Pulmonary tuberculosis treated 45 years ago and retreated 5 years after the first treatment. His initial visual acuity with correction e was couting fingers at 5 meters for the right eye and for the left eye was 1,0.The fundus examination revelead optical disc blurring, periparillary subretinal hemorrhage and a macular star. Purified protein derivative (PPD) skintesting was not reactant. Laboratory investigation was negative. The chest radiograph did not show significant changes.The diagnosis of ocular TB was presumed. The patient was put on oral steroid & on full antituberculosis treatment(ATT) with Isoniazid 600mg/day, Rifampicin 300mg/day, Pyrazinamid1600mg/Day and Ethambutol1100mg/day.
