Clinical Features of Acute Retinal Necrosis with Optic Neuropathy and Central Retinal Artery Occlusion as Initial Manifestations

Abstract

Acute retinal necrosis normally occurs at the periphery retina and gradually merges and progresses to the posterior pole. Optic neuropathy and central retinal artery occlusion as initial manifestation is very rare. We report the case of a patient with optic neuropathy and central retinal vessels as the first manifestations of acute retinal necrosis. Antiviral drugs, corticosteroids, and drugs that improve blood circulation were given. The necrotic retina and swollen optic disc disappeared gradually. However, the final vision of this eye declined to no light perception. From the first case report in 2001 to now, a total of 8 sporadic cases have been reported. The average onset age is 60.85±14.05 years. Most of them had no history of virus infection. Cardiovascular disease history maybe a risk factor. Acute retinal necrosis should be considered in patients with retinal vascular occlusion accompanied by granulomatous anterior uveitis. Further research is needed to determine whether treatments in addition to antiviral and corticosteroid therapy are needed.
