对56例71只原发性早期急性及慢性青光眼进行前瞻性研究随机分组,分别施行Nd:YAG激光虹膜切除术或周边虹膜切除术,术后随访1～3年,说明两种手术1年、2年及3年成功率(眼压≤2.8kPa)、术后眼压值、C值及CT值均无显著性差异。两种手术术后房角镜检查均各有82%的患者房角增宽到N2至W角水平,虽然下方房角小梁区的色素沉着,激光组(46.4%)远高于手术组(8.0%),但色素沉着对眼压控制率无明显影响。 Fifty-six cases of 71 primary acute and chronic primary glaucoma were prospectively randomized to Nd: YAG laser iridotomy or peripheral iridotomy. The patients were followed up for 1 to 3 years. The results showed that the two procedures were 1 year, Two-year and three-year success rate (intraocular pressure ≤ 2.8kPa), postoperative intraocular pressure, C and CT values ​​were not significantly different. 82% of the patients in each of the two postoperative gonioscopic examinations widened to a N2 to W angle. Although the lower trabecular area was hyperpigmented, the laser group (46.4%) was much higher than the surgical group ( 8.0%), but no significant effect of pigmentation on IOP.
