Unilateral snow banking in tuberculosis-related intermediate uveitis

Abstract

Snow banking is usually a term coined to describe the accumulation of vitreous exudates over the pars plana and the peripheral retina in pars planitis. Snow banking is very rare in tubercular intermediate uveitis. A 32-year-old male was diagnosed to have intermediate uveitis due to tubercular etiology in the right eye. Laboratory investigations include an increased erythrocyte sedimentation rate, positive Mantoux test, and computed tomography thorax showing mediastinal lymphadenopathy. Transbronchial needle aspiration of the lymph nodes showed chronic granulomatous inflammation with caseation. There were no recurrences following antitubercular therapy (ATT). This case report highlights the unique finding of snow banking in tubercular uveitis and course following treatment with ATT.
