At least theoretically it has a greater physiologic activity than other forms of epinephrine, since it should penetrate the cornea more easily than the solutions of low pH now available. Also, the lack of irritation means less dilution of the drug by tears. A preliminary clinical trial on a small number of patients with open-angle glaucoma has yielded encouraging results.

Although there were several earlier reports of the use of epinephrine in the treatment of
