目的：评价激光周边虹膜切除术和小梁切除术在治疗早期慢性闭角型青光眼的远期疗效。
方法：对98例102眼早期慢性闭角型青光眼患者，随机分为A组50例54眼行周边虹膜切除术和B组48例48眼行小梁切除术。追踪观察3～8a，比较两组术后视力、眼压、前房角、视野及杯/盘比值的变化情况。
结果：A组视力下降24眼，眼压>21mmHg(1mmHg=0.133kPa)者22眼，房角粘连>180° 21眼，视野缩小21眼，C/D扩大21眼； B组依次为10眼，5眼，4眼，4眼和4眼，两组比较差异有统计学意义(P<0.05)。
结论：早期慢性闭角型青光眼手术治疗，可取得良好的疗效，远期疗效小梁切除术明显优于虹膜周边切除术。

[Abstract]
AIM: To evaluate the long-term effects of laser peripheral iridectomy(LPI)and trabeculectomy in treating early chronic angle-closure glaucoma.
METHODS: Ninety-eight patients(102 eyes)with early chronic primary angle-closure glaucoma were randomly divided into two groups. Group A of 50 patients(54 eyes)was treated with LPI and group B of 48 patients(48 eyes)with trabeculectomy. After 3-8y of follow-up observation, comparison would be made from the perspectives of postoperative eyesight, intraocular pressure, anterior chamber angle, visual field and cup/disc ratio(C/D).
RESULTS: In group A, 24 eyes with eyesight declining, 22 eyes with theintraocular pressure >21mmHg(1mmHg=0.133kPa), 21 eyes with chamber angle synechia >180°, 21 eyes with visual field narrowed, 21 eyes with C/D ratio enlarged. The results of group B for the same items were 10, 5, 4, 4, 4 eyes respectively. The comparative difference was statistically significant(P<0.05).
CONCLUSION: Good effects will be achieved for early-stage chronic angle-closure glaucoma with surgical method.Trabeculectomy is obviously better than LPI for the long-term effects.
