Clinical Features and Functional Visual Recovery of Patients with Central Retinal Artery Occlusion Treated with Intra-Arterial Thrombolysis:A Single-Center Study
Objective To investigate the clinical characteristics and functional visual recovery of patients with central retinal artery occlusion(CRAO)treated with intra-arterial thrombolysis(IAT).Methods The non-arteriotic CRAO patients admitted to the Department of Neurology and Neuro-ophthalmology of the First Affiliated Hospital of Northwest University from January 2018 to August 2023 were included.They were divided into IAT group and non-IAT group according to whether IAT was performed after admission.Functional vision is defined as visual acuity ≥20/100.The clinical features and functional visual recovery at different time periods(admission,discharge and 1 month after discharge)were compared and analyzed between the two groups.Results A total of 131 patients(131 eyes)with non-arteriotic CRAO were included,including 93 males(71.0％)with a mean age of(61.6±12.6)years.There were 57 patients(43.5％)in IAT group and 74 patients(56.5％)in non-IAT group.Compared with patients in non-IAT group,patients in IAT group had younger age[(58.4±12.5)years vs.(64.1±12.2)years,P=0.011],lower proportion of stroke history[10(17.5％)vs.25(33.8％),P=0.037],shorter time from onset to visit[10.0(6.0-24.0)h vs.55.0(20.2-162.0)h,P＜0.001],higher proportion of onset after awakening[26(45.6％)vs.15(20.3％),P=0.002]and better internal carotid artery status on the affected side(none-stenosis∶mild stenosis∶moderate-severe stenosis∶occlusion=41∶7∶7∶2 vs.32∶11∶21∶10,P=0.006).The proportion of functional vision at 1 month after discharge was higher in IAT group than that in non-IAT group[25(43.9％)vs.18(24.3％),P=0.018],but there was no statistically significant difference in other time periods(admission and discharge)(P＞0.05).Multivariate logistic regression analysis showed that the functional vision of CRAO patients in the IAT group at 1 month after discharge was significantly improved compared with those in the non-IAT group(OR 3.24,95％CI 1.08-9.69,P=0.036).In the IAT group,ophthalmic artery spasm occurred in 2 cases(3.5％),skin bleeding at the puncture site in 2 cases(3.5％),and new cerebral embolism(all asymptomatic embolism)occurred in 4 cases(7.0％).Conclusions Some clinical features of CRAO patients who were treated with or without IAT were different.IAT can significantly improve the functional vision of CRAO patients at 1 month after discharge,and the surgical safety is good.This suggests that clinicians should pay more attention to IAT in CRAO patients in order to improve their visual function.
