How does Wet AMD affect vision?

• A. Peripheral field loss is common
• B. Sudden complete blindness can occur
• C. It impairs central vision, causing straight lines to appear wavy
• D. Color vision is typically affected first

Answer: (C)

Wet AMD hits the central retina, the macula, where fine detail and straight-line vision live. New abnormal blood vessels leak fluid and blood under the macula, causing swelling and damage. This central disturbance leads to metamorphopsia—straight lines looking bent or wavy—and a loss of detailed central vision. Peripheral vision is usually preserved because the outer, peripheral retina isn’t the part most affected. That’s why the statement describing central vision impairment with straight lines appearing wavy matches what Wet AMD causes. The other ideas don’t fit as well: peripheral field loss isn’t the hallmark, sudden complete blindness is not typical, and color vision isn’t usually the first or primary change in Wet AMD.
