What is the function of miotics in glaucoma management?

Miotics function in glaucoma management primarily by decreasing the size of the pupil, which in turn improves the outflow of aqueous humor, the fluid within the eye. This reduction in pupil size facilitates the opening of the trabecular meshwork, enhancing the drainage of intraocular fluid. Improved drainage helps to lower intraocular pressure, which is critical in managing glaucoma and preventing damage to the optic nerve.

The action of miotics is particularly beneficial for patients with open-angle glaucoma, as they can effectively reduce elevated eye pressure and mitigate the risk of optic nerve damage. The increase in drainage due to the constriction of the pupil is a pharmacological approach aimed specifically at managing the challenges posed by glaucoma.
