Full Answer

The main symptoms of open-angle glaucoma are gradual loss of peripheral vision and tunnel vision in both eyes. The symptoms of acute angle-closure glaucoma may be eye pain, nausea and vomiting that accompany eye pain, blurred vision and reddening around the eyes, explains the Mayo Clinic. Some patients have reported seeing halos around lights. Often, primary open-angle glaucoma presents few symptoms before causing permanent damage.

Both forms of glaucoma are categorized as primary and secondary diseases, notes the Mayo Clinic. Glaucoma is a primary condition when the cause is unknown. Glaucoma is considered secondary when it can be linked to a cause such as eye injury, inflammation, tumor, cataract or diabetes. Individuals who are experiencing vision issues should contact a doctor immediately.

Since glaucoma can impair vision well before symptoms become apparent, it is important to understand who is at risk for glaucoma, according to the Mayo Clinic. Individuals with a history of high internal eye pressure are at an increased risk of developing glaucoma. Age, ethnicity, family history of glaucoma and long-term use of corticosteroids increase one's risk of developing the condition.
