Protect Your Sight: Understanding Glaucoma Risk Factors

Glaucoma is a group of eye diseases that damage the optic nerve, often due to high pressure inside the eye (intraocular pressure). It’s one of the leading causes of irreversible vision loss and blindness worldwide.

Anyone can develop glaucoma, but some people have a higher risk than others. Knowing your risk—especially what you can control—can help you protect your sight for longer.

Risk Factors for Glaucoma:

• Age: Your risk increases as you get older, especially after age 60.
• Family history: Glaucoma tends to run in families. If an immediate family member, such as a parent or sibling, has glaucoma, your risk may be much higher.
• Race and ethnicity: People of Hispanic, Asian, Native American, and African descent are also at increased risk for certain types of glaucoma. For African Americans, the risk starts rising at an earlier age (around age 40).
• Being a woman: Experts believe this is due to sex-related differences in eye anatomy.
• Eye conditions that carry increased risk:
  • Thin central corneal
  • Nearsightedness (myopia)
  • Farsightedness (hyperopia)
  • Past eye injury
• Certain medical conditions: Diabetes, high blood pressure, and heart disease are linked to higher glaucoma risk. Managing these through lifestyle changes and medication may help reduce your risk.
• Certain medications: Long-term use of corticosteroids has been linked to increased eye pressure.
• Lifestyle choices: Some research suggests that poor sleep, smoking, or an unhealthy diet may affect eye pressure or blood flow to the optic nerve.

Why Risk Factors Matter

Glaucoma is called the “silent thief of sight” because it typically has no symptoms in its early stages but causes irreversible damage. Understanding your risk is essential because:

• Vision loss starts slowly and gradually—often with peripheral (side) vision.
• Many people don’t notice changes until after significant damage has happened.
• Glaucoma often affects both eyes, but pressure may rise in one eye first.
• Sight lost from glaucoma cannot be restored, but early detection can help preserve remaining vision.

Take Charge of Your Eye Health

You can’t change your age or family history, but you can take steps to protect your sight:

• Talk to your eye doctor about your personal risk factors and any changes or concerns you have about your vision.
• Manage conditions that increase your risk, such as diabetes and high blood pressure.
• Stay active, eat well, and avoid tobacco to support eye health.
• Always talk to your doctor before using steroid medications.
• Stick to your recommended eye exam schedule.

Protect your vision by staying informed, and make regular eye exams a priority.
