The Effect of Vasopressin on Choroidal Blood Flow, Intraocular Pressure, and Orbital Venous Pressure in Rabbits

Abstract

AVP reduces IOP and OVP significantly and is a potent vasoconstrictor in the choroidal vascular bed. In the choroid, the effect of AVP is not only dose-dependent, but also PP-dependent, which is indicated by the reduced perfusion relative to control with low-dosed AVP at low PP.
