方法：回顾性非随机临床病例研究。收集行巩膜扣带术治疗孔源性视网膜脱离的患者23例46眼的临床资料纳入研究，分析手术眼和对侧非手术眼术后3mo后复查时的最佳矫正视力、屈光度、眼压、前房深度、角膜内皮细胞计数、眼轴长度、眼球突出度等参数。

结果：本研究中所有患者行巩膜扣带术均一次性达到视网膜完全复位，无明显并发症及不良反应发生。至末次随访，与非手术眼相比，术眼屈光度、眼压、角膜内皮细胞计数、眼轴长度差异均无统计学意义(P>0.05)，最佳矫正视力、前房深度、眼球突出度差异均有统计学意义(P<0.05)。

结论：巩膜扣带术对孔源性视网膜脱离有效，其对眼球前房深度、眼球突出度均产生了一定程度的影响。

METHODS: This retrospective, non-randomized case-control study included 46 eyes of 23 patients who underwent SB for RRD. Best corrected visual acuity(BCVA), diopter, intraocular pressure(IOP), anterior chamber depth(ACD), the number of corneal endothelial cells, axial length and the degree of exophthalmos were evaluated in the operated eyes and the follow eyes postoperatively at 3mo.

RESULTS: After SB surgery, retina reattachment was achieved without any obvious complications or adverse reactions in all follow-up patients. Among all parameters, the significant decrease in BCVA of 0.15(LogMAR BCVA, P=0.007), in anterior chamber depth(ACD)of 0.29mm(P=0.011)and increase in the degree of exophthalmos of 0.54mm(P=0.047)were observed; the surgery-induced changes for other parameters, including diopter, IOP, counts of endothelial cells and axial length, were not significantly different(P>0.05).

CONCLUSION: SB is a good technique for repairing RRD. It brings SB-induced changes in ACD and the degree of exophthalmos.
