Diffuse anterior scleritis following micropulse transscleral laser

We report a case of scleritis following micropulse transscleral laser therapy (TLT) in an elderly female with medically uncontrolled primary open-angle glaucoma. She had completed antitubercular treatment (ATT) for pulmonary tuberculosis 20 years ago. Along with scleritis, there were vitritis and macular edema post laser. Systemic blood investigations for connective tissue disorders were negative. She had latent tuberculous infection with positive Mantoux test and quantiferon TB gold. She responded favorably to topical steroids with no vision loss. Though TLT, with its pulsed laser delivery, is considered safe, caution must be exercised in patients susceptible to inflammation.
