espanolCaso clinico: Varon de 55 anos, sin drusas ni alteraciones del epitelio pigmentario sugestivas de degeneracion macular asociada a la edad (DMAE), que presento maculopatia exudativo-hemorragica. La angiografia con fluoresceina e indocianina verde mostraron la proliferacion angiomatosa retiniana (PAR), la arteriola aferente y venula retinianas de drenaje. La respuesta fue optima a un unico tratamiento con terapia fotodinamica. Discusion: La PAR es una lesion descrita en los ultimos anos en el contexto de la DMAE, cuya principal caracteristica es la lesion neovascular formada a partir de capilares retinianos y su extension posterior al espacio subretiniano. Nuestro paciente presentaba los hallazgos tipicos de PAR sin DMAE. EnglishCase: A 55-year-old male was diagnosed with exudative-hemorrhagic maculopathy, with no signs observed of drusen or pigmentary epithelium defects suggestive of age-related macular degeneration (ARMD). Fluorescein angiography (FA) and indocyanine green choroidal angiography (ICGA) showed retinal angiomatous proliferation (RAP). Afferent arteriole and retinal drainage venule connection was also observed. Treatment with a single Photodynamic Therapy provided an optimal outcome. Discussion: RAP is a form of neovascular ARMD described in recent years; it consists of an angiomatous proliferation that originates from the retinal capillary system and extends posteriorly into the subretinal space. Our patient showed typical RAP findings without any sign of ARMD.

espanolCasos clinicos: Se presentan 3 pacientes con desgarro de epitelio pigmentario retiniano (EPR). En dos de ellos, este se produjo de manera espontanea, estando el tercero en relacion con la fotocoagulacion de una neovascularizacion extrafoveal. Se realizaron angiografias (AGF) y estudio con tomografia optica de coherencia (OCT) que confirmaron el diagnostico. Discusion: Existen pocos estudios sobre OCT en desgarro del EPR. Las principales caracteristicas son: interrupcion de la linea hiperreflectante del EPR, hiperreflectividad de la coroides en la zona de ausencia de EPR y doble capa de EPR donde este esta replegado. Es frecuente el desprendimiento de EPR y neurosensorial asociado. EnglishCase reports: Three cases of pigmentary epithelial tears are described in this study. One of them was related to previous extrafoveal photocoagulation, whereas the other two were idiopathic. Fluorescein angiography (FA) and optical coherence tomography (OCT) were performed to confirm the clinical diagnosis. Discussion: Few studies using OCT to assess pigmentary retinal epithelial (RPE) tears have been published in the world literature. The main findings of our study included hyper-reflectant line breaks, choroidal hyper-reflectance due to the lack of RPE and RPE double layering where it was folded. Images were frequently associated with RPE tears and neurosensorial retinal detachment.

espanolObjetivo: Detectar la incidencia de edema macular quistico (EMQ) tras cirugia de catarata tanto clinico como subclinico, mediante «ocular coherence tomography» (OCT) y comparar dicha incidencia entre un grupo de pacientes diabeticos y otro de no diabeticos. Material y metodos: Estudio prospectivo de 260 ojos intervenidos de forma consecutiva de catarata mediante facoemulsificacion con implante de lente intraocular acrilica, desde septiembre de 2004 a marzo de 2005. Grupo A: 208 ojos de pacientes no diabeticos, grupo B: 42 ojos de pacientes diabeticos, grupo C: 10 ojos de pacientes diabeticos con edema macular y que recibieron triamcinolona intravitrea (TAIV) al finalizar la cirugia. En cada revision efectuada a los 6 dias (basal), 5 semanas y 12 semanas se realizo biomicroscopia de polo posterior y OCT. Resultados: El espesor macular en la OCT, fue significativamente superior en el grupo B que en el grupo A (241,6 versus 204,6 µm p- 43,74 µm (2 DE del valor basal del grupo A). En el grupo B, seis ojos presentaron EMQ clinicamente significativo, con disminucion de agudeza visual (14,2%), en 12 ojos detectamos aumento del espesor macular (28,5%). Las diferencias entre grupos fueron significativas (p EnglishPurpose: To determine the incidence of cystoid macular edema (CME) by means of clinical evaluation and subclinical assessment by means of ocular coherence tomography (OCT), and to compare the incidence between diabetic and non-diabetic groups of patients. Methods: Prospective study of 260 consecutive cataract surgeries operated from September 2004 to March 2005. The procedures were performed by means of phacoemulsification plus intraocular acrylic lens implantation. Group A: 208 eyes of non-diabetic patients; Group B: 42 eyes of patients with diabetes and Group C: 10 eyes of diabetic patients with macular edema that received an intravitreal injection of triamcinolone at the end of surgery. Postoperative follow-up visits were performed 6 days (basal visit), 5 weeks and 12 weeks after surgery. Each visit included posterior pole biomicroscopy and OCT. Results: Central macular thickness measured by OCT was significantly increased in group B compared with group A (241.6 versus 204.6 µm; p
