Abstract

Acute retinal necrosis (ARN) is an inflammatory condition characterized by a peripheral retinal necrosis due to an infection with varicella-zoster virus or herpes simplex virus. It is commonly seen in immunocompetent adults and is known for its rapid evolution and poor prognosis. Our case study illustrates the gravity of this condition with an extremely rapid ARN that was hard to diagnose.

Highlights

  • Acute Retinal Necrosis syndrome (ARN) is a rare viral disease with a fast evolution.Acute retinal necrosis (ARN) was first described by Uryama in 1971 [1]

  • In 1994 this clinical entity was defined as the association of retinal necrosis extending from the periphery to the center of retina, occlusive arterial vascularitis and an anterior segment acute inflammation [2]

Summary

INTRODUCTION

Acute Retinal Necrosis syndrome (ARN) is a rare viral disease with a fast evolution. ARN was first described by Uryama in 1971 [1]. It was associated- few years later- with the Herpes Virus subfamily infection. In 1994 this clinical entity was defined as the association of retinal necrosis extending from the periphery to the center of retina, occlusive arterial vascularitis and an anterior segment acute inflammation [2]. The poor prognosis of the ARN as well as its fast evolution makes on the top of the ocular emergencies. We report a case of a unilateral ARN with an extremely rapid progression, posing as a challenge like no other for our ophthalmological emergency department
