Anticholinergic drugs are used in Ophthalmology because they produce what effect?
Pupil restriction.
Decreased lacrimal secretions.
Pupil dilation.
Sedation.
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.
