Miotics, or parasympathomimetic agents, are primarily used in the treatment of glaucoma. They function by inducing miosis, which is the constriction of the pupil. This constriction results in an increase in the trabecular meshwork's outflow of aqueous humor, thereby lowering intraocular pressure—an important factor in managing glaucoma.

Glaucoma is characterized by elevated intraocular pressure, which can lead to damage to the optic nerve and vision loss if left untreated. By administering miotics, the physician helps facilitate the flow of fluid out of the eye, effectively reducing this pressure.

In contrast, conditions such as cataracts, macular degeneration, and retinal detachment are not primarily treated with miotics. Cataracts involve lens opacification and require surgical intervention. Macular degeneration is a condition affecting the retina and typically involves other treatments, including laser therapy and anti-VEGF injections. Retinal detachment requires surgical repair to reattach the retina. Miotics do not address the underlying issues in these disorders, making their use specific to glaucoma management.
