Understanding Glaucoma Risks and Diagnosis Treatment Options for Glaucoma
Glaucoma is a disease that causes damage to the major nerve of the eye called the optic nerve, a part of the central nervous system that carries visual information from the eye to the brain. The optic nerve is part of the central nervous system and is responsible for transmitting the visual information that allows us to see. Damage to this nerve is permanent and, if left untreated, can lead to irreversible vision loss.
In many cases, glaucoma develops when the pressure inside the eye, known as intraocular pressure (IOP), becomes elevated. This occurs when the eye produces more fluid than it can properly drain. Over time, increased IOP can damage the optic nerve. However, it is important to note that glaucoma can also occur in people with normal eye pressure.
The most common type is primary open-angle glaucoma, affecting approximately 3 million Americans. Other forms of glaucoma include angle-closure (narrow-angle) glaucoma, congenital glaucoma, normal-tension glaucoma, and secondary glaucoma, each with its own causes and treatment considerations.
Glaucoma becomes more common with age. Approximately 2% of Americans over age 50 have glaucoma, increasing to about 4% by age 70 and nearly 10% among those over age 80. Although anyone can develop glaucoma, certain factors increase the risk.
Risk Factors
You may be at increased risk for glaucoma if you have:
- A family history of glaucoma
- African American, Hispanic/Latino, or Asian ancestry
- Diabetes
- Elevated eye pressure (IOP)
- Significant nearsightedness or farsightedness
- Long-term use of steroid medications
- A history of eye injury or trauma
- Age 65 or older
Individuals with one or more of these risk factors should have a comprehensive dilated eye examination every one to two years, or as recommended by their eye care professional.
Early Detection Is Essential
Glaucoma is often called the “silent thief of sight” because it usually develops without pain or noticeable symptoms in its early stages. Many people are unaware they have the disease until permanent vision loss has already occurred.
The good news is that early detection and treatment can significantly reduce the risk of vision loss. While damage caused by glaucoma cannot be reversed, treatment can slow or prevent further progression. Depending on the type and severity of glaucoma, treatment options may include prescription eye drops, laser therapy, or surgical procedures to lower eye pressure and protect the optic nerve.
Regular comprehensive eye exams remain the best defense against glaucoma. Detecting the disease early provides the greatest opportunity to preserve vision and maintain long-term eye health.

Glaucoma: Awareness
You can be diagnosed by your doctor with different types of glaucoma. In the video selection below, each type is defined and includes closed-angle, narrow-angle, open-angle and exfoliation syndrome. Depending on the type you have, your treatment options will differ, so it is important to know which type you have.
