title: Acute effect of thymoxamine on aqueous humor formation in the epinephrine-treated normal eye as measured by fluorophotometry.
abstract: The acute effect of 0.5% thymoxamine and 1% epinephrine on aqueous humor flow was evaluated by fluorophotometry in 25 normal human subjects in a randomized, double-blind, placebo-controlled study. Changes in intraocular pressure, anterior chamber volume, and pupil diameter were also measured. The results of this study indicate that epinephrine alone increases aqueous humor flow by 19% and that thymoxamine in a dose sufficient to produce miosis does not alter this acute effect of epinephrine.
