Sixty glaucomatous eyes of 60 patients treated with laser trabeculoplasty as primary therapy were reviewed retrospectively. There were 42 eyes with capsular glaucoma and 18 with simple glaucoma. The mean prelaser intraocular pressure (IOP) was 35.2 (SD = 6.5) mmHg. Success was defined as IOP less than or equal to 22 mmHg without medication. The probability of success was 0.73 at 1 year, 0.66 at 2 years, 0.57 at 3 years, and 0.50 at 4 years. Three eyes experienced progressive visual field loss or disc damage in spite of an intraocular pressure below 22 mmHg without medication. High prelaser pressure and the severity of the visual field defects were significant predictors of treatment failure.
回顾性分析了60例接受激光小梁成形术作为主要治疗方法的青光眼患者的60只眼睛。其中42只眼睛患有囊膜性青光眼，18只患有单纯性青光眼。激光治疗前的平均眼压（IOP）为35.2（标准差=6.5）mmHg。成功定义为眼压在无需药物治疗的情况下小于或等于22 mmHg。1年时成功的概率为0.73，2年时为0.66，3年时为0.57，4年时为0.50。尽管有3只眼睛在无需药物治疗的情况下眼压低于22 mmHg，但仍出现了进行性视野缺损或视盘损害。激光治疗前的高眼压和视野缺损的严重程度是治疗失败的重要预测因素。
