Phacoemulsification combined with trabeculectomy for angle-closure glaucoma with cataract

Objective To evaluate the clinical efficacy of phacoemulsification combined with trabeculectomy for the treatment of angle-closure glaucoma with cataract. Methods Thirty-eight eyes of 32 cases with angle-closure glaucoma with cataract were selected and retrospectively analyzed.All cases underwent phacoemulsification combined with trabeculectomy. The visual acuity, intraocular pressure, anterior chamber depth and complications in pre- and post-operation were observed. Results The follow-up time was 3-12 months. The average intraocular pressure were(25.8±3.9)mmHg(1 mmHg=0.133 kPa) and (14.2±4.1)mmHg in pre- and post-operation respectively, and the difference was statistically significant (t=12.637, P=0.000). The high intraocular pressure after operation occurred in 2 eyes, 1 eye intraocular pressure decreased to normal range after topical anti glaucoma drugs treatment for 2 days, and the other eye received trabeculectomy again. The visual acuity≥ 0.3 was in 11 eyes preoperatively and 36 eyes postoperatively .The difference was statistically significant (χ2=34.8500, P=0.0000). The anterior chamber depth in pre-and post-operation were (2.0±0.3) mm and (3.7±0.4) mm respectively, the difference was statistically significant between before and after treatment.(t=-20.959, P=0.000). Hyphema occurred in 3 eyes (7.9%), corneal edema in 5 eyes (13.2%), and anterior chamber inflammation in 5 eyes (13.2%), they were corrected after symptomatic treatment. No posterior capsular rupture and after-cataract happened. Conclusion Phacoemulsification combined with trabeculectomy for angle-closure glaucoma with cataract can effectively improve vision, reduce intraocular pressure and deepen the anterior chamber depth.
