Meaning
青光眼 is the medical term for glaucoma, a serious eye disease characterized by increased intraocular pressure that can damage the optic nerve and lead to vision loss or blindness. The name literally means 'green light eye,' referring to the greenish or bluish appearance the pupil can take on in certain types of acute glaucoma.
Usage
This is a formal medical term used by doctors, patients, and in healthcare contexts. It's commonly seen in medical literature, hospital signage, and health insurance documents. Laypeople discussing eye health will use this exact term rather than informal alternatives.
