Abstract:
Objective To select the risk factors and focus on the pathogenesis of anterior ischemic optic neuropathy (AION) after cataract surgery.Methods A retrospective review of all patients with phacoemulsification surgery referred to the Ophthalmology Divisions,the First Affiliated Hospital,Zhengzhou University,from September 1,2010 to September 1,2016 was performed.Eligible patients were 11 206 cases(13 320 eyes),30 cases (30 eyes) were complicated with AION after cataract surgery (AION group),and 90 cases (90 eyes) were selected as control group according to the ratio of 1 ∶ 3 by random sequence.Factors of small cup disc ratios,previous surgery history,cardiac disease,diabetes,hypertension,hyperlipemia,smoking,carotid disease and intraocular pressure (IOP) were collected,x2 test,Logistic regression and t test were performed to analyze risk factors for AION.Results Small cup-disc ratios,diabetes,hypertension,hyperlipemia,carotid disease were influencing factors of AION after cataract surgery.Hyperlipemia and carotid disease were risk factors of AION after cataract surgery.There was no significant difference in preoperative intraocular pressure between two groups(all P ＞ 0.05).The intraocular pressure at postoperative 1 day and 7 days in AION group were higher than those in control group (all P ＜ 0.05).Conclusion Hyperlipemia and carotid artery disease are risk factors for AION after cataract surgery,and high intraocular pressure may be the inductive factor of AION.
