Acute necrotizing retinitis. Case report

Abstract

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.
