Abstract

Purpose: To compare the clinical success rates and quality of life impact of brimonidine 0.2% with timolol 0.5% in newly diagnosed patients naive to glaucoma therapy. Methods: A prospective, multicenter, randomized, double-masked, clinical effectiveness trial in which the clinical outcomes of twice daily brimonidine tartrate 0.2% were compared with those of timolol maleate 0.5% in patients with glaucoma and ocular hypertension was conducted. Two hundred nineteen patients were enrolled - 111 in the brimonidine group and 108 in the timolol group. Patients instilled their study medications twice daily for 4 months. Factors for determining clinical success were reduction of intraocular pressure (IOP), safety, and adverse events. Quality of life effects were assessed with the SF-36 Health Survey and Glaucoma Disability Index questionnaires. Results: Clinical success was 71% (75/106) with brimonidine and 70% (73/105) with timolol as initial treatment. The overall mean decrease in lOP was 6.5 mm Hg with brimonidine and 6.2 mm Hg with timolol. Few patients reported a specific adverse event and, with the exception of a slightly higher rate of ocular burning and stinging in the brimonidine group, there were no significant between-group differences. No significant chronotropic effects on the heart were seen with brimonidine, while small but significant mean decreases in heart rate were seen at months 1 and 4 with timolol. Mean systolic and diastolic blood pressure remained relatively stable in both groups. Quality of life remained stable, with no significant between-group differences. Conclusions: As a first-line agent for the treatment of glaucoma and ocular hypertension, brimonidine has clinical effectiveness equivalent to timolol, but with less chronotropic effect on the heart. Brimonidine is a viable alternative to timolol for first-line therapy in glaucoma and ocular hypertension.
