In a double-masked, randomized, controlled clinical trial, the authors evaluated the ocular hypotensive efficacy of twice-daily treatment with levobunolol (0.25 and 0.5%) and betaxolol (0.5%) in 85 patients with open-angle glaucoma or ocular hypertension. During the 3-month study, intraocular pressure (IOP) reductions in the two levobunolol groups were significantly greater than in the betaxolol group. From a mean baseline IOP of approximately 25 mmHg, overall mean reductions were 6.2 and 6.0 mmHg for the 0.25 and 0.5% levobunolol groups, respectively, and 3.7 mmHg for the betaxolol group. No clinically or statistically significant among-group differences were noted in the systemic safety variables evaluated. These data suggest that although all three treatments are effective, levobunolol provides a greater reduction in IOP than betaxolol.

D005901 Glaucoma An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches.
