Nd:YAG激光虹膜周边切除术治疗原发性闭角型青光眼疗效评价

Nd: YAG Laser Peripheral Iridectomy in treating Primary Angle-closure Glaucoma

探讨激光虹膜周边切除术(Laser Peripheral Iridectomy,LPI)治疗原发性闭角型青光眼的临床疗效。应用标准视力表、非接触眼压计、超声生物显微镜Ultrasound Biomicroscopy,UBM)、前房角镜对63例97眼原发性闭角型青光眼(primary angle closure glaucoma,PACG)患者LPI前后观察。LPI术前术后最佳矫正视力不变或有所提高,但提高不明显。在原发性急性闭角型青光眼(acute primary angle closure glaucoma,Acute PACG)患者中,LPI术前术后眼压下降、中央及周边前房深度加深有统计学意义,前房房角较术前增宽;原发性慢性闭角型青光眼(chronic primary angle closure glaucoma,Chronic PACG)患者中,LPI术前术后眼压下降、中央及周边前房深度加深无统计学意义,前房房角增宽不明显。Nd:YAG激光虹膜周边切除术是治疗早期闭角型青光眼的有效手段,其术后疗效评价利于指导下一步治疗方案。但在慢性闭角型青光眼患者中,其术后疗效还有待探讨。

To evaluate the effection of Nd: YAG Laser Peripheral Iridectomy in treating Primary Angle-closure Glaucoma. Application of the standard eye chart,non-contact tonometer,ultrasound biological microscope,gonioscope in 63 cases 97 eyes with primary angle-closure glaucoma patients,to observe preoperative and the postoperative. LPI preoperative and postoperative best corrected visual acuity unchanged or improved,but the increase is not obvious. In patients with primary acute angle-closure glaucoma,LPI postoperative intraocular pressure drop,the central and peripheral anterior chamber depth degree burn was statistically significant,anterior chamber angle compared with preoperative broadening: In patients with primary chronic angle-closure glaucoma,LPI before the postoperative intraocular pressure drop,the central and peripheral anterior chamber depth deepening no statistical significance,widened anterior chamber angle is not significant. Nd: YAG LPI is an effective method for treatment of early angle-closure glaucoma,the postoperative curative effect evaluation to guide the next treatment. But in chronic angle-closure glaucoma patients,the postoperative efficacy remains to be discussed.
