Definition

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

n. 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.”
