Abstract

PURPOSE: To evaluate the effects of prostaglandin analogues on the corneal thickness of patients with primary open-angle glaucoma (POAG) or normal tension glaucoma (NTG).
METHODS
This study included 130 eyes of 65 patients who were diagnosed with POAG or NTG. All patients were divided into two groups; one group received prostaglandin analogues, while the other group received alternative ocular hypotensive eyedrops. Corneal thickness, best corrected visual acuity, and flare in the anterior chamber were measured and compared before treatment and at least 24 months (mean: 27 months) after treatment.
RESULTS
The mean decrease in corneal thickness was statistically significant in the group using prostaglandin analogues, but not in the control group. Among the various prostaglandin analogues used, travoprost and latanoprost decreased mean corneal thickness, but bimatoprost had no effect. Best corrected visual acuity, refraction power, and flare in the anterior chamber did not change significantly in either group of patients when ocular hypotensive eyedrops were used.
CONCLUSIONS
Prostaglandin analogues lower intraocular pressure and decrease corneal thickness if used over a 24 months.
