Purpose: To report a case of ocular co-infection with Mycobacterium tuberculosis and Toxoplasma gondii in an immunocompetent woman. Method: Retrospective observational case report. Result: A 61-year-old woman presented with decreased vision and floaters in the right eye of 1-month duration. Ocular examination revealed panuveitis with a large yellowish-white retinochoroiditis lesion adjacent to a chorioretinal scar. Investigations showed positive Mantoux test, QuantiFERON TB test, and HRCT chest suggestive of active pulmonary tuberculosis. Serology revealed raised IgG anti T. gondii antibody. Vitreous aspirate was positive for M. tuberculosis and T. gondii genome by polymerase chain reaction and showed high IgG and IgM T. gondii antibodies. She was treated with anti toxoplasmic and antitubercular therapy along with oral corticosteroid and therapeutic vitrectomy. Conclusion: Ocular tuberculosis and toxoplasmosis can not only mimic each other but also present as co-infection in rare cases.
