We report the results in two patients received prophylactic surgery to prevent retinal detachment in the severe acute retinal necrosis.

Two patients in whom the presumptive diagnosis of the severe acute retinal necrosis were concomitantly treated with antiviral agents, systemic steroids and anti platelet therapy. We performed vitrectomy and silicone oil tamponade as the prophylactic surgical procedure for retinal detachments. The retinas remained attached in all patients over a follow up periods.

Retinal detachment secondary to acute retinal necrosis has a complex nature and usually results in severe visual loss. A combination of vitrectomy and silicone oil tamponade may be effective prophylaxes against retinal detachment in acute retinal necrosis.
