青光眼小梁切除术后浅前房的分析

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

目的分析青光眼小梁切除术后浅前房的原因和处理方法。方法我院近5年来134例(150眼)青光眼患者,行小梁切除手术,术后观察浅前房的发生并给予相应处理。结果150眼中12眼发生浅前房,占8%。滤过道引流过畅,缝线松脱、房水渗漏,恶性青光眼是术后浅前房发生的主要原因。术后对并发症相应处理后,12眼发生浅前房均恢复正常。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,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。

Objective To analyze the causes for the formation of shallow anterior chamber after trabeculectomy in patients with glaucoma and its treatment. Method Studies on the causes of shallow anterior chamber formed after trabeculectomy and its treatment were carried out in 134 patients （ 150 eyes） with glaucoma admitted in this hospital during recent 5 years. Results Shallow anterior chamber had been occurred in 12 eyes （8%） of 150 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 anterior chamber in 12 eyes were all recovered to normal. Conclusion The effective control of intraocular pressure before and after the operation, keeping suitable depth of anterior chamber during the operation, mastering the degree of tightness of suture at incision, careful observation on changes of intraocular pressure and anterior chamber and treatment of complications on time are key points for the prevention of shallow anterior chamber occurred in patients with glaucoma after trabeculectomy.
