Eye drops of RU 486-6, a peripheral steroid blocker, lower intraocular pressure in rabbits.

A peripheral corticosteroid blocker RU 486-6, instilled as a 1% suspension at random into one eye of 12 rabbits, produced a consistent fall in intraocular pressure as measured by a hand-held applanation tonometer, when compared with the fellow control eye. This or a similar drug may be applicable for treatment of human open-angle glaucoma, or ocular hypertension, by eliminating that part of ocular tension attributable to the effect on aqueous outflow of the normal and fluctuating level of tissue corticosteroids.
