观察巩膜扣带术后眼前节的远期改变及发生闭角性青光眼的危险性。方法 :应用超声生物显微镜 ( U BM)对 17例( 17眼 )裂孔源性视网膜脱离患者 ,在巩膜扣带手术前、手术后 1周及手术后 5个月的前房轴深、睫状体厚度、前房开放距离和小梁虹膜夹角进行检测。结果 :经术后 5个月随访 ,17例患者全部获得视网膜解剖复位。前房轴深 ,术后 1周与术前比明显变浅 ,术后 5个月与术前无显著性差异 ;睫状体厚度 ,术后 1周比术前明显增厚 ,术后 5个月与术前无显著性差异 ;前房角开放距离和小梁虹膜夹角 ,术后 1周比术前房角明显变窄 ,而术后 5个月与术前无显著性差异。结论 :巩膜扣带术对患眼的眼前节远期影响不明显 ,不会增加闭角性青光眼的危险性
To observe the long-term changes of anterior segment of scleral buckling and the risk of closed-angle glaucoma. Methods: Seventeen eyes (17 eyes) with retinal detachment were examined by UBM. Before anterior scleral buckling surgery, 1 week after surgery and 5 months after surgery, the anterior chamber depth, ciliary body Thickness, anterior chamber open distance and trabecular iris angle for detection. Results: After 5 months of follow-up, all 17 patients underwent retinal anatomic reduction. The axial depth of the anterior chamber was significantly lower than that before operation at 1 week and no significant difference at 5 months after operation. Preoperatively, the thickness of ciliary body was significantly thicker than preoperative one week after operation, Month and preoperative no significant difference; angle between the anterior chamber angle and the angle of trabecular Iris, 1 week after surgery significantly narrower than the preoperative anterior chamber angle, and postoperative 5 months and preoperative no significant difference. Conclusion: Scleral buckling has no obvious effect on the anterior segment and anterior segment of the affected eyes, and does not increase the risk of closed angle glaucoma
