Definition

Noun: A medicated liquid solution administered as drops into the eye to treat glaucoma. Its primary therapeutic action is to constrict (make smaller) the pupil, which in turn increases the drainage of aqueous humor (the fluid inside the eye), thereby reducing intraocular pressure.

Usage

This term is used specifically in medical and pharmaceutical contexts to refer to this type of glaucoma medication. It is a countable noun. * The ophthalmologist prescribed a miotic eyedrop to manage the patient's intraocular pressure. * Pilocarpine is a common type of miotic eyedrop.

Advanced Usage

• The term is often used in contrast to other classes of glaucoma medications, such as beta-blocker eyedrops or prostaglandin analogs, which work through different mechanisms.
• It can be part of a combination therapy regimen for glaucoma.

Noun

1. a treatment for glaucoma; the eyedrops increase the outflow of aqueous humor by constricting the pupil
