    Autoimmune retinopathy: findings and limitations from optical coherence tomography angiography

    Background and objective To report novel findings and limitations from optical coherence tomography angiography (OCTA) in the evaluation of autoimmune retinopathy (AIR). Study design We retrospectively reviewed features of five patients diagnosed with AIR and five controls. OCTA scans were obtained and manually segmented to provide accurate measurements of foveal avascular zone (FAZ), vessel density, and retinal thickness at different levels. Results The total retina and superficial vessel density throughout the whole scan were similar between AIR and controls ( p  = 0.14 and p  = 0.11), whereas deep vessel density was decreased in AIR compared controls ( p  = 0.02). Decreased ...
