激光用于青光眼的治疗已有近35a的历史。近年来,选择性激光小梁成形术(SLT)以其安全、有效降眼压、并发症少等优点逐渐成为开角型青光眼的首选治疗。选择性激光小梁成形术是治疗开角型青光眼的一种新型激光手术,它应用倍频Q-开关、波长532nm的Nd:YAG激光,选择性作用于色素性小梁组织达到降低眼压目的。与氩激光小梁成形术(argonlasertrabeculoplasty,ALT)相比,两者降眼压效果相似,但是相对于ALT对小梁网的凝固性损伤,SLT选择性作用于色素性小梁细胞,无凝固性损伤,对小梁网组织轻微破坏,是一种安全且可重复治疗的手段。

·Lasers have been used to treat glaucoma for nearly 35 years.Recently,selective laser trabeculoplasty(SLT)as primary therapy for open angle glaucoma(OAG)is more safe and effective.SLT is a new method to reduce intraocular pressure in eyes with OAG.This method of treatment uses a frequency doubled,Q-switched YAG laser rather than an argon wavelength.This form of laser produces a very brief burst of laser energy that targets the melanin content of meshwork cells and selectively ablates them.This is in contrast to the thermal photocoagulation effect of argon treatment,which caused local and collateral damage.·
