青光眼滤过术后浅前房的原因及处理

Causes and management of shallow anterior chamber after filtration surgery

目的分析青光眼滤过术后浅前房的原因及处理。方法对1999年9月～2003年9月395例(437眼)青光眼滤过术后浅前房者(44眼)进行回顾性分析。结果437眼滤过术后有44眼(10.07%)发生浅前房,其发生原因有:滤过过强(31/44,70.45%),滤过泡渗漏(7/44,15.91%),恶性青光眼(3/44,6.82%),脉络膜脱离(2/44,4.55%),迟发性脉络膜上腔出血(1/44,2.27%),其中,14眼(14/44,31.82%)需手术介入,经对症治疗后,前房均恢复正常。结论青光眼滤过术后浅前房较常见,大部分经非手术治疗可恢复正常,及时适当的手术治疗亦是治疗的关键。

Objective To analyse the causes and management ofshallow anterior chamber after filtration surgery. Methods 305 cases (437 eyes) from sep. 1999 to sep 2003 with glaucoma were treated with filtration surgery and shallow anterior chamber was found postoperatively. All cases were analysed retrospectively. Results 437 eyes were treated with filtration surgery, shallow anterior chamber was found in 44 eyes (10.07%). The causes included: excessive aqueous humor run off (31/44, 70.45%),leakage of filter bulb(7/44, 15.91%),malignant glaucoma (3/44, 6.82%), detachment of choroid(2/44, 4.55%),choroids chamber bleed (1/44, 2.27%). 14 cases (14/44, 31.82%) needed surgery. After proper management, shallow anterior chamber returned to normal depth in all cases. Conclusion Shallow anterior chamber was found usually after filtration surgery. Most of cases were returned without operation and proper operation was also key management.
