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 ALI in treatment of early- and middle-stage angle-closure glaucoma. It is a safe method for early examination after operation. LA: Chinese
