What is the effect of pilocarpine in ophthalmic care?

Pilocarpine is a medication commonly used in ophthalmic care, primarily as a miotic agent. Its main effect is to induce miosis, or constriction of the pupil. This is achieved by stimulating the parasympathetic nervous system, which causes the constrictor muscle of the iris to contract. The resulting smaller pupil increases the outflow of aqueous humor from the anterior chamber, which can be beneficial in treating conditions like glaucoma.

The action of pilocarpine can also help facilitate better contact lens fitting and improve visibility of the retina during exams by allowing more light to enter the eye when the pupil is constricted. Understanding the pharmacological effects of pilocarpine is crucial for ophthalmic surgical assistants, as it can influence treatment plans and patient care strategies.

In contrast, alternatives listed do not align with pilocarpine's pharmacological actions. For instance, it does not increase intraocular pressure; rather, it helps lower pressure in glaucoma patients. It also does not decrease tear production, nor is it primarily known for enhancing corneal healing. Understanding these distinctions is essential for applying proper ophthalmic practices and ensuring effective patient treatment.
