BACKGROUND: ARN syndrome follows severeintraocular @entity281 by herpes viruses and primarily affects the peripheral retina. Following scar formation, despite antiviral treatment, @entity1713 occurs very often. Prophylactic argon laser photocoagulation has therefore been proposed. We report our experience. @entity1 : We treated five @entity1 presenting clinically with advanced unilateral ARN with @entity1033 . All eyes received a prophylactic confluent double row of @entity3503 laser treatment (500 microns, 0.2 s, gray-white lesions) central to the affected area as soon as was possible, depending on the vitreous clouding. Four @entity1 were treated with Aspirin. RESULTS: One of the five @entity1 had a @entity1713 that was limited by the argon laser row. Another @entity1 had a tractional detachment needing vitreoretinal surgery. Two eyes developed @entity548 of unknown origin. CONCLUSION: A lower rate of rhegmatogenous @entity1713 than expected occurred post-laser treatment. @entity548 was more frequent than previously reported. The @entity548 probably originated from @entity2479 and may have been enhanced by @entity117 treatment. We recommend early prophylactic argon laser photocoagulation in all ARN @entity1 in agreement with the results of previous studies.
