目的：探讨原发性青光眼小梁切除术后滤过泡的形态功能与眼压控制的关系。方法：随机选择１９９６年５月～１９９９年４月行巩膜板层下小梁切除术治疗的青光眼患者５８例（共７９眼），对滤过泡的形态和功能等情况进行分析。结果： Ⅰ型滤过泡占７２．１５％，平均眼压１７．４６ｍｍＨｇ；Ⅰ型滤过泡占１０．１３％，平均眼压９．８１ｍｍＨｇ。Ⅲ型滤过泡占１２．６６％，平均眼压２５．２５ｍｍＨｇ；Ⅳ型滤过泡占 ５．０６％，平均眼压２９．７５ｍｍＨｇ。结论：滤过泡的功能受青光眼的类型，严重程度，切口处的药物处理，手术技巧和病人个体差异等多种因素影响。
Objective: To investigate the relationship between the morphological function of filtration bleb and the control of intraocular pressure after trabeculectomy of primary glaucoma. Methods: Fifty-eight patients (79 eyes) with traumatic glaucoma under scleral lamina were randomly selected from May 1996 to April 1999 to analyze the morphology and function of filtration bleb. Results: Type I bleb accounted for 72.15% with an average IOP of 17.46mmHg. Type I bleb accounted for 10.13% with an average IOP of 9.81mmHg. Ⅲ filtration bleb accounted for 12.66%, the average IOP was 25.25mmHg; type Ⅳ bleb accounted for 5.06%, the average IOP was 29.75mmHg. Conclusion: The function of filtering bleb is affected by many factors such as the type and severity of glaucoma, drug treatment at the incision, surgical skills and individual patient differences.
