RESUMEN
PURPOSE: To report the response of choroidal neovascularization to intravitreal ranibizumab or bevacizumab treatment in the setting of age-related macular degeneration with extensive pre-existing geographic atrophy of the retinal pigment epithelium. METHODS: This is a retrospective case series of 11 eyes in ten consecutive patients retrieved from a photographic database. The patients were treated with ranibizumab or bevacizumab for neovascular age-related macular degeneration with pre-existing geographic atrophy. Patients were included if they had geographic atrophy at or adjacent to the foveal center of at least 1 disc area in size that was present before the development of choroidal neovascularization. The best corrected visual acuity and optical coherence tomography analysis of the central macular thickness were recorded for each visit. Serial injections of ranibizumab or bevacizumab were administered until there was complete resolution of subretinal fluid on optical coherence tomography. Data over the entire follow-up period were analyzed for overall visual and optical coherence tomography changes. RESULTS: The patients received an average of 7 ± 3 intravitreal injections over the treatment period. Seven of 11 eyes had reduced retinal thickening on optical coherence tomography. On average, the central macular thickness was reduced by 72 ± 115 µm. Six of these 7 eyes had improvement of one or more lines of vision and one had no change. The average acuity change for all patients was -0.04 ± 0.46 logMAR units, which corresponded to a gain of 0.2 ± 4.4 lines of Snellen acuity. The treatment resulted in a good anatomic response with resolution of the subretinal fluid and overall stable visual acuity. CONCLUSIONS: The results of this case series suggest that the use of an intravitreal anti-vascular endothelial growth factor (VEGF) agent (ranibizumab or bevacizumab) for choroidal neovascularization in age-related macular degeneration with pre-existing geographic atrophy is effective. Our results are not as striking as published results from large-scale trials of anti-vascular endothelial growth factor therapy for subfoveal choroidal neovascularization, presumably due to the limitation in the baseline visual acuity caused by the underlying geographic atrophy. The favorable anatomic response with the resolution of subretinal fluid and stable acuity were consistent with other ranibizumab and bevacizumab studies.

PURPOSE: To report a 16-year long-term follow-up of a patient with acute multifocal hemorrhagic retinal vasculitis (Blumenkranz syndrome). A 21-year old male was seen in 1994 with acute multifocal hemorrhagic retinal vasculitis (Blumenkranz syndrome), first in the left eye, and later in the right eye. He was treated with retinal photocoagulation in areas of retinal ischemia and oral steroids, followed by sequential annual fundus examination and photography for 16 years. Vision improved to 20/25 in both eyes after retinal ischemic areas photocoagulation and oral steroids, and his vision has been maintained for 16 years. Photocoagulation of retinal ischemia and oral steroids are effective for the treatment of acute multifocal hemorrhagic retinal vasculitis (Blumenkranz syndrome).

PURPOSE: To investigate the efficacy of vascular endothelial growth factor-specific (VEGF) monoclonal antibodies in the treatment of choroidal neovascularization secondary to age-related macular degeneration (AMD) that does not extend beneath the foveal center (nonsubfoveal CNV). METHODS: The study design was a retrospective chart review of consecutive patients over a two-month period under active treatment with bevacizumab and/or ranibizumab for neovascular AMD. Patients with neovascularization within the macula that did not extend beneath the center of the foveal avascular zone, along with at least one large drusen (>125 micro) or many intermediate size (63-124 micro) drusen were included. Best corrected Snellen visual acuity and optical coherence tomography (OCT) analysis of the central macular thickness was recorded for each visit. Serial injections of bevacizumab and/or ranibizumab were administered until there was resolution of subretinal fluid clinically or by OCT. Data over the entire follow-up period were analyzed for overall visual acuity and OCT changes. All patients had follow-up since diagnosis of at least 6 months (mean=9.6 months). RESULTS: Of the thirteen included patients, eleven had reduction of retinal thickening in the area involved by the CNV. The remaining two patients did not have OCT data available but had no fluid or activity on clinical examination at last follow-up. One patient (8%) lost one line of vision; one (8%) remained stable, and eleven (84%) gained one or more lines of visual acuity. Three patients (23%) gained three or more lines. The average treatment outcome for all patients was a gain of 1.7 +/- 1.3 lines of Snellen acuity. Both therapeutic agents were effective, with an average gain of 1.6 +/- 0.6 lines for patients treated with bevacizumab, 1.5 +/- 1.9 lines gained for patients treated with ranibizumab and 2.5 +/- 0.7 lines gained in the two patients who received both agents over the course of their treatment. CONCLUSIONS: The use of intravitreal anti-VEGF agents for nonsubfoveal CNV in AMD is effective. Our results are comparable to published results from large-scale trials of anti-VEGF therapy for subfoveal CNV. Our data support the idea that bevacizumab or ranibizumab appear to be the treatment of choice for AMD patients with nonsubfoveal CNV.

OBJETIVO: Avaliação dos resultados da injeção intravítrea de ranibizumab e bevacizumab em pacientes com neovascularização de coróide da degeneração macular relacionada a idade, com atrofia geográfica extensa, pré-existente. MÉTODOS: Este é um estudo retrospectivo de 10 pacientes, 11 olhos com neovascularização de coroide da degeneração macular relacionada à idade, com atrofia geográfica extensa, pré-existente. Os pacientes incluídos apresentaram atrofia geográfica, envolvendo a fóvea ou adjacência, antes do desenvolvimento da neovascularização de coroide. A melhor correção visual e o exame de tomografia de coerência óptica com análise da espessura macular foram registrados em cada visita. As injeções de ranibizumab e bevacizumab intravítrea foram feitas até a resolução do líquido sub-retiniano pela tomografia de coerência óptica e clinicamente. Todos os pacientes tinham seguimento de 6 meses do diagnóstico a 2 anos, com média de 16 meses. RESULTADOS: Onze olhos de 10 pacientes incluídos receberam uma média de 7 ± 3 injeções intravítreas de ranibizumab e bevacizumab, sendo que 7 apresentaram redução do espessamento macular pelo tomografia de coerência óptica. A mácula teve o espessamento reduzido entre 72 ± 115 µm, 6 olhos tiveram melhora de 1 ou mais linhas de visão, um olho teve acentuada diminuição da visão e um outro não teve alteração. A média do resultado do tratamento em logMAR era -0,04 ± 0,46 correlacionando um ganho de visão na tabela de Snellen entre 0,2 ± 4,4 linhas de visão. CONCLUSÕES: Estes resultados sugerem que o uso do ranibizumab e bevacizumab intravítrea para neovascularização de coroide da degeneração macular relacionada à idade em extensa atrofia geográfica pré-existente é eficaz. Há, entretanto dificuldades na avaliação da acuidade visual destes pacientes em virtude da extensa atrofia geográfica que apresentavam e sobre esta ainda a neovascularização de coroide, se comparados a casos em que a neovascularização de coroide não ocorre em atrofia geográfica pré-existente.

A degeneração macular relacionada à idade (DMRI) é uma doença degenerativa da área central da retina freqüentemente associada à perda visual central, em pessoas acima de 55 anos de ambos os sexos, sendo a mais importante causa de cegueira irreversível em adultos nos países desenvolvidos e a terceira causa de cegueira no mundo. OBJETIVO: Avaliar a eficácia da injeção intravítrea de Ranibizumab (anti-VEGF) no tratamento da neovascularização de coróide não subfoveal, podendo ser extrafoveal ou justafoveal, causada pela degeneração macular relacionada à idade exsudativa e revisão da literatura. MÉTODOS: Foi realizado um estudo descritivo e transversal com avaliação de quinze pacientes com neovascularização de coróide extrafoveal ou justafoveal causada por degeneração macular relacionada à idade. Os pacientes foram tratados com uma injeção intravítrea, por mês, no mínimo por três meses consecutivos, de Ranibizumab na dose de 0,5mg, no olho com neovascularização de coróide. Os mesmos foram examinados com um mês de intervalo entre as aplicações das injeções e acompanhados com exames complementares. RESULTADOS: Os resultados da análise dos quinze pacientes que foram incluídos nesta série de casos mostraram que onze (73,3 por cento) pacientes apresentavam neovascularização de coróide extrafoveal e quatro (26,6 por cento) justafoveal. Oito (53,3 por cento) apresentavam a forma oculta e sete (46,6 por cento) tinham lesões clássicas. A média de injeções realizadas foi de 3,67, sendo o menor número de injeções 3 e o maior 6 injeções. Oito (53,3 por cento) pacientes apresentaram resolução do quadro exsudativo neovascular com o máximo de três injeções e apenas um (6,67 por cento) paciente necessitou de seis injeções para resolução do seu quadro. A acuidade visual máxima alcançada foi de 20/30, e ocorreu em cinco (33,3 por cento) pacientes. A média de acuidade visual no momento do diagnóstico foi de 0,44logMAR e a média final de 0,27logMAR Na avaliação final dos pacientes após os seis meses de estudo, a média de linha de visão ganha foi de 1,87 linha de acuidade visual pela tabela de Snellen, sendo que todos os 15 pacientes ganharam uma ou mais linhas de visão. CONCLUSÃO: No tratamento dos pacientes com degeneração macular relacionada à idade e neovascularização de coróide extrafoveal a injeção de Ranibizumab mostrou-se eficaz, podendo ser a opção como indicação inicial de tratamento nestes casos.
Age-related macular degeneration is a major cause of central vision loss and is the leading cause of blindness for people aged over 60 years. PURPOSE: To investigate the efficacy of intravitreal injection of Ranibizumab (anti-VEGF) in the treatment of choroidal neovascularization nonsubfoveal, extra-foveal or juxta-foveal, caused by age-related macular degeneration and revision paper. METHODS: The study design was descriptive and transverse.15 patients with nonsubfoveal choroidal neovascularization caused by age-related macular degeneration, were treated with intravitreal injection of Ranibzumab per month, at least for three consecutive months. Patients were examined at one month interval between the injections and evaluated using visual acuity testing with Snellen charts, fluorescein angiography, and optical coherence tomography scans. RESULTS: There were 11extra-foveal lesions (73.3 percent) and 4 juxta-foveal lesions (26.6 percent). Seven lesions were predominantly classic (46.6 percent) and eight lesions were occult (53,3 percent). The mean number of injections performed was 3.67 and the lowest number of injections 3 and 6 larger injections. Eight (53.3 percent) patients had complete resolution of the exudative neovascular condition with a maximum of three injections and only one (6.67 percent) patient required six injections to resolution his condition. The best visual acuity achieved was 20/30, and occurred in five (33.3 percent) patients. The mean visual acuity at diagnosis was 0.44 logMAR and 0.27 logMAR final average. In the final evaluation of patients after six months of study, the average line of sight gains were 1.87 line of visual acuity by Snellen chart. All 15 patients gained one or more lines of vision. CONCLUSION: In the treatment of patients with nonsubfoveal choroidal neovascularization in age-related macular degeneration, injection of Ranibizumab was effective and could be an option as an indication of initial treatment in these cases.

PURPOSE: To report a polypoidal vascular choroidopathy clinical case causing cystoid macular edema and the response to Ranibizumab intravitreal treatment. METHODS: A 62-year old caucasian woman was referred by her comprehensive ophthalmologist for retinal avaliation. On presentation best corrected visual acuity was 20/100 in the left eye and 20/20 in right eye.Anterior segment examination was unremarkable in both eyes. Clinical examination and FA on the left eye demonstrated numerous small drusen and a cystoid macular edema due leakage from any polips in justapapilar region and from polips in the superior arcade vascular region and subretinal fluid and cystic change in the OCT.The right eye had FA normal. The patient refused to submitt a ICGV angiography. The patient was treated by intravitreal ranibizumab injections in the left eye every 4 weeks, 3 injections ,three months. RESULTS: The patient showed resolution both of cystic change and subretinal fluid in the OCT, and the visual acuity in the six months follow-up improved to 20/25. The patient was followed by 18 months at this time and the visual acuity remained stable 20/25. CONCLUSION: We reported a patient case of cystoid macular edema from a polypoidal choroidal vaculopathy that responded well to ranibizumab intravitreal injection as monotheraphy with disappearance of the initial subretinal fluid and cystic change in OCT follow-up and stop the polips.
OBJETIVO: Relatar um caso de paciente com Vasculopatia coroidiana polipoidal com edema macular cistóide e a resposta ao tratamento com Ranibizumab intravítrea como monoterapia MÉTODOS: Uma paciente com 62 anos foi referida por seu oftalmologista para avaliação retiniana . Apresentava acuidade visual com correção de 20/100 no olho esquerdo e 20/20 no olho direito. A avaliação do segmento anterior era normal em ambos os olhos. No exame de fundo de olho e retinografia fluoresceínica apresentava numerosas drussas pequenas e edema macular cistóide devido a vazamentos de alguns pólipos vasculares coroidianos na arcada vascular superior e ainda fluido sub-retiniano e alteração cística no OCT . O olho direito apresentava angiografia fluoresceínica da retina e OCT normais.A paciente recusou-se a se submeter a vídeoangiografia com indocianina verde. A paciente foi tratada com injeção intravítrea de Ranibizumab como monoterapia, sendo uma injeção a cada quatro semanas, três injeções em três meses. RESULTADOS: A paciente apresentou resolução da alteração cística e do fluido sub-retiniano, ambos presentes no OCT prévio ao tratamento no olho esquerdo. A acuidade visual melhorou para 20/25 após 6 meses de tratamento. A paciente permanence com acuidade visual estável de 20/25 após 18 meses de acompanhamento. CONCLUSÃO: Reportamos um caso de paciente com edema macular cistóide originada da vasculopatia coroidiana polipoidal que respondeu ao tratamento com Ranibizumab intravítrea, como monoterapia com desaparecimento do fluido sub-retiniano e da alteração cística no OCT tendo cessado o vazamento dos pólipos que eram a causa do edema macular cistóde.

PURPOSE: To investigate the efficacy of vascular endothelial growth factor-specific (VEGF) monoclonal antibodies in the treatment of choroidal neovascularization secondary to age-related macular degeneration (AMD) that does not extend beneath the foveal center (nonsubfoveal CNV). METHODS: The study design was a retrospective chart review of consecutive patients over a two-month period under active treatment with bevacizumab and/or ranibizumab for neovascular AMD. Patients with neovascularization within the macula that did not extend beneath the center of the foveal avascular zone, along with at least one large drusen (>125 µ) or many intermediate size (63-124 µ) drusen were included. Best corrected Snellen visual acuity and optical coherence tomography (OCT) analysis of the central macular thickness was recorded for each visit. Serial injections of bevacizumab and/or ranibizumab were administered until there was resolution of subretinal fluid clinically or by OCT. Data over the entire follow-up period were analyzed for overall visual acuity and OCT changes. All patients had follow-up since diagnosis of at least 6 months (mean=9.6 months). RESULTS: Of the thirteen included patients, eleven had reduction of retinal thickening in the area involved by the CNV. The remaining two patients did not have OCT data available but had no fluid or activity on clinical examination at last follow-up. One patient (8 percent) lost one line of vision; one (8 percent) remained stable, and eleven (84 percent) gained one or more lines of visual acuity. Three patients (23 percent) gained three or more lines. The average treatment outcome for all patients was a gain of 1.7 ± 1.3 lines of Snellen acuity. Both therapeutic agents were effective, with an average gain of 1.6 ± 0.6 lines for patients treated with bevacizumab, 1.5 ± 1.9 lines gained for patients treated with ranibizumab and 2.5 ± 0.7 lines gained in the two patients who received both agents over the ...
OBJETIVO: Investigar a eficácia dos anti-angiogênicos ranibizumab e bevacizumab injetados intravítreo, no tratamento de pacientes com neovascularização de coróide extrafoveal em degeneração macular relacionada à idade. MÉTODOS: Foram avaliados 13 pacientes com neovascularização de coróide extrafoveal em degeneração macular relacionada à idade do Setor de Retina e Vítreo do Departamento de Oftalmologia da Universidade de Iowa, Estados Unidos, que foram tratados por meio de injeção vítrea de ranibizumab e bevacizumab separadamente, em um período de dois anos. Após as injeções iniciais os pacientes foram acompanhados por exames de OCT e as injeções foram repetidas com 4 a 8 semanas dependendo da presença de líquido sub-retiniano e macular. RESULTADOS: Doze pacientes tiveram ganhos de linhas de visão se comparados com a visão antes do tratamento. Onze pacientes tiveram redução do espessamento retiniano na área envolvida pelo CNV e diminuição e resolução do espessamento macular na sua visita final de avaliação. Um paciente (8 por cento) perdeu uma linha de visão se comparado à visão prévia ao tratamento. Pacientes tratados com o ranibizumab tiveram em média 2,5 ± 0,7 ganhos de linhas de visão. Pacientes tratados com bevacizumab tiveram em média 1,6 ± ganhos de linhas de visão. CONCLUSÃO: No tratamento de pacientes com a neovascularização de coróide extrafoveal em degeneração macular relacionada à idade, a injeção vítrea de ranibizumab ou bevacizumab é efetiva e pode ser a opção de escolha.
