We present the case of a 63-year-old immunocompetent man with unilateral acute retinal necrosis (ARN). He consulted for blurred vision, eye pain, photophobia, and headache. Papillitis and peripheal chorioretinitis associated with vasculitis and peripheral retinal ischemia was confirmed. PCR from aqueous humor sample detected varicella zoster virus. The patient was treated with a combined therapy of oral corticosteroids, oral / intravenous acyclovir along with weekly intravitreous ganciclovir

Follow-up showed improvement in the inflammatory condition and a slight recovery of visual acuity, however, finally he presented a retinal detachment with total loss of one-sided vision. ARN is an uncommon complication caused by some herpesviruses with a poor visual prognosis, an outcome that can be improved with early diagnosis and treatment using appropriate antivirals. Prolonged treatment reduces relapse frequency and fellow eye compromise.
