What Is the Cause of the Most Common Type of Glaucoma?

Glaucoma is often referred to as the “silent thief of sight” because it can gradually steal your vision without any warning signs. It’s a group of eye conditions that damage the optic nerve, which is essential for clear vision. This damage is often caused by abnormally high pressure in the eye, though not always. If left untreated, glaucoma can lead to irreversible vision loss or even blindness.
 

Understanding the Most Common Type of Glaucoma

The most common form of glaucoma is primary open-angle glaucoma (POAG). It develops slowly and painlessly over time, making it especially dangerous because many people don’t realize they have it until vision has already been affected.
 

In POAG, the eye’s drainage canals become less efficient over time, causing a gradual increase in intraocular pressure (IOP). Unlike acute forms of glaucoma, this pressure builds slowly and does not present with sudden symptoms, making regular eye exams crucial for early detection.
 

What Causes Primary Open-Angle Glaucoma?

While the exact cause of POAG is still being studied, several contributing factors are known:
 

• Elevated intraocular pressure (IOP): The most significant risk factor. When the fluid in the eye (aqueous humor) doesn’t drain properly, it increases pressure inside the eye.

• Age: The risk increases significantly after age 40.

• Genetics: A family history of glaucoma can increase your risk.

• Ethnicity: African American, Hispanic, and Asian populations have a higher risk.

• Medical conditions: Diabetes, hypertension, and poor blood circulation can contribute to optic nerve damage.

• Eye structure abnormalities: Differences in the drainage angle of the eye may increase risk.

Why Regular Eye Exams Matter

Because POAG progresses so slowly and without symptoms, comprehensive eye exams are the only way to detect it early. At Volusia Eye Associates, we use advanced diagnostic tools to measure eye pressure, examine the optic nerve, and assess your overall eye health. Early detection allows us to begin treatment right away, often with medicated eye drops or laser procedures, to help preserve your vision.
