青光眼滤过术后滤泡并发症及其处理

目的 探讨青光眼滤过术后滤泡并发症及其处理效果。方法 回顾性分析我院青光眼滤过术后滤泡并发症情况，随访时间从2000年2月到2002年4月，观察记录并分析并发症发生情况和预后效果。结果 55例(68眼)青光眼患者，小梁切除术后发生滤过泡疤痕11例，滤过泡渗漏2例，滤过泡感染1例，包裹性囊状滤过泡1眼，巨大薄壁滤过泡1眼。其中7例早期疤痕性滤过泡患者经处理后有5例眼压得以控制，4例晚期疤痕性滤过泡患者仅1例加用抗青光眼药物后眼压可维持于正常水平；滤泡渗漏和滤泡感染患者经处理完全治愈；包裹性囊状滤过泡及巨大薄壁滤过泡也得到控制。结论 青光眼滤过手术后会出现各种滤过泡并发症，早期及时正确处理成功率高，可避免造成严重后果。

A clinical analysis on the complication and treatment of filtering bleb after glaucoma filtration surgery

Objective To review the complications of filtering bleb from eyes undergoing the glaucoma filtration surgery and evaluate the efficiency f the treatment.Methods From February 2000 to pril 2002 all patients after trabeculectomy were retrospectively reviewed.The complication of filtering bleb and its reason were analyzed.The treatment causing these complications were also discussed.Results 55 cases(68 eyes)of glaucoma were operated by trabeculectomy.Filtering bleb scarring occurred in 11 eyes;Bleb leak occurred in 2 eyes;Infected bleb occurred in 1 case;Encapsulated bleb1 case,and oversized bleb 1 case.Patients were enrolled on a consecutive basis and prospectively followed up.Standard trabeculectomies were performed.During the first two years,five of 7 cases of early onset bleb scarring had been controlled in IOP,however,only one of 4 cases late onset bleb scarring remained normal IOP level merely when treated with glaucoma drugs.Filtering bleb leak and blebitis were cured after treatment.Likewise,encapsulated bleb and oversized bleb were also controlled.Conclusions There are numerous early and later bleb related problems following filtering surgery.Serious results would be avoided if treated promptly and precisely.
