Is Glaucoma Hereditary? What You Need to Know

Glaucoma is one of the leading causes of irreversible vision loss worldwide, often referred to as the “silent thief of sight” because it typically develops without noticeable symptoms in its early stages. Let’s explore what you need to know about the hereditary factors behind glaucoma and what you can do to protect your vision.
 

Understanding Glaucoma

Glaucoma is a group of eye diseases that damage the optic nerve, usually due to elevated eye pressure. If left untreated, this damage can lead to permanent vision loss. The most common types include open-angle glaucoma and angle-closure glaucoma. Early detection is crucial because once vision is lost, it cannot be restored.
 

The Role of Genetics

Research shows that glaucoma often runs in families. If you have a parent, sibling, or grandparent with glaucoma, your risk of developing the condition is significantly higher. Certain types of glaucoma, such as juvenile open-angle glaucoma, are more strongly linked to specific genetic mutations. Even if you don’t experience symptoms, your genetic predisposition means regular screenings are essential.
 

Other Risk Factors

While family history is an important consideration, other risk factors also play a role, including:

• Age: The risk increases after age 40 and rises significantly after age 60.
• Ethnicity: People of African, Asian, and Hispanic descent may have a higher risk.
• Eye Health Conditions: High eye pressure, thin corneas, or a history of severe eye injuries can increase vulnerability.
• Medical Conditions: Diabetes, high blood pressure, and certain systemic diseases may elevate risk.

Why Regular Eye Exams Matter

Because glaucoma often progresses silently, comprehensive eye exams are the only reliable way to catch it early. During an exam, your optometrist can measure eye pressure, evaluate the optic nerve, and perform visual field testing. Detecting glaucoma early allows for timely treatment - such as prescription eye drops, laser therapy, or surgery - to slow or prevent further vision loss.
