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.

Clinical observation on combined operation for angle closure glaucoma with cataract

Objective To observe the effect of phacoemulsification combined with trabeculectomy for angle closure glaucoma with cataract.Methods 48 eys of 32 cases underwent phacoemulsification and implantation of posterior chamber foldable intraocular lens combined with trabeculectomy.The postoperative follow-up was 6 months.The visual acuity and intraocular pressure were analyzed.Results The preoperative intraocular pressure was 30-45 mmHg (1 mmHg =0.133 kPa).The postoperative intraocular pressure was 8-15 mmHg at the final visit.The corrected visual acuity was at ＞0.3 in 30 eyes (62.5％).Conclusion For angle closure glaucoma with cataract,phacoemulsification and implantation of posterior chamber foldable intraocular lens combined with trabeculectomy are safe and effective.
