[The alpha-adrenergic effect of thymoxamine on the vessels of the ciliary body].
The effects of epinephrine on the permeability of the blood-aqueous barrier, stimulated by paracentesis of the anterior chamber, were studied in rabbits following alpha-adrenergic blocking by means of topical or systemic thymoxamine. The alpha-adrenergic block was tested by continuous recording of the systemic arterial blood pressure. The reversal of the vascular effects of epinephrine after administration of thymoxamine was demonstrated at the bloodaqueous barrier. The miotic property of thymoxamine is believed to have had no influence on our results.
