目的:观察巩膜扣带术后眼前房深度变化的情况。方法:选择行巩膜扣带术孔源性视网膜脱离25例(25眼),采用光学相干断层成像(OCT)及光学生物测量仪IOL-Master,分别于术前及术后1周、1个月、3个月、6个月、9个月和12个月进行检查,比较术前与术后眼前房深度及眼轴长度变化情况。结果:与术前比较,术后1周、1个月、3个月、6个月、9个月眼前房深度均显著减小(P<0.05),眼轴长度均显著增加(P<0.05);术后12个月前房深度变化差异不显著(P>0.05),但眼轴长度显著增加(P<0.05)。结论:巩膜扣带术后9个月内,眼前房显著变浅,同时眼轴显著增长。
Objective: To observe the changes of anterior chamber depth after scleral buckling operation. Methods: 25 cases (25 eyes) of rhegmatogenous retinal detachment underwent scleral buckling were selected. Optical coherence tomography (OCT) and optical bioassay instrument IOL-Master were used respectively in 1 week, 1 month and 1 month after operation , 3 months, 6 months, 9 months and 12 months. The changes of anterior chamber depth and axial length before and after operation were compared. Results: The anterior chamber depth was significantly reduced at 1 week, 1 month, 3 months, 6 months and 9 months after operation (P <0.05), and the axial length was significantly increased (P <0.05) ). There was no significant difference in atrial depth at 12 months after operation (P> 0.05), but axial length was significantly increased (P <0.05). Conclusions: Within 9 months after scleral buckling, the anterior chamber is significantly lighter and the axial length is significantly increased.
