眼球轴长与视网膜中央静脉阻塞的关系(英文)

Relationship between ocular axial length and central retinal vein occlusion

目的 探讨眼球轴长与视网膜中央静脉阻塞 (centralretinalveinocclusion ,CRVO)的相关关系。方法 31例CRVO患者和 6 2例选自白内障摘除、而年龄和性别与本组CRVO患者相匹配的对照病例 ,做了轴长的对比研究 ,轴长应用A型超声测量。结果 CRVO组患眼平均轴长 (2 2 .5 9± 0 .6 4 )mm ,对侧眼平均轴长(2 2 .98± 0 .94 )mm ;经统计学处理 ,差异无显著性 (t=1.92 ,P >0 .0 5 )。对照组右眼平均轴长 (2 3.6 1± 0 .6 2 )mm ,左眼平均轴长 (2 3.73± 0 .83)mm ,左右眼比较 ,差异无显著性 (t=1.95 ,P >0 .0 5 )。CRVO组患眼轴长与对照组比较 ,差异有显著性 (t=4 .0 1,P <0 .0 1)。结论 眼球轴长偏短是与CRVO发病相关的危险因素之一。

Objective:To evaluate the relationship between ocular axial length and central retinal vein occlusion(CRVO).Methods:A case-control study of axial length was performed on 31 patients with CRVO and 62 age and sex-matched control patients selected from a list of subjects who had undergone cataract extraction.Axial length measurement was taken with A-scan ultrasonography.Results:The mean axial length of the affected and the fellow eyes in CRVO group did not differ statistically(t=1.92,P>0.05).The mean axial length in the right eyes of the control group was (23.61±0.62)mm,and that of the left eyes was (23.73 ±0.83)mm, the difference being not statistically significant (t=1.95, P>0.05).The difference in axial length between the eyes with CRVO and the eyes in control group was statistically significant(t=4.01, P<0.01).Conclusions:Short axial length is one of the risk factors for central retinal vein occlusion.
