9.2.3.5 Optical Coherence Tomography Angiography

Newer imaging modalities such as optical coherence tomography angiography (OCTA) are being increasingly used in the evaluation of posterior uveitides such as TB-related choroiditis. Using OCTA, choriocapillaris hypoperfusion in association with TB SLC is seen as flow void areas on en face OCTA. These correlate well with findings on ICGA. Thus, noninvasive tools such as OCTA may enable detailed evaluation of the retinochoroidal vasculature among patients with intraocular TB [30]. In a recent report, choroidal neovascularization was detected using OCTA in a patient with tubercular choroiditis [31]. Thus, further advances in imaging may enhance our knowledge of pathogenesis of intraocular TB.
