Switching efficacy on intraocular pressure from latanoprost to bimatoprost in eyes with open angle glaucoma: implication to the changes of central corneal thickness
Sawada A; Yamamoto TJapanese Journal of Ophthalmology 2014; 58: 423-428
PURPOSE: Intraocular pressure (IOP)-lowering effects of 0.03 % bimatoprost in eyes with open angle glaucoma (OAG) was compared with that of 0.005 % latanoprost. METHODS: Thirty-one patients with OAG who had received three kinds of ocular hypotensive agents (latanoprost, beta-blocker, and topical carbonic anhydrase inhibitor) were included in this study. In these patients, bimatoprost was administered for 8 weeks after switching from latanoprost. The IOP was measured with a goldmann applanation tonometer (GAT) at the baseline, and Weeks 2, 4 and 8 after switching the treatment. The IOP at the baseline and at the end of treatment period was measured at 10:00, 12:00, and 16:00. The central corneal thickness (CCT) was measured at each visit using an ultrasonic pachymeter. RESULTS: At the baseline, the mean IOP was 18.8 ± 1.4 mmHg, and the CCT was 530.7 ± 29.5 μm. At Week 8 after switching treatment, bimatoprost significantly reduced the IOP by 2.0 ± 1.6 mmHg from the baseline (p < 0.001). The CCT tended to be reduced (p = 0.009; Repeated ANOVA) and Bonferroni test indicated a statistically significant decrease of the CCT at Week 8 in comparison with that at the baseline (p = 0.013). CONCLUSIONS: Bimatoprost has an IOP-lowering effect superior to that of latanoprost in glaucoma patients after switching from latanoprost. The use of bimatoprost can decrease the CCT for a relatively short period in a linear regression fashion.
