从1973年许多学者试图以高强度的激光使小梁网穿孔治疗开角型青光眼。Krasnov首先以调红宝石激光在小梁网上产生孔洞,但是降眼压作用是暂时的,需要反复治疗。Teichmann等用氩激光穿通小梁网,但未能获得与Schlemm氏管间持续的沟通。他们认为氩激光不适于小梁穿刺术。Ticho和Zauberman在小梁网的四分之一园周上作50个低强度的击射点,使眼压有一定程度的下降。Wickham和Worthen在房角的两个钟点范围内用不同强度的氩激光进行治疗,平均眼压下降10.3mmHg,治疗后2年,有20%眼压低于20mmHg。于1974年Gaasterland和Kupfer在猴眼用高强度的氩激光反复击射房角,造成了实验性青光眼。至1976年由于激光
Since 1973, many scholars have tried to perforate the trabecular meshwork with high-intensity laser to treat open-angle glaucoma. Krasnov first used a ruby laser to create holes in the trabecular meshwork, but the IOP reduction was temporary and required repeated treatment. Teichmann and other argon laser through the trabecular meshwork, but failed to obtain sustained communication with the Schlemm’s tube. They think argon laser is not suitable for trabecular surgery. Ticho and Zauberman made 50 low-intensity shots on a quarter of the circumference of the trabecular meshwork, causing some reduction in IOP. Wickham and Worthen were treated with different intensities of argon laser for a two-hour period over the corner of the room, with an average IOP reduction of 10.3 mmHg and a 20% IOP lower than 20 mmHg 2 years after treatment. In 1974, Gaasterland and Kupfer repeatedly fired the angle of the horn with a high-intensity argon laser in the monkey’s eye, causing experimental glaucoma. By 1976 due to laser
