Question: 1 / 400

What is the name of the drugs that are used to dilate the pupils?

Myotics

Mydriatics

Mydriatics are the class of drugs specifically designed to dilate the pupils. When administered, these medications work by relaxing the muscles of the iris, which is responsible for controlling the size of the pupil. This dilation is essential during eye examinations as it allows healthcare professionals to get a better view of the internal structures of the eye, including the retina and optic nerve.

In contrast, myotics are used to constrict the pupils, which is the opposite effect of what mydriatics achieve. Beta-blockers are primarily used to manage intraocular pressure in conditions such as glaucoma, while topical anesthetics are used to numb the surface of the eye for various procedures. Thus, the primary function of mydriatics aligns directly with the purpose of pupil dilation, making them the correct choice for this question.
