Recurrent scleral abscess: A unique presentation of latent tuberculosis in the eye

We report a unique case of a 38-year-old woman treated for left eye (LE) diffuse scleritis with topical steroids and anti-inflammatory tablets. Citing no improvement, she consulted our hospital. Mantoux test was positive. A diagnosis of scleral abscess was made. Abscess sample was negative for bacteria, acid fast bacilli (AFB) and fungi. Based on QuantiFERON-TB (QFT), she was tentatively diagnosed with ocular tuberculosis. Pulmonology consult advised antitubercular treatment (ATT). Patient did not start ATT. Five days later, she presented with a new scleral abscess. Tissue biopsy showed necrotizing granulomas. ATT was started followed by systemic steroids, and the patient recovered completely.
