摘要目的：观察透明晶状体超声乳化联合人工晶状体植入术治疗临床前期及先兆期原发性急性闭角型青光眼的安全性和有效性。方法对我院2010年3月至2014年6月临床前期及先兆期原发性闭角型青光眼37例(37眼),患眼眼轴≤22 mm,前房深度≤1.5 mm,行透明角膜切口晶状体超声乳化联合人工晶状体植入术。对部分前房角粘连者行前房角分离。术后随访6个月,分别于术前、术后7d、1个月、6个月行视力、眼压及前房深度检查。结果37例手术均顺利完成,术后无并发症,术后平均眼压(15.98±2.48)mmHg(1 mmHg=0.133 kPa)。17例(45.95%)术后视力较术前提高1~2行,20例(54.05%)术后视力与术前相同,无视力下降病例。前房深度较术前明显加深,前房角较术前明显加宽,前房角粘连范围明显减少。结论透明晶状体超声乳化联合人工晶状体植入术是治疗临床前期及先兆期原发性闭角型青光眼的一种安全、有效的方法。

abstractsObjective To observe the safety and effectiveness of clear lens phacoemulsification combined with intraocular lens ( IOL) implantation in treatment of preclinical stage or premonitory stage of the primary angle-closure glaucoma ( PACG ) . Methods The clinical data of 37 eyes of 37 cases with preclinical stage or premonitory stage of the primary angle-closure glaucoma in our hospital from March 2010 to June 2014 were collected. All patients with axial length≤22 mm and the anterior chamber depth ( ACD)≤1. 5 mm underwent phacoemulsification and IOL implantation through transparent corneal incision. During operation combined with goniosynechialysis in some patients with peripheral anterior synechiae. The follow-up period was 6 months. The visual acuity, intraocular pressure ( IOP) and ACD were observed before and after the surgery. Results All surgeries were performed smoothly with no postoperative complication occurred. The follow-up time was 6 months. The postoperative mean IOP was (15. 98 ± 2. 48) mmHg(1 mmHg=0. 133 kPa). Visual acuity after surgery was improved 1-2 lines in 17 eyes (45. 95%) and unchanged in 20 eyes (54. 05%). The loss of vision acuity had not occur. Compared with preoperation, the ACD was deepened significantly, the anterior chamber angle was widened obviously and the extent of peripheral anterior synechiae decreased obviously. Conclusion Clear lens phacoemulsification combined with IOL implantation is a safe and effective method for the treatment of preclinical stage or premonitory stage of the primary angle-closure glaucoma.
