Surgically Induced Necrotizing Scleritis Following Strabismus Surgery Treated Successfully with Topical N-acetylcysteine in a Child with Congenital Fibrosis of Extraocular Muscles and Varadi Papp Syndrome

Abstract

Surgically induced necrotizing scleritis (SINS) is a rare but serious disorder that can develop many years after strabismus surgery. It is generally treated with high-dose steroids or immunosuppression. We describe a patient with Varadi Papp syndrome and congenital fibrosis of the extraocular muscles, who developed surgically induced necrotizing scleritis a month after strabismus surgery and was successfully managed by oral vitamin C and topical N-acetylcysteine 10%. While SINS is conventionally treated with steroids/immunosuppression, a conservative approach may be tried in milder cases. The role of topical N-acetylcysteine in managing this complication needs to be explored.
