Purpose: To determine the intraocular pressure–lowering efficacy and adverse effects of travoprost and bimatoprost. Methods: Patients who were newly diagnosed as POAG at the outpatient department of our clinic between April 2002 and March 2005 and received topical anti-glaucoma medical therapy, were enrolled in this retrospective study. The cases were divided into two treatment groups for administration of travoprost(Group 1) and bimatoprost(Group 2). Eightythree eyes of 45 patients were followed up for 8.92(SD: 4.347) months in group 1 and 9.72(SD: 4.91) months in ngroup 2. Intraocular pressure changes, cup-to-disc ratios, visual field findings, central corneal pachymetry, ocular and systemic adverse effects, need for combination therapy and need for surgical therapy were followed and all of the findings were compared. Results: The mean pre-treatment IOP of group 1 was 25.29 mmHg while the mean post-treatment IOP was 17.80 mmHg and the mean decrease in IOP of 7.49 mmHg(29.61% ). In group 1, the most common ocular side effects were foreign body sensation in 4 patients(19.51%), ocular hyperemia in 2 patients (%9.75) and eyelash lengthening in 2 patients (%9.75). We switched the medical therapy in 2 patients (%9.75), started combined medical therapy in 6 patients(%24.39) and performed trabeculectomy in 3 patients(%12.19). In bimatoprost group(group 2) the mean pre-treatment IOP was 23.64 mmHg while the mean post-treatment IOP was 17.64 mmHg and the mean decrease in IOP was 6.00 mmHg (%25.38). In group 2 the most common ocular side effects were foreign body sensation in 6 patients (%28.57), ocular hyperemia in 5 patients (%23.80) and eyelash lengthening in 1 patient (%4.76). We switched the medical therapy in 2 patients (%9.52) and started combined medical therapy in 3 patients (%14.28). There was no statistical difference between two groups in IOP lowering effect (p=0.556). Conclusion: Both travoprost and bimatoprost are effective choice choices in reducing IOP in patients with POAG.
