Glaucoma is a general term used to describe a group of eye disorders that damage the optic nerve. It’s the most common form of optic nerve damage leading to vision loss. In most cases, fluid builds up in the front part of the eye. This extra fluid puts pressure on the eye, gradually damaging the optic nerve. This pressure is known as intraocular pressure (IOP), or eye pressure.
Glaucoma is one of the leading causes of blindness for people over the age of 60. It can occur at any age but is more common in older adults.
Symptoms of angle-closure glaucoma usually come on faster and are more obvious. Damage can happen quickly. If you have any of these symptoms, get medical care right away:
- Severe headache.
- Eye pain.
- Nausea and vomiting.
- Blurred vision.
- Halos around lights.
- Eye redness.
