为分析开角型青光眼在氩激光小梁成形术（ＡＬＴ）后的眼压变化情况，并探讨与青光眼种类、随访时间、患者年龄的关系。对２１例（３５眼）开角型青光眼患者，经药物治疗后眼压仍处在２３～３５ｍｍＨｇ范围内，行小梁后区１８０度或３６０度氩激光光凝治疗。术后随访１．５～６个月。结果：眼压控制率时间呈偏心性正态曲线分布，最佳控制效果在术后四周（控制率８４．７％），以后眼压呈上升的趋势，半年眼压控制率为５９．３％；原发性青光眼疗效显著高于继发性组（Ｐ＜０．０５）；４０岁以上年龄组疗效明显好于４０岁以下组（Ｐ＜０．０１），没有明显的并发症。结论：ＡＬＴ对药物控制不理想、但在３５ｍｍＨｇ以下的开角型青光眼可作为首选的降压治疗方法
To analyze the change of intraocular pressure (IOP) of open-angle glaucoma after argon laser trabeculoplasty (ALT), and to explore the relationship with glaucoma type, follow-up time and patient’s age. In 21 patients (35 eyes) with open-angle glaucoma, the intraocular pressure was still in the range of 23-35 mmHg after the drug treatment. The posterior trabecular area was treated by 180 or 360 degree argon laser photocoagulation. Follow-up 1.5 ~ 6 months after operation. Results: The intraocular pressure control time was eccentric normal curve distribution, the best control effect in the postoperative four weeks (control rate 84.7%), after the intraocular pressure showed an upward trend, half a year intraocular pressure control rate was 59.3% The efficacy of primary glaucoma was significantly higher than that of the secondary group (P <0.05). The efficacy of the group over 40 years old was significantly better than that of the group under 40 years old (P <0.01). There was no obvious complication. Conclusion: ALT is not ideal for drug control, but open angle glaucoma below 35mmHg may be the preferred antihypertensive treatment
