闭角型青光眼(ACG)患者作Nd:YAG激光周边虹膜切开术已被公认。虽然,激光虹膜切开比手术要安全些,但也有一定的并发症。重要的并发症之一是激光后眼压急剧升高,对已经有视乳头损害的慢性闭角型青光眼病例,突然和没有防备的眼压急剧升高,可导致进一步对视乳头的损害。有必要认识这些因素,有助于预测激光后的经过,使有足够时间进行预防措施。作者等对激光前眼压、房角闭塞类型、激光能量和术时出血与虹膜炎的并发症作了前瞻性研究,以便确定Nd:YAG激光虹膜切开术后眼压升高,这些 Closed-loop glaucoma (ACG) patients with Nd: YAG laser peripheral iridectomy has been recognized. Although laser iridectomy is safer than surgery, there are certain complications. One of the major complications is a dramatic rise in post-laser IOP. Sudden and unprovoked intraocular pressure (IOP) increases dramatically in cases of chronic angle-closure glaucoma that already have optic nerve damage, leading to further damage to the optic nerve. It is important to understand these factors to help predict what happens after the laser so that enough time is available to prevent it. The authors prospectively studied the complications of laser anterior chamber pressure, type of occlusion, laser energy, and postoperative bleeding and iritis, in order to identify elevated intraocular pressure after Nd: YAG laser iridectomy
