Abstract
Purpose: To compare the efficacies of latanoprost 0.005%, travoprost 0.004%, and tafluprost 0.0015% in reducing diurnal intraocular pressure (IOP) fluctuations in patients with newly diagnosed primary open-angle glaucoma (POAG). Methods: In this prospective randomized clinical trial, 60 patients who were newly diagnosed with POAG were divided into three equal groups. Patients were examined at presentation and at second and sixth weeks. Diurnal phasing of IOP was conducted using a calibrated Goldmann applanation tonometer. IOP measurements were recorded from 8:00 am to 9:00 am, from 3:00 pm to 4:00 pm, and from 7:00 pm to 8:00 pm. Results: The study groups were distributed similarly in terms of age and gender ( p-values: 0.76) and the participants had a mean age of 52.98 ± 13.43 years. The IOP at the day of inclusion was not statistically significant among the three groups ( p-values 0.27, 0.51, and 0.64 at 8 am, 2 pm, and 8 pm, respectively). Similar nonsignificant differences were noticed on the follow-up visits. However, the tafluprost group showed a significant reduction in IOP on the follow-up visit at the second week at 8 pm (30.5% reduction, p-value: 0.03). All three drugs showed a comparable and significant reduction in IOP and IOP fluctuations. The pattern of side effects was similar in all the groups. Conclusion: Latanoprost, travoprost, and tafluprost show a similar effectiveness in reducing the mean IOP and the diurnal IOP fluctuation in POAG. Importantly, the three drugs have comparable tolerability with insignificant differences regarding the pattern of their side effects.
