[The effect of levobunolol eyedrops on trabecular outflow of aqueous humor in chronic simple glaucoma].
The present paper reports a double-blind, cross-over, randomized study in which 31 patients (62 eyes) suffering from open-angle glaucoma were included. These patients were treated for one year with 0.5% levobunolol and 0.5% timolol ophthalmic solutions and followed up. Tonographic examinations of outflow facility showed a statistically significant increase following topical applications of 0.5% levobunolol, while there was little change with 0.5% timolol. The difference in the effect of outflow facility due to instillations of 0.5% levobunolol and 0.5% timolol can be explained by the different pharmacokinetic profiles of the two beta-blocker solutions in topical ocular application.
