Objectives: To evaluate the effectiveness of latanoprost and dorsolamide-timolol fixed combination therapy as initial treatment for treatment naïve patients with intraocular pressure (IOP) values over 30 mm Hg.
Methods: Twenty-five eyes of 25 newly diagnosed patients whose IOP measurements were at least 30 mmHg and who did not receive any antiglaucomatous medication previously were included in the study. Sixteen eyes had primary open angle glaucoma and 9 eyes had pseudoexfoliation glaucoma. Visual acuity, iridocorneal angle, intraocular pressure, optic nerve head and computerized visual field test were evaluated in each patient. Patients were evaluated on the first and third months of therapy for IOP reduction and ocular side effects.
Results: The baseline average IOP was 38.4 ± 7.0 mmHg initially, at first month average IOP was 16.3± 3.7mmHg and at third month average IOP was 18.6 ± 4.2 mmHg. IOP reduction from baseline was 22.1 ± 9.0 mmHg (55.7± 14.5 %) for the first month, 19.8 ± 8.9 mmHg (49.6 ± 15.9 %) for the third month (p=0.0001) None of the patients reported any serious side-effects about therapy. Five (20%) had moderate hyperemia, 2 (8%) reported metallic taste.
Conclusion: The combined therapy of latanoprost and dorsolamide/timolol fixed combination as initial treatment for intraocular pressure over 30 mmHg is highly efficient and well tolerated for treatment naive glaucoma.
