Surgically induced scleral necrosis associated with concomitant tuberculosis infection: a diagnostic challenge

OBJECTIVE: Surgically induced scleral necrosis (SISN) is a potentially blinding sequela that may occur after any ocular procedure. SISN in the context of active tuberculosis is seldom seen. We report a case of a patient with asymptomatic tuberculosis who developed SISN after pterygium surgery. METHODS: A 76-year-old Mexican-mestizo woman from Veracruz, Mexico, was referred to our clinic because of severe disabling pain and scleral thinning in her right eye. RESULTS: Tubercular-related SISN was finally diagnosed and managed successfully with antitubercular therapy, topical and systemic corticosteroids CONCLUSION: Tuberculosis must be considered as a differential diagnosis of high-risk patients in the context of refractory SISN in endemic countries.
