Abstract: Objective To observe the optic disc perfusion in anterior ischemic optic neuropathy (AION) patients.Methods Forty eyes of 40 AION patients and 30 eyes of 30 normal subjects were included.The stage of the diseases was defined based on the course of the disease,including acute stage (less than 3 weeks) and recovery stage (more than 3 months).Optic disc blood flow area,outer vascular density and blood flow index were measured by optical coherence tomography angiography in all the subjects.Optic disc perfusion was observed in acute and recovery stage of disease.Results The optic disc blood flow area,outer vascular density and blood flow index were decreased of AION eyes in acute stage compared with the normal subjects,the difference was statistically significant (P＜0.05);while the optic disc blood flow area,outer vascular density and blood flow index of AION eyes in the recovery stage showed no significant difference compared with normal subjects (P＞0.05).Conclusion Disc perfusion is reduced in AION at the acute stage,but recovered at the recovery stage.
