Carbachol is primarily used for which condition?

Explanation:
Carbachol lowers intraocular pressure by acting directly on muscarinic receptors in the eye. This stimulation causes the ciliary muscle to contract, which opens the trabecular meshwork and Schlemm’s canal, increasing aqueous humor outflow. The net effect is a drop in intraocular pressure, which helps treat glaucoma. It isn’t used for hypertension, Parkinson’s disease, or migraine because those conditions don’t benefit from cholinergic-induced drainage of eye fluid and would be worsened by systemic cholinergic effects.
