Swept-source Optical Coherence Tomography Angiography Findings in Uveitic Cystoid Macular Edema.

: To describe swept-source optical coherence tomography angiography (OCTA) findings in uveitic cystoid macular edema (CME).: Prospective study of 36 eyes.: Cystoid black spaces were shown in the deep capillary plexus (DCP) in 36 eyes (100%) and in the superficial capillary plexus (SCP) in 6 eyes (16.7%). Grayish areas of capillary non perfusion/hypoperfusion were seen in 69.4% of eyes in the DCP (vs 25% in the SCP, < .001). The foveal avascular zone was larger than in the control healthy eyes in the DCP ( < .001). Capillary density was lower than in the control group in the SCP ( = .001) and the DCP ( < .001). Of 11 eyes with resolved CME on OCT, 4 eyes showed complete recovery of both plexuses on OCTA. There was a persistence of areas of capillary rarefaction in 4 eyes, and of hypoperfusion/nonperfusion in 3 eyes.: OCTA visualizes perifoveal microvascular changes in uveitic CME.
