ABSTRACT
La causa más frecuente de complicaciones visuales enel postoperatorio de cirugía no oftalmológica es la neuropatía óptica isquémica. La incidencia es variabledependiendo de las series publicadas, en la mayoría deellas, la cirugía de raquis realizada en decúbito pronoaparece implicada.Exponemos el caso de una mujer de 47 años que trasuna artrodesis lumbar, con unas pérdidas hemáticas deunos 900 mL, desarrolló una ceguera prácticamentetotal en el ojo izquierdo. En el examen oftalmológicorealizado, fondo de ojo, angiofluoresceingrafía, campimetría y potenciales evocados visuales se diagnosticó una neuropatía óptica retrolaminar, que evolucionó desfavorablemente
Ischemic optic neuropathy is the most common cause ofvisual complications after non-ophthalmic surgery. Theincidence has varied in different case series, but prone-position spine surgery appears to be involved in most of the reports.We present the case of a 47-year-old woman whodeveloped near total blindness in the left eye followinglumbar spine fusion surgery involving the loss of 900 mLof blood. An ophthalmic examination including inspectionof the ocular fundus, fluorescein angiography, and visualevoked potentials returned a diagnosis of retrolaminaroptic neuropathy. Outcome was poor (AU)
