摘　　要：目的:采用Pentacam眼前节分析系统观察闭角型青光眼超声乳化手术前后前房结构变化.验证超声乳化晶体吸除术联合人工晶体植入术对于治疗早中期原发性闭角型青光眼的有效性。方法:早中期闭角型青光眼42例44眼,超声乳化术前及术后1d、1周、3个月用Pentacam测量中央前房深度、前房容积、前房角变化,同时于术前及术后3个月使用A超测量中央前房深度,并与Pentacam测量结果进行比较。结果:Pentacam能清晰显示手术前后眼前段组织三维结构,术后平均前房容积、平均前房深度、前房角较术前明显增加,术后眼压降低,视力提高(P<0.01)。Pentacam前房深度的测量结果及离散系数均小于A超(P<0.01)。结论:Pentacam眼前节分析系统能直观定量反映早中期闭角型青光眼超声乳化人工晶体植入术后前房深度、前房容积及前房角较术前明显增加,是术后早期安全的检查手段。Objective：To observe the changes in the anatomy of anterior segment before and after phacoemulsification for treatment of angle-closure glaucoma by Pentacam system, so as to assess the efficacy of phacoemulsification combined with artificial lens implantation（ALI） in treatment of early- and middle-stage angle-closure glaucoma. Methods： Forty-two patients with early- and middle-stage angle-closure glaucoma（44 eyes） were included in the present study. The central anterior chamber depth,anterior chamber volume and peripheral anterior chamber angle were examined by Pentacam system pre-operatively and 1 day, 1 week and 3 months post-operatively. Meanwhile, A ultrasound was used to examine the anterior chamber depth before and 3 months after operation,and the results were compared with those by Pentacam system. Results： Pentacam system could clearly demonstrate the 3-dimensional structures of the anterior eye segment before and after operation. The central anterior chamber depth,anterior chamber volume and anterior chamber angle were increased significantly after operation （P 〈 0. 01 ）. the intraocular pressure was significantly decreased（P〈0.01） ; and the visual acuity was improved（P〈0.01）. The values of central anterior chamber depth and the dispersion coefficient obtained by Pentacam were smaller than those by A ultrasound. Conclusion： Pentacam system can directly demonstrate the increase of anterior chamber depth, anterior chamber volume, and anterior chamber angle after phacoemulsification combined with ALl in treatment of early- and middle-stage angle-closure glaucoma. It is a safe method for early examination after operation.
