retinal necrosis, acute
A necrotizing retinitis caused by the varicella-zoster virus or herpes simplex virus types 1 and 2, which may infect healthy individuals of any age. The patient usually presents with ocular discomfort, reduced visual acuity and floaters. The signs are those of anterior granulomatous uveitis. There are typically many areas of retinitis, which eventually coalesce ending in full thickness retinal necrosis. Treatment is with antiviral agents, followed by systemic steroids.
