作者根据Wise和Witter的方法,以氩激光作小梁成形术,治疗原发性开角型青光眼共53例(男30,女23)62眼(右34,左28)。大多数病例于180°范围内作50个光斑,少数病例以后对另180°作相同的治疗。光斑直径为50μm,曝光时间0.1秒,根据治疗反应,功率在0.8～1.4W之间变动。同一眼的不同部位反应不同,有时击射某一部位后未发现反应,而在另一部位则可看到满意的苍白斑甚至轻度水泡。对于色素很少的房角,激光击射之后的几秒钟内难以看到反应,为避免重复击射或遗漏这些部位,应于治疗过程中 According to Wise and Witter’s method, argon laser was used for trabeculoplasty in 53 eyes (34 male, 30 female) 62 eyes (right 34, left 28) for primary open-angle glaucoma. In most cases, 50 spots were made within 180 ° range, and in a few cases the same treatment was performed on the other 180 °. Spot diameter of 50μm, exposure time of 0.1 seconds, according to the treatment response, the power varies between 0.8 ~ 1.4W. Different parts of the same eye respond differently, and sometimes did not find a response after firing a site, while in another area you can see the satisfactory pale patch or even mild blisters. For the few pigmentation angle, the laser shot within a few seconds after hard to see the reaction, in order to avoid repeated shots or missing these parts should be in the course of treatment
