286.37, 267.49, 253.87, and 253.49 mm at baseline (before sub-Tenon's injection of triamcinolone), 15 days after the procedure, at 30 days, at 60 days, at 90 days, and at 180 days, respectively. The mean reduction in retinal thickness was 30.8%, 33.7%, 38.11%, 41.2%, and 41.35% at 15, 30, 60, 90, and 180 days of follow-up, respectively. Visual acuity also improved in 85.7% of patients, with a mean improvement of 1.36, 1.93, 2.23, 2.26, and 2.30 lines gained on the Early Treatment Diabetic Retinopathy Study chart at 15, 30, 60, 90, and 180 days of follow-up, respectively. No statistically significant increases in intraocular pressure and conjunctival abnormalities were caused by the procedure, and no other adverse effects were observed. Overall, the results of this study were similar to those described in the literature. Conclusions: Sub-Tenon's injection of triamcinolone provides reduced macular thickness and improvement in visual acuity with no significant adverse effects and is therefore an effective and safe procedure for the treatment of sequelae of uveitis.
RESUMO Objetivos: Avaliar os efeitos da injeção subtenoniana de triancinolona em pacientes com uveítes. Métodos: Foram incluídos na avaliação 28 olhos com edema macular associado à uveíte. Esses pacientes foram submetidos à injeção subtenoniana de triancinolona e acompanhados ao longo de 180 dias, para analisar os efeitos em relação à melhora do edema macular, da acuidade visual e acompanhamento de possíveis efeitos adversos. Trata-se de um estudo prospectivo, realizado no Serviço de Oftalmologia do Hospital de Clínicas de Porto Alegre. Resultados: Foi verificada melhora do edema macular em 86% dos pacientes, sendo uma redução média da espessura retiniana de 30,8% aos 15 dias, 33,7% aos 30 dias, 38,11% aos 60 dias, 41,2% aos 90 dias e 41,35% aos 180 dias de seguimento. Também foi observado melhora da acuidade visual em 85,7% dos pacientes e ganho de linhas na tabela de acuidade visual, sendo 1,36 linhas aos 15 dias de seguimento, 1,93 linhas aos 30 dias, 2,23 linhas aos 60 dias, 2,26 linhas aos 90 dias e 2,30 linhas aos 180 dias. Não houve significância estatística em relação ao aumento da pressão intraocular e às alterações conjuntivais causadas pelo procedimento, sem detecção de qualquer outro efeito colateral. Foi concluído que os resultados encontrados nesse estudo são similares aos descritos na literatura. Conclusões: A injeção subtenoniana de triancinolona é um procedimento eficaz e seguro para o tratamento das sequelas por quadros de uveítes, proporcionando redução da espessura macular e melhora da acuidade visual, sem relação com efeitos adversos significativos.

Resumo Objetivo: Investigar fatores prognósticos a curto prazo em pacientes portadores de edema macular diabético (EMD) tratados com injeções intravítreas (IV) de ranibizumabe (RZB). Métodos: Estudo descritivo transversal, retrospectivo, analisou-se 41 prontuários de uma clínica privada na cidade de Belo Horizonte - Minas Gerais, do período de agosto de 2016 a maio de 2017. Verificou-se dados gerais e história pregressa de pacientes que receberam IV mensais consecutivas para EMD, investigando-se sexo, idade e presença de tratamento prévio como possíveis fatores prognósticos determinantes nas mudanças na acuidade visual após o procedimento mensal. Resultados: No total da amostra, 51,2% eram indivíduos do sexo feminino. A média de idade foi de 64,20 ± 7,54 anos. Não houve associação estatisticamente significativa entre idade, gênero ou realização de tratamento prévio e melhora na acuidade visual. Conclusão: A principal estratégia de tratamento para o EMD estabelecida atualmente é através das injeções IV que apresentam eficácia comprovada na melhora da acuidade visual. Entretanto, aproximadamente metade dos pacientes não exibem resposta completa ou são refratários a essa abordagem terapêutica. Nesse sentido, o reconhecimento de fatores prognósticos pode ajudar os oftalmologistas a tomar decisões mais individualizadas, decidindo quais pacientes com EMD responderá às terapias anti-VEGF. Tendo em vista que não há estudos para averiguar os efeitos a curto prazo após injeções IV, no contexto apenas dessa melhora visual, esse trabalho se propôs a avaliar os possíveis fatores prognósticos, que se refletem em uma melhor resposta ao tratamento anti-VEGF, a partir da análise da melhor acuidade visual corrigida, em um contexto real da prática oftalmológica.
Abstract Purpose: Study the prognostic factors for short-term visual improvement in pacients treated with ranibizumab (IVR) for diabetic macular edema (DME). Methods: cross-sectional descriptive study in which 41 eletronic medical records of patients who attended in a private medical clinic in Belo Horizonte - Minas Gerais in a period of August / 2016 to May / 2017. It was verified general data and previous history of patients who received consecutive monthly IVR for DME, analyzing sex, age and presence of previous treatment as possible prognostic factors determining the changes in visual acuity measured by the Snellen table after the monthly procedure. Results: In the total sample, 51.2% were female subjects. The mean age was 64.20 ± 7.54 years. Age, previous treatment and gender were not correlated with better visual acuity in any time. Conclusion: The major strategy of DME treatment nowadays is intravitreal injections, which have proved to be an effetive way of visual acuity improvement. However, many patients do not exhibit the expected outcome or are refractory to treatment. Aiming to predict the treatment efficacy in short term - also to provide the patient a reasonable expectation about the outcome - based on prognostic factors, new clinical studies are necessary since there are so few that approach this subject - such an important treatment of a very prevalent disease.

El micropulso es una tecnología láser que consiste en proporcionar solo una fracción de la energía usualmente utilizada para la realización del efecto deseado. La eficacia clínica del láser 577 nm ha mostrado una respuesta terapéutica favorable con mínimos daños colaterales tanto en los tratamientos convencionales de onda continua como en modo micropulsado para algunas enfermedades maculares, como edema macular diabético, retinopatía serosa central y oclusión venosa retiniana. IQ577TM ofrece, además, la tecnología TxCell, la que permite el uso de patrones con múltiples spots, aumenta la eficiencia al aplicar la terapia y hace el proceso menos doloroso para el paciente. Por otra parte, tiene ventajas en el tratamiento del glaucoma, ya que la trabeculoplastia láser con micropulso no es destructiva, a diferencia de la trabeculoplastia tradicional, y permite la posibilidad de retratamientos a los pacientes que no alcanzan la presión intraocular deseada. Con el objetivo de caracterizar el láser micropulsado IRIDEX IQ577TM se realizó la presente revisión de la literatura mediante búsquedas en diferentes publicaciones relacionadas con la especialidad, para lo cual se utilizaron las bases de datos de revistas líderes de Oftalmología(AU)
Micropulse is a laser technology that consists in providing only a fraction of the energy typically used to obtain a given effect. The clinical efficacy of 577 nm laser manifests in a favorable therapeutic response with minimal collateral damage both in conventional continuous wave treatments and in micropulse mode for some macular diseases, such as diabetic macular edema, central serous retinopathy and retinal vein occlusion. IQ577TM also offers TxCell technology, which allows the use of multi-spot patterns, increasing efficiency when applying the therapy and making the process less painful for patients. On the other hand, it has advantages for the treatment of glaucoma, because, unlike traditional trabeculoplasty, micropulse laser trabeculoplasty is not destructive, making it possible to re-treat patients not achieving the desired intraocular pressure. The purpose of the study was to characterize micropulse laser IRIDEX IQ577TM. A bibliographic review was conducted based on a search in various publications related to the specialty, using the databases of leading ophthalmology journals(AU)

ABSTRACT Purpose: To analyze the effects of injections of intravitreal triamcinolone acetonide (IVTA) and intravitreal bevacizumab (IVB) on the incidence rates of anterior segment neovascularization (ASN) and neovascular glaucoma (NVG) in patients with macular edema secondary to central retinal vein occlusion (CRVO). Methods: In this prospective, randomized, double-masked, sham-controlled study, 35 patients with macular edema following CRVO were randomized to intravitreal bevacizumab, intravitreal triamcinolone acetonide, or sham injections during the first 6 months of the study. The primary outcome was the incidence rate of ASN at month 6. The secondary outcomes were the mean changes from baseline in best-corrected visual acuity (BCVA) and central foveal thickness (CFT) on optical coherence tomography over time to month 12. Results: ASN developed in 8 (22.86%) eyes, including 5 (62.50%) eyes in the sham group and 3 (37.50%) eyes in the IVTA group, during 12 months of fol low-up (p=0.009). BCVA differed significantly (p<0.05) among the groups only at month 1. CFT did not differ significantly (p<0.05) among the groups over 12 months. NVG required surgery and developed in one eye despite laser treatment. Conclusion: Early treatment with intravitreal antivascular endothelial growth factor therapy decreases the rates of ASN and NVG after CRVO.
RESUMO Objetivo: Analisar as taxas de incidência de neovascularização do segmento anterior (NSA) e de glaucoma neovascular (GNV), em pacientes com edema macular secundário a oclusão de veia central da retina (OVCR), em tratamento com injeções intravítreas de triamcinolona (IVTA) ou bevacizumab (IVB). Métodos: Neste estudo prospectivo, randomizado, duplo mascarado e sham controlado, 35 pacientes com edema macular secundário a OVCR foram randomizados para IVB, IVTA ou para o grupo controle (sham), durante os 6 primeiros meses do estudo. O desfecho primário foi a taxa de incidência de NSA no mês 6. Os desfechos secundários foram alterações médias da acuidade visual corrigida (BCVA) e espessura foveal central (EFC) ao exame de tomografia de coerência óptica, até o mês 12. Resultados: NSA ocorreu em oito (22,86%) olhos, cinco (62,50%) olhos no grupo sham e três (37,50%) olhos no grupo tratado com injeções intravítreas de Triamcinolona, Não houve nenhum caso com NSA no grupo tratado com bevacizumab durante 12 meses de acompanhamento (p=0,009). A BCVA apresentou diferença estatisticamente significante (p<0,05) entre os grupos, somente no mês 1. A EFC não apresentou diferenças estatisticamente significantes (p<0,05) entre os grupos ao longo dos 12 meses. GNV ocorreu em um olho apesar do tratamento com laser e este paciente necessitou de intervenção cirúrgica. Conclusão: O tratamento precoce com injeções intravítreas de Anti VEGF podem diminuir as taxas de neovascularização do segmento anterior e glaucoma neovascular após oclusão de veia central da retina.

ABSTRACT Purpose: The aim of the present study was to evaluate visual acuity (VA) and central macular thickness (CMT) to assess the influence of serous retinal detachment (SRD) in eyes with macular edema (ME) secondary to branch retinal vein occlusion (BRVO). Methods: Sixty-one eyes with BRVO from 61 patients with ME were analyzed and divided into two groups according to the spectral domain optical coherence tomography (OCT) findings of SRD and cystoid macular edema (CME). All patients underwent complete ophthalmic examinations and OCT measurements (Cirrus, Carl Zeiss Meditec Inc, Dublin, CA). Patients with marked retinal hemorrhage, diabetic retinopathy, previous laser photocoagulation, and/or intravitreal injection were excluded. Results: The mean age of included patients (37 males, 24 females) was 65.4 ± 11.4 (53-77) years. There were 21 patients with SRD and 40 patients with CME. All of the 21 patients with SRD had CME. VA was significantly worse in the SRD group compared with the CME (non-SRD) group (0.82 ± 0.34 logMAR vs 0.64 ± 0.38 logMAR; P=0.005). Conversely, CMT was significantly greater in the SRD group than in the CME group (465 ± 115 µ vs 387 ± 85 µ; P=0.00004). Conclusion: SRD may be associated with decreased VA. The prognosis of patients with BRVO and SRD requires further investigation.
RESUMO Objetivo: O objetivo deste estudo foi investigar a acuidade visual (VA) e espessura macular central (CMT) para avaliar a influência do descolamento seroso da retina (SRD) em olhos com edema macular (ME) secundário a oclusão de ramo da veia da retina (BRVO). Método: Sessenta e um olhos de 61 pacientes com oclusão de ramo da veia da retina e edema macular foram analisados e divididos em dois grupos, de acordo com os achados na a tomografia de coerência óptica por domínio espectral (OCT), de edema macular cistóide (CME) e descolamento seroso da retina. Todos os pacientes foram submetidos a exame oftalmológico completo e exame de tomografia de coerência óptica (Cirrus, Carl Zeiss Meditec Inc, Dublin, CA). Os pacientes com hemorragia acentuada da retina, retinopatia diabética, fotocoagulação a laser e/ou injeção intravítrea prévia foram excluídos. Resultados: A idade média dos pacientes (37 homens, 24 mulheres) foi de 65,4 ± 11,4 (53-77) anos. Havia 21 pacientes com SRD e 40 pacientes com edema macular cistóide. Todos os 21 pacientes com SRD também apresentaram edema macular cistóide. VA foi significativamente pior no grupo SRD do que no grupo edema macular cistóide (non-SRD) (0,82 ± 0,34 vs 0,64 ± 0,38 logMAR, p=0,005). Por outro lado, a espessura macular central foi significativamente maior no grupo descolamento seroso da retina do que no grupo edema macular cistóide (465 ± 115 µ vs 387 ± 85 µ, p=0,00004). Conclusão: Observou-se que o descolamento seroso da retina em si pode estar relacionado à diminuição de acuidade visual. Os prognósticos dos pacientes com oclusão de ramo da veia da retina e descolamento seroso da retina precisam ser adequadamente investigados.

Objetivo: Evaluar la respuesta al tratamiento con corticoides e inmunomoduladores en niños con pars planitis. Materiales y método: Se realiza un estudio retrospectivo y observacional de nueve historias clínicas de pacientes con diagnóstico de pars planitis atendidos en el servicio de oftalmología del Hospital de Pediatría Juan P. Garrahan desde el año 2010. Resultados: De los nueve pacientes 6 eran niños y 3 niñas. El motivo de consulta principal fue disminución de la visión. La mayoría de los pacientes fueron derivados por otros oftalmólogos para tratamiento. El 100% sufrió afectación ocular bilateral. Las complicaciones fueron: catarata, queratopatía en banda, hipertensión ocular y edema macular cistoide. El 100% de los pacientes recibió tratamiento con corticoides por vía oral e inmunomoduladores. A algunos se les efectuó inyecciones de triamcinolona subtenoniana y criocoagulación. Conclusiones: con el tratamiento con prednisona e inmunomoduladores se logró mejoría en la agudeza visual en 15 ojos y 3 ojos mantuvieron igual agudeza visual. La pars planitis es una patología crónica con un pronóstico visual reservado que requiere de un seguimiento estrecho y tratamiento prolongado por parte de un equipo interdisciplinario (AU)
Objective: To assess response to steroid and immunomodulating treatment in children with pars planitis. Material and methods: A retrospective observational study was conducted reviewing nine clinical charts of children with a diagnosis of pars planitis seen at the Department of Ophthalmology of the Pediatric Hospital Juan P. Garrahan since 2010. Results: Of nine patients, six were boys and three were girls. Main complaint was loss of vision. The majority of patients were referred to our hospital by other ophthalmologists for treatment. All children had bilateral eye involvement. Complications observed were: cataracts, band keratopathy, ocular hypertension, and cystoid macular edema. All patients received oral steroids and immunomodulating treatment. In some subtenonian injection of triamcinolone and cryocoagulation was performed. Conclusions: Prednisone and immunomodulating treatment resulted in an improvement of visual acuity in 15 eyes and three eyes visual acuity remained unchanged. Pars planitis is a chronic disease with an uncertain visual prognosis that requires close follow-up and prolonged treatment by an interdisciplinary team (AU)

ABSTRACT Purpose: To evaluate the use of a slow-release dexamethasone 0.7-mg intravitreal implant for cystoid macular edema (CME) secondary to intermediate uveitis and refractory to systemic steroids. Methods: A retrospective study of the best-corrected visual acuity (BCVA), intraocular inflammation, intraocular pressure (IOP), fundus photography, optical coherence tomography (OCT), inflammation, and adverse reactions of five patients (women, mean age of 35 years) with cystoid macular edema treated with a dexamethasone implant. Patients were evaluated in seven visits until the 150th day after the implant. Results: Four patients had bilateral pars planitis and one had bilateral intermediate uveitis associated with juvenile idiopathic arthritis. Six dexamethasone devices were implanted, under topical anesthesia (one each in six eyes, five patients). The mean follow-up time was 5 months. The best-corrected visual acuity improved in all eyes that received an implant, with five having improvements of two or more lines. Optical coherence tomography showed thinning of the macula in all eyes treated, and we saw a correlation between the best-corrected visual acuity and retinal thinning. No serious adverse events occurred and no significant increase in intraocular pressure was observed. Conclusions: Slow-release dexamethasone intravitreal implants can effectively treat CME secondary to intermediate uveitis and refractory to systemic steroids. .
RESUMO Objetivos: Avaliar o implante intravítreo de liberação lenta de dexametasona 0,7 mg no tratamento do edema macular cistóide (EMC) secundário à uveíte intermediária refratária a corticosteroides orais. Métodos: Estudo retrospectivo da acuidade visual melhor corrigida, inflamação intraocular, pressão intraocular (PIO), retinografia, tomografia de coerência óptica (OCT), inflamação e reações adversas de cinco pacientes (mulheres, idade média 35 anos) com o edema macular cistóide tratado com implante de dexametasona. Pacientes foram avaliados em 7 consultas até o 150o dia pós implante. Rsultados: Quatro pacientes apresentaram parsplanite bilateral e um, uveíte intermediária bilateral associada à artrite idiopática juvenil. Seis implantes foram inseridos sob anestesia tópica.
