What Are the Symptoms of Glaucoma?


Quick Answer

There are two types of glaucoma, primary open-angle glaucoma and angle-closure glaucoma, and the symptoms vary between the two types, states Mayo Clinic. Symptoms for primary open-angle glaucoma are the gradual loss of peripheral vision and tunnel vision, while the symptoms for angle-closure glaucoma are eye pain, nausea and vomiting, blurred vision, halos around lights and reddening of the eye.

Both open-angle glaucoma and angle-close glaucoma can present as primary or secondary conditions, according to Mayo Clinic. A primary condition occurs when the cause is not known, while a secondary condition can be traced to a known cause, such as eye injury, medications, inflammation, a tumor, advanced cataract or diabetes.

If an individual notices an eye problem, he should seek the advice of a doctor. Primary open-angle glaucoma does not give many warning signs before permanent damage occurs, so it is important to detect it as early as possible. The best way to detect glaucoma early is with regular eye exams. The American Academy of Ophthalmology recommends a comprehensive eye exam for all adults over the age of 40, explains Mayo Clinic. If there are no risk factors, the exam should be done every three to five years after the initial screening. Those who have risk factors or are over the age of 60 should be screened for glaucoma every one to two years.

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.
