Cytopathology and Polymerase Chain Reaction of Vitreous Fluid in Tubercular Intermediate Uveitis.

Purpose: Cytopathology of vitreous is most commonly done to diagnose vitreoretinal lymphoma in eyes with nonspecific inflammation. Vitreous cytopathology features of tuberculous intermediate uveitis have not been described in literature.Case report: We report a case of a healthy 35-year-old female who showed granulomatous inflammatory changes on vitreous cytopathology with polymerase chain reaction confirming a diagnosis of intraocular tuberculosis.Conclusion: This case highlights the role of cytopathology in determining the etiology and pathogenesis behind the elusive diagnosis of intermediate uveitis. Polymerase chain reaction can further help in confirming the diagnosis and allowing commencement of appropriate therapy.
