Abstract: The aim of this study was to report a case of acute retinal necrosis (ARN) after intraocular foreign body removal. A 32-year-old male presented with visual loss in the left eye. He was hit by an iron fragment while he was hammering. An intraocular foreign body was found with corneal laceration and traumatic cataract. On the day he was injured, primary closure of the laceration, lensectomy, and vitrectomy were performed, and the foreign body was removed. The day after the operation, there was no sign of retinal detachment or retinitis. Two days after the operation, retinal necrosis and accompanying vitreous inflammation were noted in the far periphery. On day 3, the necrosis spread circumferentially and inflammation became more distinct. ARN was presumed and intravenous acyclovir was administered. The necrotic areas were reduced 2 days later, and were resolved in 1 month. The final visual acuity in his left eye was 20/20 after implantation of an intraocular lens. This case is the first report of ARN after penetrating injury and an intraocular foreign body. ARN may develop after open-globe injury.
