视网膜中央动脉阻塞患者视网膜循环时间与中心视力损害的关系

目的探讨视网膜中央动脉阻塞（CRAO） 患者中心视力损害与病程、视网膜循环时间的关系。方法对99例99只眼CRAO患者的中心视力、发病病程、荧光素眼底血管造影 (FFA)检查视网膜循环时间等量化数值进行统计学分析。结果CRAO 患者不同病程时间(2~21 d)与中心视力损害程度差异无统计学意义（P＞0.05），视网膜循环时间中视网膜动脉荧光充盈间期与中心视力损害的关系差异有统计学意义（P＜0.05），臂 视网膜循环时间与中心视力损害差异无统计学意义（P＞0.05）。结论视网膜循环时间指标中视网膜动脉荧光充盈间期与中心视力损害相关，时间愈长视力损害愈重，值得关注。(中华眼底病杂志，2007，23：177-179)

Relationship between retinal circulation time and visual loss in patients with central retinal artery occlusion

ObjectiveTo investage the relationship among the visual loss, the disease course, and retinal circulation time in patients with central retinal artery occlusion (CRAO).MethodThe data about the central vision, disease course, and results of fundus fluorescein angiography (FFA) of 99 patients (99 eyes) with CRAO were statistically analyzed.ResultsBetween 2 days and 21 days after the occurrence of CRAO, the disease course didn't relate to the central visual loss (P>0.05). In the retinal circulation, a correlation was found between the time of fluorescein perfusion and the central visual loss (P<0.05) but not between the time of arm-retina circulation and the central visual loss (P>0.05).ConclusionIn the duration of retinal circulation, the time of fluorescein perfusion in retinal artery relates to the central visual loss; the longer the duration is, the worse the vision is.
