    Evaluation of the retinal and choroidal microvasculature changes in cases of sarcoid and tuberculosis-associated posterior uveitis using OCT angiography

    Purpose: Using optical coherence tomography angiography (OCTA) to evaluate retinal microvascular changes in sarcoid and tuberculous (TB) posterior uveitis. Methods: Cross-sectional observational study includes 30 eyes. FFA and OCTA images were acquired. OCTA images were analyzed for areas of capillary hypo-perfusion, disorganization of the superficial and deep capillary plexuses (SCP and DCP) and intraretinal cystoid spaces and for measuring the size of the foveal avascular zone and vessel density (VD) in the SCP and DCP. Results: A total of 11 eyes were associated with TB and 19 with sarcoidosis. By OCTA, 100% had areas of capillary non-perfusion, 36.7% choroidal ...
