1.Types of Glaucoma: Open-Angle
There are 4 main kinds of glaucoma. The most common is open-angle glaucoma, which affects about 90% of people with the disease. It’s called «open angle» because there’s a clear opening to the drainage canal, which gets clogged further inside. This type comes on slowly. You may not notice any symptoms at first.
2.Types of Glaucoma: Angle-Closure
This type comes on fast and it’s a medical emergency. It typically happens to people with a narrow opening to their drainage canal, which gets blocked suddenly. That keeps fluid from flowing out of your eye. Pressure inside the eye rises quickly. If you get severe eye pain, headache, nausea, or vision loss, get medical help right away to prevent blindness. You’ll likely need surgery to open up the drainage canal.
