摘要
本文报告用氩激光小梁成形术(ALT)治疗79例105眼开角型青光眼的4年疗效。总有效率78%,平均眼压下降10.04mmHg,4年内疗效稳定。全部病例均为最大耐受量药物治疗无效拟作滤过性手术者,ALT 术后83%病例在4年内可避免作滤过性手术。失败的23眼中有21眼在 ALT 术后半年内眼压回升,另2眼在第3年回升,18眼(17%)须作滤过性手术。ALT 术后42.9%的病例其用药种数减少。年岁较大(>60岁)、眼压<30mmHg、且病情较轻者则疗效较佳;严重损害的晚期青光眼(C/D≥0.9,视野<20°)对 ALT 的反应差,近60%在 ALT 术后仍须作滤过性手术。
79 patients(105 eyes)with uncontrol-led open angle glaucoma underwent argon laser tra- beculoplasty(ALT).The average pressure drop was 10.7 mmHg in 58 eyes at one year,10.1 mmHg in 35 eyes at two years,9.gmm Hg in 48 eyes at three ye-ars and 10.2 mmHg in 24 eyes at four years.The mean success rate was 78%,failures occured in the first six months in 21 of 23 eyes,the remaining eyes failed at three years,18 eyes(17%)required filtering surgery.Average medication scores varied little from year 1 through year 4 45 eyes(42.9%)were being treated with few medications after ALT.The results of ALT depend on the severity of glaucoma:the eyes with advanced disc damage(C/D≥0.9,vi-sual field<20°)had 59% rate of filtering surgery,while the eyes with C/D 0.6-0.8,visual field>20°at ALT had a filtering surgery rate of 3%.
