For Fuchs endothelial dystrophy, what is the intended effect of the prescribed eye drop?

• A. Keep the cornea dehydrated
• B. Increase tear production
• C. Reduce pupil size
• D. Lower intraocular pressure

Answer: (A)

Fuchs endothelial dystrophy causes corneal swelling because the endothelial cells can’t pump fluid out of the stroma effectively. The prescribed eye drop is intended to pull water out of the cornea by osmosis, reducing edema and improving clarity. This keeps the cornea dehydrated, which is the key therapeutic aim. Other strategies like increasing tear production, constricting the pupil, or lowering intraocular pressure don’t address the underlying corneal edema in this condition.
