ABSTRACT
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
