Closed-Angle Glaucoma
Definition:
Closed-angle glaucoma is a type of eye condition where the iris (the colored part of your eye) blocks the drainage of a fluid called aqueous humor. This can lead to a sudden increase in pressure inside the eye, which can cause serious damage to your vision if not treated quickly.

Example Sentence:
"The doctor diagnosed her with closed-angle glaucoma after she complained of severe eye pain and blurred vision."
Advanced Usage:

Word Variants:
