目的:探讨小梁切除术后浅前房发生原因及处理方法。方法:对不同类型青光眼68例72眼小梁切除术后浅前房20眼进行原因分析及治疗效果观察统计。结果:本组72只眼中术后发生浅前房者8只眼,其中浅Ⅰ度6只眼,浅Ⅱ度1只眼,浅Ⅲ度1只眼。发生手术后1～3d的有3只眼,术后4～7d的有5只眼,发生后即给予对症治疗,7只眼恢复正常,1只眼由浅Ⅲ变为浅Ⅰ。经3～24个月内随访,眼压控制理想,结膜滤过弥散或局限,仅1例有明显的虹膜后粘连,其余病例均未出现其他并发症。结论:小梁切除术降压效果肯定,但浅前房发生率高,注意术前降眼压,减轻炎症反应,术中操作准确,可减少浅前房发生。
Objective: To investigate the causes and treatment of shallow anterior chamber after trabeculectomy. Methods: 68 cases of different types of glaucoma in 72 eyes after trabeculectomy shallow anterior chamber of 20 cases were analyzed and the treatment effect statistics. Results: In the group of 72 eyes, there were 8 eyes of shallow anterior chamber, of which 6 were shallow Ⅰ, 1 shallow Ⅱ and 1 shallow Ⅲ. There were 3 eyes 1 ~ 3 days after operation and 5 eyes 4 ~ 7 days after operation. Symptomatic treatment was given after the operation, 7 eyes returned to normal, and 1 eye changed from shallow Ⅲ to superficial Ⅰ. After 3 to 24 months follow-up, intraocular pressure control ideal, conjunctival filtration dispersion or limitations, only 1 case had significant post-iris adhesions, the rest of the cases were no other complications. Conclusion: The effect of trabeculectomy on blood pressure reduction is definite, but the incidence of shallow anterior chamber is high. Pay attention to preoperative intraocular pressure reduction and reduce inflammatory reaction. Accurate intraoperative operation can reduce the occurrence of shallow anterior chamber.
