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)

Incidencia y resultados clínicos de las distintas formas neovasculares de degeneración macular asociada a la edad en Valencia (España) / Incidence and clinical outcomes of the different neovascular forms of age-related macular degeneration in Valencia (Spain)

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

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

Coriorretinitis placoide sifilítica. Caso clínico / Syphilitic placoid chorioretinitis. A case-report

CASO CLÍNICO: Presentamos el caso de una mujer de 45 años sin antecedentes de interés y con una pérdida súbita de visión en su ojo izquierdo secundaria a una uveítis posterior bilateral. Tras despistaje, se diagnosticó de coriorretinitis placoide posterior aguda sifilítica, y recibió tratamiento con penicilina intravenosa. Discusión: Existen múltiples manifestaciones oculares de la sífilis que pueden simular cuadros y etiologías muy diversas. El tratamiento anti-treponémico normalmente produce una rápida y positiva respuesta en pacientes afectos. El diagnóstico precoz y certero de estos pacientes es por tanto crucial aunque, en ocasiones, los daños anatómicos y funcionales son irreversibles

CLINICAL CASE: We report the case of a 45-year-old woman, with unremarkable past medical history, who presented with acute visual loss in her left eye due to bilateral posterior uveitis. After the screening, she was diagnosed with acute syphilitic placoid chorioretinitis and was treated with intravenous penicillin. DISCUSSION: Clinical manifestations of ocular syphilis are extremely heterogeneous and may mimic several aetiologies. Anti-treponema treatment usually induces a quick and positive response in affected patients. Prompt and proper diagnosis of these patients is crucial, although anatomical and functional damage may persist
