Glaucoma
What are the signs and symptoms of the condition?
Because the vision loss is gradual, there may be no symptoms during the early stages. The person may not be aware of blind spots developing, and there is no pain or redness. In one type of glaucoma, called acute angle-closure glaucoma, there is a sudden rise in pressure, and the following symptoms may occur:
blurred vision
severe eye pain
headache
nausea and vomiting
perception of rainbow rings or halos around lights at night
Most cases of glaucoma are the chronic open-angle type. In this type, there is a gradual blockage of fluid outflow over the years. This type of glaucoma is usually found during an eye exam.
