睫状视网膜动脉与视网膜中央动脉阻塞患者中心视力损害的相关性分析

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

目的探讨睫状视网膜动脉与视网膜中央动脉阻塞(CRAO)中心视力损害的相关性。方法选取CRAO患者32例(32只眼),回顾性分析所有患者的中心视力与荧光素眼底血管造影(FFA)检查结果,探讨睫状视网膜动脉与中心视力损害程度的相关性。结果 32只患眼中,11只眼有睫状视网膜动脉。中心视力检查结果显示,在32只眼中,轻度、中度及重度视力损害分别为10、9和13只眼。有睫状视网膜动脉的CRAO患者和无睫状视网膜动脉的CRAO患者各个程度的中心视力损害比较均有显著差异(P<0.05),且睫状视网膜动脉同CRAO患者患眼的中心视力损害程度具有显著相关性。结论 34.4%的CRAO患者存在睫状视网膜动脉,且睫状视网膜动脉同CRAO患者的中心视力损害程度具有显著相关性。

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 angiogra- phy （FFA） were analyzed retrospectively. Correlation between cilioretinal arteries and degree of cen- tral 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 impair- ment, 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 pa- tients 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.
