acute glaucoma

A patient experiences sudden eye pain from acute glaucoma.

Definition

Noun: - A serious eye condition: Acute glaucoma is a specific type of glaucoma, a group of eye diseases. It is characterized by a sudden, severe increase in pressure inside the eye. This happens because the drainage angle where fluid normally exits the eye becomes completely blocked, often by the iris. The rapid pressure buildup can cause permanent damage to the optic nerve and vision loss within a short period if not treated immediately.

Usage Examples
  • Noun:
    • The patient was rushed to the emergency room with symptoms of acute glaucoma.
    • Acute glaucoma is a medical emergency requiring prompt treatment to prevent blindness.
    • Unlike the more common open-angle glaucoma, acute glaucoma causes sudden pain and blurred vision.
Advanced Usage
  • "An attack of acute glaucoma": This phrase describes the sudden onset of the condition.
    • She suffered an attack of acute glaucoma, experiencing severe eye pain and nausea.
Variants and Related Words
  • Closed-angle glaucoma (n): Another medical term for acute glaucoma, referring to the blocked drainage angle.
    • Closed-angle glaucoma and acute glaucoma are often used synonymously.
  • Angle-closure glaucoma (n): A synonymous term emphasizing the closure of the eye's drainage angle.
  • Primary angle-closure glaucoma (PACG) (n): The formal clinical classification for this condition.
Synonyms
  • Closed-angle glaucoma: A direct synonym.
  • Angle-closure glaucoma: A direct synonym.
  • Narrow-angle glaucoma: A term sometimes used, though it can refer to a pre-acute stage where the angle is narrow but not fully closed.
Related Phrases
  • Intraocular pressure (IOP): The fluid pressure inside the eye, which becomes dangerously high in acute glaucoma.
  • Optic nerve damage: The permanent injury to the nerve connecting the eye to the brain, which acute glaucoma can cause.
