Acute retinal necrosis syndrome complicating chickenpox.

Chickenpox may be complicated by ocular involvement. In these patents, acute retinal necrosis usually forms a relatively mild course. Systemic antiviral treatment during the acute phase of the disease is recommended. Rarely, retinal detachment may develop, resulting in blindness. It is strongly recommended that patients with chickenpox who develop visual symptoms should be referred for an ophthalmological opinion early.
