Which statement best describes closed-angle glaucoma?

• A. It is a chronic, nonurgent condition.
• B. It is not related to the eye's drainage angle.
• C. It is an emergency requiring urgent care.
• D. It is a medical emergency.

Answer: (D)

Closed-angle glaucoma is a sudden, dangerous rise in eye pressure caused by a rapid closure of the eye’s drainage angle. That abrupt pressure increase can quickly damage the optic nerve and permanently affect vision if not treated right away. Because of how quickly things can deteriorate and the high risk to sight, it is classified as a medical emergency requiring immediate evaluation and treatment. Treatments aim to rapidly lower intraocular pressure and prevent irreversible damage, often followed by definitive procedures to prevent recurrence. The other statements miss this urgency or the mechanism: it’s not a chronic, nonurgent condition, and it is directly related to the drainage angle. While it does require urgent care, the emphasis on it being a medical emergency best captures the seriousness and time sensitivity involved.
