Abstract
Episcleritis is rarely reported to be associated with tuberculosis (TB). In this review, we highlight this underreported entity and elaborate on the natural history of the reported cases in the literature. Eighteen articles were found to describe numerous cases throughout the past century. Forty patients diagnosed with tuberculous episcleritis were found in the literature. The majority of the patients presented with a latent form of TB and fewer cases were linked with active/pulmonary disease. The natural history of episcleritis was found to have chronic and recurrent attacks refractory to traditional treatment, and the most commonly reported type was the nodular form. The described cases were eventually treated by quadruple antituberculous therapy, and fortunately, recurrence after treatment completion was not documented. It is imperative to highlight such entities that may be underreported in endemic countries, as successful therapy would decrease ocular morbidity and prevent potential unforeseen tuberculous complications.
