准分子激光非穿透性小梁切除术治疗原发性青光眼的疗效评价

Clinical evaluation of the non-penetrating trabeculectomy in treating primary glaucoma by excimer laser

目的 :探讨准分子激光治疗原发性青光眼的效果。方法 :原发性青光眼 5 7眼 ,其中 5 0眼为宽角型青光眼 ,7眼为窄角型青光眼 ,用 Ar F准分子激光行巩膜瓣下巩膜造瘘。结果 :5 7眼术前平均眼压 33.2 3±18.45 mm Hg( 1mm Hg=0 .133 k Pa) ,术后平均 15 .2 3± 6 .45 m m Hg。治疗前后眼压差异具有显著性意义 ( P<0 .0 0 1)。 5眼窄角型青光眼术后眼压波动较大 ,其中 2眼改行小梁切除术。术后视力保持或改善占 87.7% ,前房深度、视野及视杯无明显改变 ,无 1例出现较严重的术后并发症。结论

Objective:To study the efficacy of primary glaucoma treatment by excimer laser.Methods:57 eyes of primary glaucoma among which 50 eyes were the wide-angle glaucoma, and 7 eyes were the narrow cleft glaucoma, were treated by sclerostomy under the scleral flap, using NIDEK-EC 5000 ArF excimer laser. Results:The average intraocular pressure of 57 eyes were (33.23±18.45)mmHg preoperatively, and were (15.23±6.45)mmHg postoperatively. The difference was statistically significant(P<0.001). The intraocular pressure of 5 eyes of narrow cleft glaucoma were abnormal, of which 2 eyes were retreated by trabeculectomy. The VA of 87.7% cases tended to be stabilized and improved slightly after laser treatemtn, and the anterior chamber depth, the visual field and the optic cup had no obvious changes. None showed serious postoperative complications. Conclusion:The non-penetrating trabeculectomy by excimer laser is an effective procedure for the treatment of primary open-angle glaucoma.
