Laser trabeculoplasty was carried out in one eye in each of 38 patients, 37 with chronic open-angle glaucoma and 1 with low-tension glaucoma, whose visual fields were deteriorating. The patients were randomly assigned to receive 10, 50 or 100 burns. Topical therapy was stopped for 1 week before treatment and for 1 week before reassessment 6 weeks later. Patients who received 50 or 100 burns had significant pressure reduction (p = 0.000). The difference in mean reduction between these two groups was not significant. Ten burns occasionally produced a reduction in pressure. Some patients may need fewer laser burns than are currently given, but most require the current treatment schedules.
对38例患者的单眼进行了激光小梁成形术，其中37例为慢性开角型青光眼，1例为低眼压性青光眼，这些患者的视野正在恶化。患者被随机分配接受10次、50次或100次烧灼。治疗前1周和6周后重新评估前1周停止局部治疗。接受50次或100次烧灼的患者眼压显著降低（p = 0.000）。这两组之间的平均降低差异不显著。10次烧灼偶尔会使眼压降低。一些患者可能需要的激光烧灼次数比目前的要少，但大多数患者需要目前的治疗方案。
