In order to study the influence of clonidine on intraocular pressure (IOP), the drug was administered via different routes. The experiments were performed on chloraloseanaesthetized cats. The rise in lOP observed after administration of clonidine into the external carotid arteries was subjected to a

✦ Synopsis
A9-Tetrahydrocannabinol (•9-THC) was injected both intravenously and into the brain stem via the left vertebral artery. Contrary to results obtained with clonidine, neither the fall in intraocular pressure (IOP), nor the arterial hypotension induced by A9-THC, were enhanced after the 'central' administration of the drug. For clonidine, a central mechanism underlying the ocular hypotensive effect has recently been proposed. This suggestion is based upon the enhanced fall in IOP after 'central' administration of clonidine. The pontomedullary area is considered to be the main initial target of this drug. Obviously, the IOP-lavering mechanism of A9-THC is different from that of clonidine.
