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<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.
