Retinal Vascular Parameters Changes (by Optical Coherence Tomography Angiography) in Early Rheumatoid Arthritis: A Hospital-Based Study

OCTA can detect early retinal microcirculation affection in RA patients in the form of a reduction in the vascular density in most of the subfields of the peripapillary area as well as the fovea, perifoveal, and parafoveal areas. The results of the current study can provide new insight into the applications of OCTA as a diagnostic tool in RA patients' assessment and follow-up.
