有关氩激光小梁成形术治疗青光眼的降压作用及何时选择此术以治疗开角型青光眼仍存在不同看法,有必要重新评估。重复的研究证明,激光小梁成形术可以降低眼压,且对大多数降压药物有附加作用。但其降压效应随时间延长而逐渐减弱。每年约有10%的病人不能继续控制其眼压。对激光与药物二者的治疗效果进行比较是很困难的事情。青光眼激光试验研究组提出了药物治疗和激光治疗方案,药物组第一步应用噻吗心安,尔后应用二特戊酰肾上腺素、低浓 Argon laser trabeculoplasty for the treatment of glaucoma hypotensive effect and when to choose this surgery to treat open-angle glaucoma still exist different views, it is necessary to re-evaluate. Repeated studies have shown that laser trabeculoplasty can reduce intraocular pressure and have an additional effect on most antihypertensive drugs. But its antihypertensive effect gradually weakened with time. About 10% of patients each year can not continue to control their intraocular pressure. It is very difficult to compare the therapeutic effects of both laser and medicine. Glaucoma laser research group proposed drug treatment and laser treatment programs, the first step in the drug group, timolol, and then use two-pivaloyl-epinephrine, low concentration
