Miotic

A miotic ( plural : miotics ) is a medicine to constrict the pupil ( miosis ). It is used for diagnostic or therapeutic purposes in human and veterinary ophthalmology and belongs to the group of drugs called parasympathomimetics . The pupil constriction is caused by irritation of the sphincter pupillae muscle . With regard to their mode of action, a distinction is made between directly and indirectly acting miotics.

Miotics are mainly used therapeutically in the treatment of glaucoma , although they are usually contraindicated in secondary glaucoma . Diagnostic areas of application are, for example, pharmacodynamic pupil examinations.

Known side effects can include: variable myopia , accommodation spasms , inadequate light adaptability or local pain sensation.

Common miotics include: pilocarpine , acetylcholine , prostigmine , histamine and morphine . These are usually prescription drugs.
