Miotic drugs: a review of ocular, visual, and systemic complications.

Cholinergic drugs and anticholinesterases have caused ocular complications including cataracts, iris cysts, retinal detachment, iritis, increased intraocular tension, allergic and toxic reactions, and hypermia. The visual complications include accommodative spasm; myopia and reduced visual acuity; changes in vision sensitivity, dark adaptation, and visual fields; and discomfort. The systemic complications are those common to cholinergic drugs and anticholinesterases. This review is intended as a ready reference to the drugs that cause such effects and source material.
