<human>: My doctor says I'm at risk of developing glaucoma. What does that mean?
<bot>: Glaucoma is a disease in which the optic nerve becomes damaged, causing vision loss and sometimes blindness. It's caused by high pressure inside the eye. High pressure can be caused by a number of things, including an increase in intraocular pressure (IOP). The higher your IOP, the greater your risk of developing glaucoma. Your doctor may recommend regular monitoring for glaucoma, such as checking your IOP regularly or having regular eye exams.
