Evaluation of retinal vascularization by optical coherence tomography angiography (OCTA) in rheumatoid arthritis, and its relationship with disease activity.

Purpose: To measure the retinal capillary density quantitatively with optical coherence tomography angiography (OCTA) in patients with rheumatoid arthritis (RA) and healthy controls (HCs), and to evaluate the relationship between OCTA findings and RA disease activity.

Methods: In this cross-sectional study, 106 eyes of RA patients and 71 eyes of HCs were evaluated. RA patients were divided into inactive (DAS28 < 3.
