For blurred vision due to anticholinergic effects, which treatment is recommended?

• A. Artificial tears
• B. Saline eye drops
• C. Pilocarpine 0.5% eye drops
• D. Eyedrops containing tropicamide

Answer: (C)

Blurred near vision from anticholinergic effects happens because blocking muscarinic receptors in the eye prevents the pupil from constricting and the ciliary muscle from contracting, leaving the lens out of proper focus for close tasks. To reverse this, you want a drug that stimulates muscarinic receptors in the eye. Pilocarpine is a direct muscarinic agonist; when used as eye drops, it activates the iris sphincter and the ciliary muscle, causing miosis and accommodation, which restores focusing for near vision and reduces blur. The 0.5% formulation is a common, effective option. Artificial tears or saline drops mainly address surface moisture and don’t fix accommodative loss, while tropicamide is an antimuscarinic that dilates the pupil and paralyzes accommodation, making blur worse. Hence, pilocarpine is the best choice.
