The Comparative Cardiovascular, Pulmonary, Ocular Blood Flow, and Ocular Hypotensive Effects of Topical Travoprost, Bimatoprost, Brimonidine, and Betaxolol

Abstract

Travoprost and bimatoprost were found to be systemically safe and caused an increase in blood-flow velocities of the retrobulbar vessels after a single-dose application. Their ocular hypotensive effect was comparable to that of brimonidine and greater than that of betaxolol in healthy subjects.
