目的:探讨Nd:YAG激光(钇铷砷石榴石激光)周边多孔玻璃体前界膜切开在白内障超声乳化术后睫状环阻滞性青光眼中的应用效果。方法:用Nd:YAG激光对白内障超声乳化联合人工晶体植入术后,经常规药物治疗及中央后囊膜YAG激光切开无效的4例睫状环阻滞性青光眼患者,施行YAG激光周边多孔(三孔)玻璃体前界膜切开治疗。结果:4例患者经Nd:YAG激光周边多孔玻璃体前界膜切开后,当天眼内压均能降至接近正常范围,前房加深,角膜水肿大部分消退,短时间联合药物治疗一周后停用药物,4例患者眼压完全处于正常范围。随访7~34个月,所有病例眼压稳定,视力提高,未见持续眼前段炎性反应及后段葡萄膜炎等并发症。结论:Nd:YAG激光周边多孔玻璃体前界膜切开术简易安全,是治疗Phaco术后睫状环阻滞性青光眼的有效方法。
Objective: To investigate the effect of perforation of anterior porous vitreous membrane around Nd: YAG laser (yttrium rubidium arsenate garnet laser) in ciliary loop-locked glaucoma after phacoemulsification. Methods: After cataract phacoemulsification combined with intraocular lens implantation with Nd: YAG laser, 4 patients with ciliary retarded glaucoma who were treated by conventional medical therapy and central posterior capsular YAG laser incision were treated with YAG laser peripheral porous (Three holes) vitreous anterior membrane incision and treatment. Results: Four cases of patients with intraocular pressure of the vitreous body after Nd: YAG laser incision were able to reduce their intraocular pressure to near the normal range on the day. The anterior chamber deepened and corneal edema mostly subsided. After a short period of one week of combined drug treatment With drugs, 4 patients with intraocular pressure completely in the normal range. All cases were followed up for 7 to 34 months. All cases had stable intraocular pressure (IOP) and improved visual acuity. No persistent anterior segment inflammatory reaction and complications such as uveitis were observed. Conclusion: Porous vitrectomy is an easy and safe procedure for peri-vitrectomy of Nd: YAG laser. It is an effective method for the treatment of cycloplegic glaucoma after Phaco.
