Objectives:
Ocular tuberculosis is a rare form of extra pulmonary tuberculosis. It represents 1-2% of all clinical forms. The aim of this work was to focus on diagnostic and therapeutic characteristics of ocular tuberculosis.
Methods:
We report a case series of 14 patients with ocular tuberculosis seen in an infectious diseases department between 2006 and 2015. The diagnosis was retained on clinical data and a positive tuberculin skin test or interferon-gamma release assay.
Results:
The patient's mean age was 40.7±9years. The most common clinical presentation was uveitis (11 patients and 16 eyes). An extra ocular involvement was associated in three patients. The mean duration of antitubercular therapy was 10±2.5 months. Corticosteroid therapy was associated in 11 cases. The outcome was favorable in all cases. Two patients had maintained visual sequelae.
Conclusion:
Ocular tuberculosis is a rare disease but still remains a diagnostic problem. It should be considered in case of any chronic ocular symptoms, especially in endemic countries. Early management can improve the visual prognosis.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
