    Abstract:
    PURPOSE: To compare the effects of latanoprost, travoprost, and bimatoprost on central corneal thickness (CCT). METHODS: A total of 69 eyes of 69 patients with glaucoma or ocular hypertension submitted to monotherapy with prostaglandin analogues (latanoprost 0.005%, travoprost 0.004%, or bimatoprost 0.03%) during a mean of 17.19 ± 15.71 months follow-up period. Measurements were performed at the initial diagnosis and at the end of follow-up. All the measurements were carried out by the same doctor between 9 am and 11 am, using Goldmann applanation tonometer for intraocular pressure and ultrasonic pachymetry for CCT. RESULTS: A statistically significant reduction in CCT was observed in all groups (P < 0.001). The reduction of CCT in the latanoprost, travoprost, and bimatoprost groups was 14.95 ± 5.04, 15.73 ± 3.25, and 17.00 ± 6.23 μm, respectively. No significant difference was found in the reduction of CCT among the 3 groups (P > 0.05). No significant difference was also found in the reduction of CCT between the patients with less than or equal to 6 months' treatment and the patients with more than 6 months' treatment in the 3 groups (P > 0.05). CONCLUSIONS: Topical therapy with prostaglandin analogues is associated with CCT reduction. Latanoprost, travoprost, and bimatoprost have a similar effect on CCT.
