«Optical Coherence Tomography» en desgarro del epitelio pigmentario retiniano

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.
