The role of optical coherence tomography angiography in distinguishing ischemic versus non-ischemic central retinal vein occlusion
Introduction: To observe macular microvascular changes in patients with ischemic and non-ischemic central retinal vein occlusion (CRVO) by optical coherence tomography angiography (OCTA), and explore the value of OCTA in differentiating ischemic and non-ischemic CRVO. Methods: Cross sectional study. Fifty patients diagnosed as CRVO with macular edema were included. Macular edema in all patients were regressive after three consecutive anti-VEGF treatment. Patients were divided into ischemic anddoi:10.1186/s12886-022-02637-y fatcat:glfd2445xrg6vo26ye2kqdb54m
