Glaucoma is a common eye problem that causes vision loss due to damage to the optic nerve. If untreated, glaucoma can cause blindness.
There are 2 main types of glaucoma: open-angle and closed-angle glaucoma, and can also be described as primary or secondary, as well as chronic or acute.
Acute angle-closure glaucoma involves sudden, severe eye pain with nausea and vomiting, headache and blurred vision. This is an emergency and you should seek prompt treatment so you don’t lose vision.
