## Definition

a medical condition where pressure builds up inside your eye. If it is not treated, it can damage your vision and even cause blindness.

For teachers: a group of eye conditions characterised by damage to the optic nerve, typically caused by abnormally high intraocular pressure. Left untreated, it leads to progressive, irreversible vision loss.

## Examples

- Regular eye exams can help detect glaucoma early.
- The doctor prescribed daily eye drops to manage the patient's glaucoma and prevent further nerve damage.
- Because glaucoma often presents without early symptoms, it is frequently referred to as the silent thief of sight, making routine screenings essential for those with a family history of the condition.

## Usage notes

- Usually uncountable when referring to the disease; can be countable when referring to specific clinical types.
