What is the primary effect of Pilocarbine in the treatment of glaucoma?

• A. Increase aqueous humor production
• B. Increase aqueous outflow
• C. Decrease aqueous outflow
• D. Suppress aqueous inflow

Answer: (C)

The primary effect of Pilocarpine in the treatment of glaucoma is to increase aqueous outflow. This medication is a muscarinic agonist, which acts on the ciliary muscle and the trabecular meshwork in the eye. By stimulating the ciliary muscle, Pilocarpine promotes contraction, which leads to widening of the trabecular meshwork and facilitates the drainage of aqueous humor from the anterior chamber of the eye. This outflow reduction is crucial in managing intraocular pressure, which is often elevated in glaucoma. Higher intraocular pressure can lead to damage to the optic nerve and subsequent vision loss, so medications that enhance aqueous humor outflow, like Pilocarpine, are a standard treatment strategy. The other options listed don't align with the pharmacological actions of Pilocarpine. For instance, options that suggest increasing production or suppressing inflow do not accurately represent how Pilocarpine functions. Therefore, the focus on aqueous outflow is essential for understanding how Pilocarpine addresses the elevated intraocular pressure typical in glaucoma patients.
