[Effect of adrenaline on the secretory activity of the ocular ciliary body in rabbits]

In intact rabbits and in rabbits with intracerebral unilateral section of the n. oculomotorius, instillation of 2 drops of 0.1% adrenaline into the conjunctival sack increased and then decreased the intraocular pressure (IOP); i.v. administration of adrenaline (50 mcg) or electrophoresis decreased IOP. In conditions of disturbed parasympathetic innervation of the eye its sensitivity to adrenaline increased as revealed by a sharper lowering of IOP.
