Is Glaucoma Hereditary? Understanding Your Risk Factors

Glaucoma is one of the leading causes of irreversible blindness worldwide. Often called the "silent thief of sight," this eye disease develops gradually and typically without noticeable symptoms in the early stages. One of the most significant risk factors for glaucoma is family history, making it important to understand whether glaucoma is hereditary and how it could impact your vision.

Is Glaucoma Hereditary?

Yes, glaucoma can be hereditary. If you have a parent, sibling, or grandparent who has been diagnosed with glaucoma, your chances of developing the disease are significantly higher. The most common form (primary open-angle glaucoma) has a strong genetic component. Research shows that individuals with a family history of glaucoma are up to nine times more likely to develop the condition themselves.

While genetics play a major role, heredity is not the only factor. Age, race, eye pressure, and certain medical conditions such as diabetes or hypertension can also increase your risk.

Who Is Most at Risk?

You may be at a greater risk of developing glaucoma if you:

Have a family history of glaucoma

Are over the age of 60

Are African American, Hispanic, or Asian

Have high intraocular pressure (IOP)

Have certain health conditions like diabetes or high blood pressure

Have experienced eye injuries or undergone certain eye surgeries

Understanding these risk factors can help you take a proactive role in protecting your eye health.

Why Routine Eye Exams Matter

Because glaucoma typically doesn’t present symptoms until vision loss occurs, the only way to detect it early is through a comprehensive eye exam. At San Marcos Vision Center, we use advanced diagnostic tools to assess eye pressure, examine the optic nerve, and measure your field of vision. Early detection allows for timely treatment that can slow or even halt the progression of the disease, preserving your eyesight.

Routine eye exams are especially critical if you have a family history of glaucoma. Even if you feel your vision is fine, underlying damage may already be occurring. Detecting glaucoma early can make a significant difference in treatment outcomes.

Protect Your Sight at San Marcos Vision Center

While glaucoma is indeed hereditary, early detection through routine eye exams is your best defense. If you have a family history of glaucoma or fall into other high-risk categories, don’t wait until symptoms appear. Proactive care can protect your vision and help you maintain your quality of life.
