Macular Optical Coherence Tomography Angiography Parameters in Central Retinal Vein Occlusion and Differentiation of Ischemic and Non-Ischemic Types
Aim:To evaluate the macular microvascular parameters in central retinal vein occlusion (CRVO) and to differentiate its ischemic and non-ischemic types.Methods:This study included 32 affected and 32 unaffected eyes of patients with unilateral CRVO and 32 age and sex-matched healthy control eyes.
