AIM:To investigate whether there is a difference in the probability of partial zonular dehiscence and subluxation in patients with angle-closure glaucoma and shallow anterior chamber combined with cataract. <p>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.<p>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% <i>vs</i> 7.56%±1.51%, <i>P</i><0.05). <p>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.
