Can glaucoma be prevented?

18 June 2026

Glaucoma is one of the leading causes of irreversible vision loss worldwide. It is a disease that progressively damages the optic nerve, the structure responsible for transmitting visual information from the eye to the brain.

One of the greatest concerns is that, in most cases, glaucoma does not present symptoms in its early stages. Many people may have the disease for years without noticing changes in their vision, which is why it is often referred to as the “silent thief of sight.”

Can it be prevented?

Although it is not always possible to completely prevent glaucoma, early detection can help avoid or delay vision loss through regular eye examinations.

Early diagnosis is the most effective way to protect vision, as the damage caused by glaucoma cannot be reversed. However, timely treatment can help control the disease and preserve existing vision.

Who is at greater risk?

Certain individuals have a higher risk of developing glaucoma, including:

• Adults over the age of 40.

• People with a family history of glaucoma.

• Patients with elevated eye pressure.

• Individuals with diabetes, high blood pressure, or cardiovascular disease.

• Patients with high myopia (severe nearsightedness).

• People who use certain steroid medications for extended periods.

If you belong to any of these groups, it is especially important to undergo regular eye examinations.

Because glaucoma often progresses silently, routine eye checkups are essential. A comprehensive eye exam can make the difference between preserving vision and experiencing irreversible damage.

Early detection remains the best strategy to combat this disease and protect long-term visual health.
