Q. Which of the following is an early symptom of glaucoma?

A. Hazy vision.
B. Loss of central vision.
C. Blurred or "sooty" vision.
D. Impaired peripheral vision.

Correct Answer: D


Explanation: In glaucoma, peripheral vision is impaired long before central vision is impaired. Hazy, blurred, or distorted vision is consistent with a diagnosis of cataracts. Loss of central vision is consistent with senile macular degeneration but it occurs late in glaucoma. Blurred or "sooty" vision is consistent with a diagnosis of detached retina.
