Acute retinal necrosis is a viral syndrome characterized by a panuveitis with necrotizing retinitis that may be complicated by retinal detachment, vaso-occlusion, optic neuropathy, and other causes of decreased visual acuity. Polymerase chain reaction testing provides a rapid and sensitive method of identifying the viral etiology of acute retinal necrosis, which is most commonly caused by herpes simplex virus type 1, herpes simplex virus type 2, and varicella zoster virus. Prompt diagnosis and treatment is paramount to prevent further vision loss. We review the management of acute retinal necrosis including systemic, local intravitreal, and combination antiviral medications. We also discuss the appropriate and inappropriate use of corticosteroids, laser retinopexy, surgical therapy, and other adjunctive measures.
