USE OF THE ISCHEMIC INDEX ON WIDEFIELD FLUORESCEIN ANGIOGRAPHY TO CHARACTERIZE A CENTRAL RETINAL VEIN OCCLUSION AS ISCHEMIC OR NONISCHEMIC

Purpose: To understand the relationship between baseline ischemic index (IsI) values on ultra-widefield fluorescein angiography and classification as ischemic central retinal vein occlusion (CRVO). Methods: Single-center retrospective cohort study of CRVO patients imaged using ultra-widefield fluorescein angiography from which IsI values were calculated. An ischemic CRVO was defined as those eyes with an afferent pupillary defect and counting...
