A case of subretinal tubercular abscess presenting as disc edema.

We report a case of ocular tuberculosis (TB) which initially presented with disc edema and was mistaken for optic neuritis. With no definite pathology being identified, the patient was treated on the lines of optic neuritis with intravenous (IV) steroid with beneficial effect. Ocular TB was suspected when he presented later with a subretinal abscess. Based on positive Mantoux, QuantiFERON TB gold results and radiographic findings, a diagnosis of subretinal abscess of presumed tubercular etiology was made. The patient was successfully treated with anti-tubercular therapy. To the best of our knowledge, this is the first case report of ocular TB presenting as disc edema followed by subretinal abscess.
