Correlation between cilioretinal artery and central visual impairment in patients with central retinal artery occlusion

Objective To investigate the correlation between cilioretinal artery and central visual impairment in patients with central retinal artery occlusion (CRAO).Methods A total of 32 CRAO patients (32 eyes) were selected,and results of central vision and fundus fluorescein angiography (FFA) were analyzed retrospectively.Correlation between cilioretinal arteries and degree of central visual acuity impairment was analyzed.Results In the 32 CRAO eyes,11 eyes were found with cilioretinal? arteries.Eye examination results showed that there were 10 eyes with mild visual impairment,9 eyes with moderate visual impairment and 13 eyes with severe visual impairment in the total 32 eyes.There were significant difference in the degrees of central visual impairment between CRAO patients with or without cilioretinal artery (P ＜ 0.05),and there was a significant correlation between cilioretinal artery and degree of central visual acuity impairment.Conclusion 34.4％ CRAO patients have cilioretinal artery,and cilioretinal artery in CRAO patients is associated with the degree of central visual acuity impairment.
