Ocular manifestations of systemic tuberculosis: Report of 3 cases

Tuberculosis is a chronic infectious disease caused by mycobacteria species, which can affect any organ of the body including the eye. Primary ocular tuberculosis is very rare condition and likely to be caused by introduction of bacilli through epithelial injury. Post primary infections (or secondary infection) due to direct hematogenous spread or contiguous spread from an adjacent structure are more common presentations of ocular tuberculosis. The authors experienced 3 cases of ocular tuberculosis associated with systemic infection. One case was a scleral involvement of miliary tuberculosis and the others were choroidal tuberculoma from systemic tuberculosis.
