ABSTRACT
Purpose: To describe swept-source optical coherence tomography angiography (OCTA) findings in uveitic cystoid macular edema (CME).
Methods: Prospective study of 36 eyes.
Results: 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, p < .001). The foveal avascular zone was larger than in the control healthy eyes in the DCP (p < .001). Capillary density was lower than in the control group in the SCP (p = .001) and the DCP (p < .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.
Conclusion: OCTA visualizes perifoveal microvascular changes in uveitic CME.
