Over 4.2 million individuals in the U.S. are affected by glaucoma, a prominent contributor to vision impairment nationwide. While glaucoma currently has no cure, timely diagnosis and intervention can halt its progression.
“Glaucoma ranks amongst the leading causes of vision impairment and blindness in America, yet it’s estimated that approximately half of those with the condition are unaware of it,” stated Michael F. Chiang, M.D. “Since glaucoma typically presents no warning signs, the only way to determine if one has it is through a comprehensive dilated eye examination. Although there’s no cure, early treatment can significantly help in preserving vision.”
Routine eye examinations are crucial as many individuals may not exhibit symptoms until the disease has reached an advanced stage. Gaining insight into how to identify this condition and understanding the steps to take can be beneficial in safeguarding your eyesight over time.
Glaucoma actually refers to several eye disorders that inflict damage on the optic nerve at the rear of the eye, ultimately leading to vision loss and potential blindness. The most prevalent form in the United States is open-angle glaucoma, while less common variants include angle-closure glaucoma and congenital glaucoma.

Causes
In some cases, glaucoma arises from other health conditions, but this is not universally true. While the exact origins of open-angle glaucoma remain unclear, it is thought to stem from intraocular pressure that escalates when fluid drainage is inadequate. This accumulated pressure can damage the optic nerve over time, leading to vision difficulties.
Risk Factors
Glaucoma is not something that can be avoided and may impact anyone, but certain demographics are at an increased risk. Those aged 60 and above, particularly Hispanic or Latino individuals, face higher chances of developing the condition. Additionally, African American individuals over 40, as well as those with a family history of glaucoma, are at greater risk.
Symptoms
Initially, many individuals do not exhibit any noticeable symptoms of glaucoma. However, as the condition progresses, you might experience changes in your vision, including blind spots or reduced peripheral vision in one or both eyes, often affecting your side vision first. The gradual nature of this vision loss can lead individuals to adapt without recognizing the changes, contributing to the fact that many remain unaware they have glaucoma.
Symptoms such as severe eye pain, nausea, reddened eyes, and blurred vision may indicate angle-closure glaucoma, necessitating immediate medical attention.
Diagnosis
The definitive way to diagnose glaucoma is through a dilated eye examination, which includes visual field testing to evaluate your peripheral vision. This non-invasive procedure allows your doctor to assess how well you can see objects located outside your direct line of sight.
Treatment
If left untreated, glaucoma can ultimately result in blindness. While treatment will not reverse any existing vision impairment, it can prevent further deterioration. Options for treatment often include prescription eye drops aimed at lowering eye pressure. Other methods may involve laser therapy or surgical procedures to facilitate fluid drainage. For those whose daily activities are impacted by vision loss, vision rehabilitation services and devices may offer assistance.
