Question 1 of 5
Anticholinergic drugs are used in Ophthalmology because they produce what effect?
Correct Answer: C
Rationale: The correct answer is C: Pupil dilation. Anticholinergic drugs block the action of acetylcholine, leading to pupil dilation by inhibiting the constriction of the sphincter muscle in the iris. This effect is beneficial in ophthalmology for procedures like dilation exams and treating conditions like uveitis.
Choice A is incorrect as anticholinergics cause pupil dilation, not restriction.
Choice B is incorrect because anticholinergics actually increase lacrimal secretions instead of decreasing them.
Choice D is incorrect as sedation is not a typical effect of anticholinergic drugs in ophthalmology.
