OCTA artifacts from cystoid macular edema. OCTA decorrelation artifacts can be generated by the walls around cystoid spaces. (A) OCTA artifact in an eye with diabetic cystoid macular edema (arrow). There are no blood vessels in the wall of the cystoid space. (B) The false color flow density map shows a low level of flow in the corresponding area (arrow) although no flow is present. These structures exhibit small displacements between repeated B-scans, generating false OCTA signals.
