Pharmaceutical compositions and a method are disclosed for treating glaucoma and/or ocular hypertension in the mammalian eye by administering to the mammalian eye the pharmaceutical composition of the invention which contains, as the active ingredient, one or more compounds having potassium channel blocking activity. Examples of potassium channel blockers utilized in the pharmaceutical composition and method of treatment are quinine, tremogenic indole alkaloids, such as Penitrem A and paspalicine, and insect toxins such as charybdotoxin and iberiotoxin.

Pharmaceutical compositions and a method are disclosed for treating glaucoma and/or ocular hypertension in the mammalian eye by administering to the mammalian eye the pharmaceutical composition of the invention which contains as the active ingredient one or more compounds having calcium chelating activity. Examples of calcium chelating agents utilized in the pharmaceutical composition and method of treatment are: ##STR1## and lower alkyl and alkoxyalkyl esters thereof.

Pharmaceutical compositions and a method are disclosed for providing neuroprotective effect to the mammalian eye by administering to the mammalian eye the pharmaceutical composition of the invention which contains, as the active ingredient, one or more compounds having chloride channel blocking activity. Examples of chloride channel blockers utilized in the pharmaceutical composition and method of treatment are: ##STR1## wherein R is hydrogen or a pharmaceutically-acceptable cation, e.g. an alkali or alkaline earth metal, or a quaternary amine; or R represents a ester-forming moiety, e.g. a lower alkyl radical, having up to six carbon 20 atoms, that may be derived from a lower alkanol.

A method for inducing prolonged pseudoaccommodation includes the instillation of an ophthalmic formulation into an eye for contracting the iris sphincter muscle, but not the ciliary muscle, in order to cause sphincter muscle contraction for a period of greater than about one hour per installation. The method further provides for the stabilization of an implanted intraocular lens immediately after surgery and for reducing glare following radial keratotomy.
