Sample itemAn older adult develops painless glare and progressive blurred vision because which structure has become opaque?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
B. Crystalline lens
Cataract is opacity of the crystalline lens, which scatters light and causes painless progressive blur, glare, and reduced contrast sensitivity.
Option by option
A. Corneal endothelium
Corneal endothelium dysfunction causes edema, not typical age-related cataract.
B. Crystalline lens (correct)
Correct: lens opacity produces the symptoms of cataract.
C. Optic nerve
Optic nerve disease causes different visual loss patterns.
D. Macula
Macular disease causes central distortion rather than lens glare.
