Purpose: To report a case of periocular necrotizing fasciitis with toxic shock syndrome. Methods: This is a case report of a previously healthy 69-year-old woman with left preseptal eyelid infection that spread rapidly and deteriorated into necrosis of the eyelid with toxic shock syndrome. She was admitted to intensive care unit for hemodynamic stabilization. Results: Intravenous antibiotic and high-dose immunoglobulin were administered followed by surgical debridement. Rehabilitative eyelid reconstruction was performed after acute episode, resulting in patient satisfaction in relation to periocular function and appearance. Conclusion: We reported a case of periocular necrotizing fasciitis with toxic shock syndrome that necessitated early aggressive medical treatment and adequate surgical intervention to decrease morbidity and mortality. A high level of suspicion of periocular necrotizing fasciitis is necessary to make a prompt diagnosis.
