To assess whether the axial length is a local risk factor in central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO).
The axial lengths of affected and fellow eyes of 19 patients with CRVO and 27 with BRVO and of their controls were measured with A-scan ultrasonography. The control group consisted of 17 individuals for CRVO and 25 for BRVO matched in age, sex and the prevalence of hypertension and diabetes in patient groups. The results of measurements in affected, unaffected and control eyes were compared.
The mean axial length was different among the affected and unaffected eyes in patients with CRVO and their controls (P < .05). The affected eyes had significantly shorter axial length compared to the fellow and control eyes (P < .01 and P < .01, respectively). In the BRVO group, the mean axial length did not differ among affected, unaffected and control eyes (P > .05).
Our study demonstrates a significantly shorter axial length in eyes with CRVO and not significantly shorter axial length in those with BRVO. The shorter axial length could be an additional risk factor in the pathogenesis of CRVO.
评估眼轴长度是否为视网膜中央静脉阻塞（CRVO）和视网膜分支静脉阻塞（BRVO）的局部危险因素。
采用A超超声检查测量19例CRVO患者、27例BRVO患者患眼及其对侧眼以及对照组的眼轴长度。对照组由17例CRVO患者和25例BRVO患者组成，在年龄、性别以及患者组中高血压和糖尿病患病率方面进行匹配。比较患眼、未患眼和对照眼的测量结果。
CRVO患者患眼与未患眼及其对照组之间的平均眼轴长度存在差异（P < 0.05）。患眼的眼轴长度明显短于对侧眼和对照眼（分别为P < 0.01和P < 0.01）。在BRVO组中，患眼、未患眼和对照眼的平均眼轴长度无差异（P > 0.05）。
我们的研究表明，CRVO患者的患眼眼轴长度明显较短，而BRVO患者的患眼眼轴长度无明显缩短。较短的眼轴长度可能是CRVO发病机制中的一个额外危险因素。
