Anticholinergic drugs are used in Ophthalmology because they produce what effect?

Pupil restriction.

Decreased lacrimal secretions.

Pupil dilation.

Sedation.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Anticholinergic drugs do not cause pupil restriction; they relax the muscles around the eye, leading to dilation.

Choice B rationale

Decreased lacrimal secretions are a secondary effect of anticholinergics and not their primary purpose in ophthalmology.

Choice C rationale

Anticholinergics cause pupil dilation (mydriasis) by relaxing the muscles that constrict the pupil, allowing for a better examination of the eye's interior.

Choice D rationale

Sedation is not a primary effect of anticholinergics used in ophthalmology.
