Swept source OCTA reveals a link between choriocapillaris blood flow and vision loss in a case of tubercular serpiginous-like choroiditis

Optical coherence tomography angiography (OCTA) is a non-invasive technique that is useful in the diagnosis and management of patients with posterior uveitis. Here we report the use of swept source OCTA (SS-OCTA) in a patient with tuberculosis (TB) associated serpiginous like choroiditis (TB-SLC) that made a full visual recovery following treatment with ATT, local and systemic corticosteroids, and systemic immune modulation. By comparing en face images of choriocapillaris (CC) blood flow before and after treatment, we conclude that the patient's visual recovery was associated with resolution of extensive CC flow deficits. This case highlights the utility of SS-OCTA in the multimodal evaluation of patients with choroidal inflammation, and the potential for good visual recovery in patients treated for TB-SLC.
