Miotics increase drainage of intraocular fluid by making the pupil size smaller, thereby increasing the flow of intraocular fluid from the eye.

What are miotics used for?

Miotics (drugs that cause the pupil to contract) improve the outflow of aqueous as part of the treatment of glaucoma and reduce the risk of a posteriorly luxated lens entering the anterior chamber.

What are miotics used for in glaucoma?

Miotics are eye drops that cause the pupil to constrict, allowing the blocked drainage angle to open. They may be used two, three, or four times daily. These medications are now reserved for use in people whose glaucoma does not improve with other medications. Miotics may cause some eye discomfort and redness.
