Are You at Higher Risk for Glaucoma? How Family History and Genetics Play a Role

Glaucoma is often referred to as the “silent thief of sight” because it can gradually damage the optic nerve without causing noticeable symptoms until vision loss has already occurred. While anyone can develop glaucoma, certain individuals are at higher risk, especially those with a family history of the disease. Understanding your genetic risk factors and prioritizing regular eye exams can help protect your vision before it’s too late.
 

How Genetics and Family History Increase Your Risk

If you have a parent, sibling, or close relative diagnosed with glaucoma, your chances of developing it are significantly higher. Research shows that having a first-degree relative with glaucoma can increase your risk up to nine times compared to someone without a family history.
 

Specific genes have also been linked to certain types of glaucoma, especially primary open-angle glaucoma. While scientists are still studying the full genetic picture, it’s clear that both inherited traits and shared environmental factors play a role in how and when glaucoma may develop.
 

Who Else Is at Risk?

In addition to genetic factors, you may be at greater risk for glaucoma if you:

• Are over the age of 60

• Are African American, Hispanic/Latino, or Asian

• Have high eye pressure (intraocular pressure)

• Have thin corneas or abnormal optic nerve anatomy

• Have a history of eye injury or certain medical conditions such as diabetes
   

Even if you don’t currently have symptoms, these risk factors make routine eye care essential.
 

Why Routine Eye Exams Matter

Because glaucoma often progresses without symptoms, early detection is your best defense. A comprehensive eye exam can detect signs of glaucoma well before noticeable vision loss occurs. At Texas State Optical in Humble, our experienced optometrists use advanced imaging tools and visual field testing to monitor your eye health and catch potential issues early.
 

Routine eye exams are especially important if you have a family history of glaucoma. Early intervention, including prescription eye drops or other treatments, can slow or prevent further damage to your optic nerve.
