Question Of The Day: Neurosensory Disorders

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.
