Healing patterns of choroidal tubercles after antitubercular therapy : A photographic and OCT study

A 28-year-old female patient with disseminated tuberculosis and choroidal tubercles on a regimen of systemic antitubercular therapy underwent fundus photography and optical coherence tomography (OCT). This was carried out monthly until complete healing of the tubercle was seen. The tubercle consisted of a central white-yellow core, consistent with choroiditis, with a faint hyperpigmentation surrounding it. There was a surrounding diffuse rim of inflammation. By the second month, the hyperpigmented rim was more prominent as were the outer edges of both the central core and the outer rim. Over time, the outer rim had largely faded with concurrent scar formation in the core. The initial OCT analysis revealed a raised RPE-choriocapillaris complex. With healing, there was a marked reduction in the choroidal lesional height suggesting resolution.
