Necrotizing Scleritis Post Cataract Surgery: A Diagnostic Dilemma.

Scleral necrosis following ocular surgery can lead to significant ocular and systemic complications. The two most prevalent procedures associated with surgically-induced scleral necrosis are pterygium excision and cataract surgery. This condition represents a rare delayed hypersensitivity reaction. We present a case of a male patient in his late 60s from India who experienced progressive scleral necrosis in his right eye six months after undergoing small-incision cataract surgery (SICS). The patient exhibited pain and redness without any decline in vision, and all systemic evaluations returned normal results. Ultimately, he was scheduled for a scleral patch graft. This case emphasizes the necessity for rapid diagnosis of surgically-induced necrotizing scleritis (SINS) and timely intervention.
