Which of the following is not typically associated with acute angle-closure glaucoma?

• A. Headache
• B. Severe eye pain
• C. Clear vision with no pain
• D. Halos around lights

Answer: (C)

Acute angle-closure glaucoma presents as a sudden, emergency rise in intraocular pressure that causes rapid, severe eye pain, often accompanied by a headache, red eye, and blurred vision. Halos around lights appear because corneal edema and high pressure scatter light. The eye typically feels hard to the touch, and patients may have nausea or vomiting. Because of the abrupt pressure increase and inflammatory response, pain and visual disturbance are central features.

The option describing clear vision with no pain does not fit this picture. During an acute attack, vision is usually blurred or decreased and pain is present, not a painless, clear-vision scenario.
