目的：探讨不同眼轴长度的闭角型青光眼及浅前房合并白内障患者发生晶状体悬韧带部分离断半脱位的概率是否有区别。

方法：回顾性分析2017-02/2019-03我院收治的闭角型青光眼和浅前房合并白内障患者，住院行白内障手术，分为两组，A组(眼轴<22mm)和B组(眼轴≥22mm)，采用超声生物显微镜(UBM)测量中央前房深度(ACD)，IOL Master测量眼轴长度(AL)，计算前房深度与眼轴长度的比值(ACD/AL)，分析UBM图像各个方位前房深度的一致性，白内障手术中记录晶状体悬韧带是否部分断裂，是否合并晶状体半脱位。

结果：B组患者晶状体悬韧带部分断裂的比率高于A组(8.46%±1.44% vs 7.56%±1.51%，P<0.05)。

结论：眼轴≥22mm时发生闭角型青光眼以及浅前房的患者行白内障手术，要关注晶状体悬韧带异常的可能。

METHODS: A retrospective analysis was performed,for patients with angle-closure glaucoma and patients of shallow anterior chamber with cataract admitted to our hospital from February 2017 to March 2019. The patients underwent cataract surgeries and were divided into two groups: Group A(visual axis <22mm)and Group B(visual axis ≥22mm). Central anterior chamber depth(ACD)was measured with ultrasound biomicroscopy(UBM); Axial length(AL, length of optic axis)was measured with IOL-Master; Calculation of the ratio of AC depth to axial length(ACD/AL)was performed. The consistency of the anterior chamber depth in all directions in UBM images was analyzed. In cataract surgeries, partial zonulysis with or without lens subluxation was recorded.

RESULTS: The result indicated that the rate of partial zonular dehiscence in group B was higher than that in group A(8.46%±1.44% vs 7.56%±1.51%, P<0.05).

CONCLUSION: When performing cataract surgery in patients of angle-closure glaucoma and shallow anterior chamber in group B, attention should be paid to the probability of zonular abnormality.
