La retinitis necrotizante aguda, es una necrosis retinal de todas las capas de la retina. Se caracteriza por necrosis fibrinoides de la pared de los vasos y oclusión vascular. Se presentó un caso de una paciente de 42 años de edad, con pérdida brusca de la visión del ojo derecho, con una semana de evolución. Al examen oftalmológico se observó haze vítreo 2+, edema sucio del disco óptico, con borramiento de todos sus bordes. Presencia de exudación blanca-amarillenta retiniana extensa, en toda la periferia y área ecuatorial asociada a hemorragias intraretinianas. Se realizó además del examen fundoscòpico toma de muestra de humor acuoso para reacción en cadena de la polimerasa y angiografía fluoresceínica. Los signos fundoscópicos de la paciente, así como las anomalías detectadas en la angiografía fluoresceínica sugirieron el diagnóstico clínico de síndrome de necrosis retinal aguda. Se confirmó el diagnóstico etiológico viral, semanas después por el resultado de polimerasa. Se practicó la terapéutica médica y fotocoagulación laser focal retiniano correspondiente, asociado a cirugía del desprendimiento de retina mixto mediante vitrectomía pars plana y se logró la re aplicación de la retina.

The acute necrotizing retinitis is a retinal necrosis of all the retinal layers. It is characterized by fibrinoid necrosis of the vases’ wall and vascular occlusion. The case presented is the case of a female patient aged 42 years, who suffers sudden loss of the left eye vision, with a week of evolution. At the ophthalmologic examination it was observed a 2+ vitreous haze, dirty edema of the optic disk, with effacement of all of its margins. There it was an extended white-yellowish retinal exudation in the entire periphery and the equatorial area, associated to intra-retinal hemorrhages. Besides the funduscopic examination, it was taken a sample of the aqueous humor for a polymerase chain reaction (PCR) and fluorescein angiography. The patient’s funduscopic signs, and also the anomalies detected in the fluorescein angiography suggested the clinical diagnosis of acute retinal necrosis syndrome. After several weeks, the viral etiologic diagnosis was confirmed by polymerase chain reaction. It was practiced the correspondent medical therapeutics and focal retinal laser coagulation associated to mixt retinal detachment through pars plana vitrectomy; the retina reapplication was achieved.
