Diagnóstico diferencial de las reacciones inflamatorias tras uso de medicación intravítrea en degeneración macular asociada a la edad: estéril vs. infeccioso / Differential diagnosis of endophthalmitis after intravitreal drug injection for age related macular degeneration: Sterile vs. infectious

El interés por las complicaciones inflamatorias tras la inyección intravítrea de fármacos antiangiogénicos ha aumentado tras la comercialización de brolucizumab y el desarrollo de nuevas moléculas como el abicipar pegol. Dichos fármacos se asocian a una tasa de complicaciones inflamatorias mayor a los antiangiogénicos clásicos. En este contexto resulta clave el diferenciar procesos infecciosos y estériles para realizar un tratamiento efectivo y precoz. El solapamiento del cuadro clínico entre procesos infecciosos y estériles, la baja tasa de positividad en los cultivos y la heterogeneidad en la terminología son barreras para el correcto diagnóstico y reporte de las complicaciones inflamatorias tras la inyección de medicación antiangiogénica intravítrea. Los cuadros estériles comienzan de forma precoz tras la inyección, dentro de las primeras 48 h, o alrededor de 20 días después en los casos de vasculitis asociada a brolucizumab. Los procesos infecciosos comienzan como promedio en el tercer día tras la inyección, y hasta una semana después de la misma. La disminución grave de la agudeza visual, el dolor severo, la hiperemia severa, el hipopion y un mayor grado de inflamación intraocular deben orientar hacia procesos infecciosos. En los casos en que exista duda sobre la etiología de la inflamación, debe procederse a un control muy estrecho del paciente o al tratamiento antimicrobiano empírico junto con la toma de muestra para evitar complicaciones derivadas de una endoftalmitis infecciosa. Por el contrario, los fenómenos estériles deben ser tratados con observación en los casos más leves o corticoterapia adaptada a la gravedad de inflamación en los casos más graves (AU)

The recent release of brolucizumab and the development of new antiangiogenic molecules as abicipar pegol has increased the interest towards inflammatory complications after intravitreal drug injection. Those drugs are associated to a higher rate of inflammatory adverse events compared to classic drugs. In this context it is essential to differentiate between sterile and infectious cases for a fast and effective treatment. The clinical similarities between infectious and sterile cases, the high rate of culture negative patients and the heterogeneity in the terminology used are obstacles for a correct diagnosis and report of these complications. Sterile cases appear early after the injection, before 48h; or 20 days after in brolucizumab-related vasculitis cases. Infectious cases show up around the third day after injection and up to a week after it. A severe visual impairment, severe pain, severe hyperemia, hypopyon and a more severe intraocular inflammatory process are signs of a likely infectious origin. If the cause of the inflammation is uncertain we must follow up the patient closely or “tap and inject” antimicrobial agents in order to prevent the eventual complications of an infectious endophthalmitis. On the other hand, sterile endophthalmitis might be observed in mild cases or treated with steroids according to the severity of the inflammation (AU)

Evaluación de signos tomográficos no exudativos en casos de degeneración macular asociada a la edad de tipo exudativo / Evaluation of non-exudative tomographic signs in cases of exudative age-related macular degeneration

Objetivo Analizar la prevalencia de signos tomográficos no exudativos (signo de cebolla, seudoedema, tubulación de la retina externa, seudoquistes, hendiduras subretinianas y atrofia macular) en pacientes con degeneración macular asociada a la edad neovascular. Material y métodos Un total de 174 ojos de pacientes con degeneración macular asociada a la edad neovascular que no habían recibido tratamiento previo fueron incluidos en el estudio. Se valoró la agudeza visual, la actividad de la neovascularización y la aparición o no de los distintos signos objeto de estudio en los tiempos 0 (visita inicial), 4 meses, un año, año y medio y a los 2 y 3 años de seguimiento. Se evaluaron también: la edad, el sexo, el ojo afecto y el tipo de neovascularización (1, 2, 3, polipoidea o mixta). Los análisis se han realizado mediante el software estadístico R (versión 3.3.2) y el paquete glmmADMB (versión 0.8.3.3). Resultados La presencia de seudoquistes y tubulación de la retina externa va en aumento a lo largo del seguimiento. El signo de cebolla comienza con una frecuencia ascendente hasta los 12 meses, posteriormente desciende a los 18 meses y vuelve a incrementarse a los 24 meses. En cuanto al seudoedema, mantiene un incremento hasta los 18 meses para finalmente descender. Las hendiduras subretinianas son el signo más raro, presentándose en el 1,1% en la primera visita. Finalmente, la atrofia macular, presente en el 12,6% de los ojos inicialmente, se encuentra en el 25% a los 2 años. Conclusión Los seudoquistes, la tubulación de la retina externa y la atrofia macular fueron los signos más prevalentes, mientras que las hendiduras subretinianas fueron los más infrecuentes (AU)

Objective To analyze the prevalence of non-exudative tomographic signs (onion sign, pseudoswelling, external retinal tubulation, pseudocysts, subretinal clefts and macular atrophy) in patients with neovascular age-related macular degeneration. Material and methods A total of 174 eyes of patients with neovascular age-related macular degeneration who had not received previous treatment were included in the study. Visual acuity, neovascularization activity, and the appearance or not of the different signs under study were assessed at times 0 (initial visit), 4 months, one year, year and a half, and at 2 and 3 years of follow-up. The following were also evaluated: age, sex, affected eye and type of neovascularization (1, 2, 3, polypoid or mixed). The analysis were performed using the statistical software R (version 3.3.2) and the glmmADMB package (version 0.8.3.3). Results The presence of pseudocysts and external retinal tubulation increases throughout the follow-up. The onion sign begins with an ascending frequency up to 12 months, then decreases at 18 months and increases again at 24 months. Regarding pseudowelling, it maintains an increase until 18 months to finally decrease. Subretinal clefts is the rarest sign, presenting in 1.1% on the first visit. Finally, macular atrophy, present in 12.6% of the eyes initially, is found in 25% after 2 years. Conclusion Pseudocysts, external retinal tubulation and macular atrophy were the most prevalent signs, while subretinal clefts were the most infrequent (AU)

OBJETIVO: Analizar la incidencia y los resultados visuales de cada uno de los subtipos de lesión neovascular en pacientes con degeneración macular asociada la edad (DMAE). MATERIAL Y MÉTODOS: Revisión retrospectiva de pacientes con DMAE neovascular tratados en el Hospital Universitario y Politécnico la Fe de Valencia por un mismo retinólogo (RGP) desde diciembre de 2012 hasta julio del 2015. Se registraron las formas anatómicas del complejo neovascular, así como el número de tratamientos intravítreos administrados y el cambio de visión obtenido con este. RESULTADOS: Fueron incluidos 174 ojos de 156 pacientes con una edad media de 79,9 años y un seguimiento de al menos 4 meses. El 40,8% presentaban neovascularización coroidea (NVC) tipo 1; el 12%, tipo 2; el 31%, tipo 3; el 14,4% presentaban formas mixtas y el 1,7%, vasculopatía polipoidea. La agudeza visual inicial media era de 0,32 y de 0,38 a los 24 meses, habiendo recibido una media de 9,3 inyecciones. Las formas neovasculares tipo 2, 3 y mixtas mostraron un resultado visual significativamente inferior a las tipo 1, no existiendo significación estadística en la vasculopatía polipoidea. CONCLUSIONES: La NVC tipo1 fue la más observada, y además se relacionó con un mejor pronóstico visual, en comparación con el resto de lesiones neovasculares, en pacientes tratados con ranibizumab

OBJECTIVE: To analyse the incidence and outcomes of the different neovascular subtypes in age-related macular degeneration (AMD). MATERIAL AND METHODS: A retrospective review was carried out on patients with neovascular AMD treated in the University and Polytechnic Hospital la Fe in Valencia by the same retinal physician (RGP) between December 2012 and July 2015. The anatomic classification of the neovascular lesions was recorded, as well as the number of intravitreal treatments administered and the change in visual acuity (VA) obtained throughout the follow-up. RESULTS: A total number of 174 eyes of 156 patients (mean age: 79.9 years) with a minimum follow-up of 4 months were included. The anatomic classification of choroidal neovascularisation (CNV) showed the presence of type 1 lesions in 40,8%, type 2 lesions in 12%, type 3 lesions in 31%, and mixed lesions in 14.4%, with 1.7% showing polypoidal choroidal vasculopathy features. Overall, the mean baseline VA was 0,32, improving to 0,38 at 24 months, after having received a mean of 9.3 injections. Type 2, 3, and mixed forms showed a visual result significantly lower than type1, but there was no significant difference in the polypoidal vasculopathy. CONCLUSIONS: Type 1 CNV was the most common finding, and was associated with a better visual prognosis, compared to the other neovascular lesions

Atrofia geográfica: etiopatogenia y terapias actuales / Geographic atrophy: Etiopathogenesis and current therapies

La atrofia geográfica se caracteriza por un déficit visual severo cuya etiología y fisiopatología aún están por dilucidar. Como hipótesis de trabajo, el daño oxidativo desencadenaría una inflamación crónica en el complejo membrana de Bruch-EPR-coriocapilar, cobrando protagonismo la activación del complemento. Algunos sujetos con mutaciones en el sistema del complemento y otros factores tienen menor capacidad en la modulación de la respuesta inflamatoria, lo que se traduce en daño celular y acumulación de desechos. Esta acumulación de desechos intracelulares y extracelulares se manifiesta como drusas y alteraciones pigmentarias que preceden a la atrofia de fotorreceptores, EPR y coriocapilar, existiendo un proceso isquémico de base con disminución del flujo coroideo. Todos estos procesos se objetivan como hallazgos tomográficos y signos de la autofluorescencia que son útiles en la evaluación de los pacientes con DMAE atrófica, pudiendo establecer un pronóstico individualizado. Terapias antiinflamatorias, antioxidantes y reductora de la acumulación de toxinas para la preservación de células del EPR y fotorreceptores están siendo investigadas para disminuir el avance de esta enfermedad

Geographic atrophy is characterized by severe visual deficit whose etiology and pathophysiology are yet to be elucidated. As a working hypothesis, oxidative damage could trigger a chronic inflammation in Bruch's membrane-RPE-choriocapillaris complex, mostly due to complement pathway overactivation. Some individuals with mutations in the complement system and other factors have diminished capacity in the modulation of the inflammatory response, which results in cell damage and waste accumulation. This accumulation of intracellular and extracellular waste products manifests as drusen and pigmentary changes that precede the atrophy of photoreceptors, RPE, choriocapillaris with an ischemic process with decreased choroid flow. All these processes can be detected as tomographic findings and autofluorescence signals that are useful in the evaluation of patients with atrophic AMD, which helps to establish an individualized prognosis. Anti-inflammatory, antioxidant and therapies that decrease the accumulation of toxins for the preservation of the RPE cells and photoreceptors are being investigated in order to slow down the progression of this disease

Afectación cardiovascular en pacientes con edema macular diabético tratados con ranibizumab intravítreo en la práctica clínica habitual / Cardiovascular involvement in patients with diabetic macular oedema treated with intravitreal ranibizumab in routine clinical practice

Objetivo: Analizar la afectación cardiovascular a corto plazo de los pacientes naïve con edema macular diabético, tratados con ranibizumab intravítreo, tanto pre- como postratamiento. Material y métodos: Estudio retrospectivo y descriptivo de pacientes con edema macular diabético con afectación central, que hubieran iniciado tratamiento con ranibizumab intravítreo en 2014 en el Hospital Universitario Nuestra Señora de Candelaria y el Hospital Universitario y Politécnico La Fe. Se siguieron hasta agosto de 2015, estudiando, entre otras variables, la prevalencia e incidencia de accidente cerebrovascular y de infarto agudo de miocardio. Resultados: De las 1.324 inyecciones de ranibizumab intravítreo que se administraron en 2014, solo 159 fueron como inicio de tratamiento, repartidas entre un total de 99 pacientes, ya que más de la mitad de ellos precisó tratamiento de ambos ojos (58,6%). El 58,4% de los pacientes fueron hombres, en la sexta década de la vida (X¯=65,93 años ± 11,24) y, en su mayoría, no fumadores (86,7%), diabéticos tipo 2 (91,9%), hipertensos (70,7%) y dislipidémicos (65,7%). Se encontraron 6 pacientes (6,1%) con infarto agudo de miocardio y 8 (8,1%) con accidentes cerebrovasculares (ACV) previos al inicio del tratamiento, y solo uno (1%) con accidente cerebrovascular posterior (p = 0,039). Conclusión: En nuestra experiencia el ranibizumab intravítreo en pacientes con edema macular diabético, con antecedentes de accidente cerebrovascular e infarto agudo de miocardio podría ser una alternativa segura (AU

Objective: To determine the cardiovascular events in naïve patients with diabetic macular oedema, before and after being treated with intravitreal ranibizumab. Material and methods: A retrospective and descriptive study was conducted on patients with diabetic macular oedema and foveal involvement, who started treatment with intravitreal ranibizumab in 2014 in the Hospital Universitario Nuestra Señora de Candelaria and the Hospital Universitario y Politécnico La Fe. During the follow-up until August 2015, a record was made of parameters, including the prevalence and incidence of stroke and myocardial infarction. Results: Among the 1,324 intravitreal ranibizumab injections administered in 2014, only 159 of them corresponded to treatment initiation in 99 patients, with more than half requiring treatment of both eyes. The study patients included 58.4% males, in the 6th decade of life (Mean = 65.93 ± 11.24 years), non-smokers (86.7%), type 2 diabetes (91.9%), hypertension (70.7%), and with dyslipidaemia (65.7%). Prior to treatment initiation, it was found that 6 patients (6.1%) suffered from an acute myocardial infarction, and 8 (8.1%) from stroke, and only one (1%) with post-stroke (P = .039). Conclusion: In our experience it seems that the intravitreal ranibizumab in diabetic macular oedema could be a safe alternative in patients with a history of stroke and myocardial infarction (AU)

Terapias intravítreas en degeneración macular asociada a la edad no neovascular con fluido intrarretiniano o subretiniano / Intravitreal therapies for non-neovascular age-related macular degeneration with intraretinal or subretinal fluid

OBJETIVO: Evaluar la eficacia de las terapias intravítreas en casos de degeneración macular asociada a la edad (DMAE) atrófica con fluido intra- o subretiniano. MÉTODOS: Revisamos, de forma retrospectiva, las características de pacientes diagnosticados de DMAE atrófica con fluido intra- o subretiniano. Examinamos las retinografías y las imágenes de tomografía de coherencia óptica de dominio espectral analizando en ellas la presencia de fluido y su densidad. Descartamos la existencia de neovascularización coroidea mediante angiografía con fluoresceína o con verde de indocianina. RESULTADOS: Se incluyeron 14 ojos de 13 pacientes con una edad media de 72,64 años y un seguimiento medio de 80,5 semanas. Se observó fluido intrarretiniano en 6 ojos (42,9%) y fluido subretiniano en 8 ojos (57,1%). Este fluido era de alta densidad en 4 de ellos (28,5%) y de baja densidad en los otros 4 ojos (28,5%). La mejor agudeza visual corregida evaluada mediante la escala de Snellen mejoró de 0,37 inicialmente a 0,56 en la visita final (p = 0,002). El grosor macular central (en micras) disminuyó de forma significativa de 291,0 μm al inicio a 228,9μm en la visita final (p≤0,001). Del total, 8 ojos recibieron ranibizumab, 5 ojos recibieron bevacizumab y un ojo recibió triamcinolona intravítrea. CONCLUSIONES: La DMAE atrófica puede presentarse con fluido intra- o subretiniano en ausencia de neovascularización coroidea. Son necesarios estudios adicionales para analizar el valor de estos hallazgos como factor de riesgo en el desarrollo de formas avanzadas de DMAE, así como la eficacia de las terapias intravítreas

OBJECTIVE: To evaluate the efficacy of intravitreal therapies in cases of atrophic age-related macular degeneration (AMD) with subretinal or intraretinal fluid. METHODS: A retrospective review was made of the clinical charts of patients diagnosed with atrophic AMD with subretinal or intraretinal fluid. Fundus photographs and spectral-domain optical coherence tomography images were examined, and an analysis was made on the presence of fluid and its density. Neovascularisation was ruled out by fluorescein and/or indocyanine green angiography. RESULTS: The study included 14 eyes from 13 patients with a mean age of 72.64 years and a mean follow-up of 80.5 weeks. Intraretinal fluid was observed in 6 eyes (42.9%), while subretinal fluid was shown in 8 eyes (57.1%), with high density in 4 eyes (28.5%), and low density in 4 eyes (28.5%). Snellen best-corrected visual acuity improved from 0.37 at baseline to 0.56 at the final visit (P=.002). Central subfield thickness (microns) significantly decreased (P<.001) from 291.0 at baseline to 228.9 at the final visit. Eight eyes received ranibizumab, 5 eyes received bevacizumab, and one case received triamcinolone. CONCLUSIONS: Cases of atrophic AMD may present with subretinal or intraretinal fluid in the absence Neovascularisation. Further studies are required to analyse the value of this finding as a risk factor of developing advanced forms of AMD, as well as the efficacy of intravitreal therapies

Impacto funcional del tratamiento con ranibizumab bajo una estrategia reactiva en pacientes con degeneración macular asociada a la edad exudativa neovascular / Functional impact of treatment with ranibizumab under a reactive strategy in patients with neovascular age-related macular degeneration

OBJETIVO: Conocer el porcentaje de recuperación funcional, según estrategia pro re nata (PRN) con inyecciones intravítreas con ranibizumab en pacientes con degeneración macular asociada a la edad (DMAE). MATERIAL Y MÉTODOS: Estudio observacional, retrospectivo, unicéntrico. Se incluyó a pacientes con DMAE tratados con ranibizumab según estrategia PRN y seguimiento mínimo de 18 meses. Se recogieron variables sociodemográficas y clínicas de la historia clínica. El porcentaje de recuperación de agudeza visual (AV) después de perder 5 o más letras fue calculado considerando la AV del mes anterior, así como la mejor AV previa al retratamiento. RESULTADOS: Se analizó a 128 pacientes. La media (DE) de seguimiento fue de 18,9 (2,3) meses; la media (DE) entre los primeros síntomas y el diagnóstico y entre la prescripción e inicio de tratamiento fue de 50,2 (57,4) y 10,9 (16,0) días, respectivamente. Ranibizumab solo fue prescrito en 108 pacientes tras una pérdida de 5 o más letras de AV. La media (DE) de recuperación de AV al considerar la AV de la última visita fue 70,3% (114,4). La media (DE) de recuperación de AV considerando la mejor AV antes del retratamiento fue de 43,5 (112,9), con un 59,4% de retratamientos que presentaron una recuperación de AV inferior al 75%, mientras que el 11,7% no presentaron recuperación de la AV. CONCLUSIONES: Una estrategia PRN con inyecciones intravítreas de ranibizumab podría no ser lo suficientemente efectiva en términos de mantenimiento o recuperación de AV en los casos de DMAE a largo plazo, debido a la pérdida irreversible de AV

OBJECTIVE: To analyse the functional recovery using a pro re nata (PRN) dosing strategy with intravitreal injections of ranibizumab for patients with neovascular age-related macular degeneration (AMD). MATERIAL AND METHODS: An observational, retrospective, single-centre study, was conducted on patients with neovascular AMD managed with a PRN strategy with ranibizumab, and were followed-up for a minimum of 18 months. Sociodemographic and clinical data were collected from medical records. The percentage of visual acuity (VA) recovered after losing 5 or more letters was calculated taking into account the previous visit, as well as considering the best VA recorded prior to the retreament. RESULTS: The analysis included 128 patients. The mean (SD) follow-up period was 18.9 (2.3) months. The mean (SD) elapsed days between onset of symptoms and diagnosis, and between prescription and administration of treatment was 50.2 (57.4) and 10.9 (16.0), respectively. Only 108 patients were prescribed ranibizumab after losing 5 or more letters of VA. The mean (SD) VA recovery compared to the previous VA was 70.3% (114.4). On the other hand, the mean (SD) VA recovery when considering the best VA registered before the retreatment was 43.5% (112.9), with 59.4% of re-treatments having a VA recovery below 75%, and with 11.7% not presenting any VA recovery. CONCLUSIONS: A PRN dosing strategy with intravitreal ranibizumab for neovascular AMD may not be efficient in preserving and/or recovering VA in the long-term, due to a cumulative irreversible VA loss

Implicaciones de la clasificación anatómica de la forma neovascular de la degeneración macular asociada a la edad / Implications of the anatomical classification of the neovascular form of age-related macular degeneration

OBJETIVOS: Presentar la relevancia clínica de la clasificación anatómica de la forma neovascular de degeneración macular asociada a la edad (DMAE). MÉTODOS: Análisis crítico de la situación actual de la gestión de pacientes con DMAE neovascular revisando la evidencia científica disponible respecto a la clasificación de los tipos de lesión neovascular por angiografía y por tomografía de coherencia óptica (OCT). RESULTADOS: La clasificación del tipo de lesión neovascular secundaria a DMAE mediante OCT en lesiones de tipo 1 (por debajo del epitelio pigmentario), de tipo 2 (subretinianas) y de tipo 3 (proliferación angiomatosa retiniana), aporta un valor añadido permitiendo establecer un pronóstico visual a largo plazo, una estimación del número de tratamientos que un caso pueda requerir y una estratificación del riesgo de atrofia geográfica secundaria. CONCLUSIONES: Incorporar la OCT en el análisis cualitativo inicial de los casos de DMAE neovascular ofrece un valor añadido superior al de la angiografía con implicaciones prácticas relevantes

OBJECTIVE: To present the clinical relevance of the anatomical classification of the neovascular form of Age-Related Macular Degeneration (AMD). METHODS: Critical analysis of the current situation in the management of patients with neovascular AMD, by reviewing the available scientific evidence with regards to the classification of the types of neovascular lesion by angiography and optical coherence tomography (OCT). RESULTS: The classification of the neovascular lesion type secondary to AMD by OCT in type 1 lesions (under the pigment epithelium), type 2 (subretinal), and type 3 (retinal angiomatous proliferation), provides an added value in allowing to establish a long-term visual prognosis, an estimate of the number of treatments that a certain case may require, and a stratification of the risk for secondary geographic atrophy. CONCLUSIONS: Incorporating OCT to the initial qualitative analysis of cases with neovascular AMD offers an added value superior to that provided by the angiography, with the relevant clinical implications
