Abstract

Background:  The aim was to evaluate anterior segment parameters in patients with pseudoexfoliation syndrome (PXS) or pseudoexfoliative glaucoma (PXG) with the Pentacam-Scheimpflug imaging system.

Methods:  Eighty eyes of 53 patients with PXS (Group 1), 80 eyes of 57 patients with PXG (Group 2) and 80 eyes of 45 control cases (Group 3) were included in the study. Anterior chamber depth, volume (ACV), angle (ACA) width, central corneal thickness (CCT), central 3.0, 5.0 and 7.0 mm corneal volumes and pupil diameters were compared between groups.

Results:  Although anterior chamber depths in the PXG group were significantly lower than the control group (p < 0.05), there was no statistically significant difference between the PXS group and the control group in means of anterior chamber depth values (p > 0.05). There were no statistically significant differences among PXS, PXG and the control group in mean values of ACV, ACA width, CCT, pupil diameters and central 3.0, 5.0 and 7.0 mm corneal volume (p > 0.05).

Conclusions:  The anterior chamber depths of PXG patients were lower than those of healthy individuals. Although the difference in anterior chamber depth between PXG patients and normal patients was statistically significant, this finding is unlikely to be of clinical significance. The anterior chamber depths of PXS patients were similar to those of healthy individuals. There were no significant differences in the means of ACV, ACA width, CCT, pupil diameter and corneal volume values on central 3.0, 5.0 and 7.0 mm among patients with PXS, PXG and healthy individuals.
