青光眼小梁切除术后浅前房的原因及处理

目的:分析青光眼小梁切除术后浅前房的发生原因和处理方法。方法:对1556例1556眼施行小梁切除术的青光眼病例术后浅前房的原因进行分析,总结治疗方案。结果:术后发生浅前房148眼(9.51%)。滤过过强,结膜瓣渗漏,睫状体脉络膜脱离,睫状环阻滞性青光眼是术后浅前房发生的主要原因。术后相应处理后,147眼浅前房均恢复正常,1眼未恢复最终施行眼球摘除术。结论:青光眼小梁切除术术前、术后有效地控制眼压,术中保持前房深度,小梁切除大小适宜,巩膜瓣厚度均匀勿太薄,注意伤口缝线的松紧,术后观察眼压及前房的变化,及时对症处理并发症能取得较好效果。

Analysis on shallow anterior chamber formed after trabeculectomy in patients with glaucoma

·AIM:To analyze the causes for the formation of shallow anterior chamber after traheculectomy in patients with glaucoma and its treatment.·METHODS:Studies on the causes of shallow anterior chamber formed after trabeculectomy and its treatment were carried out in 1556 cases 1556 eyes with glaucoma during recent 7 years.·RESULTS:Shallow anterior chamber had been occurred in 148 eyes(9.51%)of 1556 eyes after the operation.The excessive drainage through filtration track,the loosening of suture,the leakage of chamber fluid and malignant glaucoma were the main causes for the formation of shallow anterior chamber formed after the operation.Under the corresponding treatment of complications after the operation,the shallow chamber in 147 eyes recovered to normal.·CONCLUSION:The effective control of intraocular pressure before and after the operation,keeping suitable depth of anterior chamber during the operation,master-ing the degree of tightness of suture at incision,careful observation on changes of intraocular pressure and anteri-or chamber and treatment of complications on time are key points for the prevention of shallow anterior chamber occurred in patients with glaucoma after trabeculectomy.·
