视网膜静脉阻塞与眼轴关系研究

Retinal Vein Occlusion and Axial Length

目的探讨视网膜静脉阻塞与眼轴的关系。方法应用A型超声仪对16例中央静脉阻塞(CRVO)和19例分枝静脉阻塞(BRVO)眼轴进行测量,两对照组分别同两病例组年龄和性别相配,例数相等。结果CRVO组阻塞眼轴长显著低于对侧眼及正常对照眼(P<0.01)。BRVO组阻塞眼轴长与对侧眼及正常对照眼比较差异无显著性(P>0.05)。结论短眼轴是CRVO的危险因素。

Objective To study the relationship between retinal vein occlusion and axial length. Methods The axial lengths of affected and fellow eyes of 16 patients with CRVO and 19 with BRVO and of their controls were measured with A-scan ultrasonography. The control group consisted of 16 individuals for CRVO and 19 for BRVO matched in age and sex. Results In the CRVO group, the affected eyes had significantly shorter axial length compared to the fellow and control eyes （P 〈 0.01）, The mean axial length did not differ among the affected, unaffected eyes in patients with BRVO and the eyes in controls （P 〉 0.05）. Conclusion The shorter axial length is a risk factor to CRVO.
