Understanding the Different Types of Glaucoma and Their Risks

Understanding the Different Types of Glaucoma and Their Risks

Do you only get your eyes checked when you experience discomfort or vision disturbances? Glaucoma, the second most common cause of vision loss after cataracts, does not announce itself loudly, and it can slowly damage your eyes for a long time before the first symptoms appear.

Read on if you want to ensure your eyes are healthy, you have a family history of glaucoma, or you’ve already been diagnosed with it. 

Here, our expert, Dr. Scott Beeve, provides a brief introduction to the various types of glaucoma and the risks associated with each.

Understanding glaucoma

Glaucoma damages the eye due to increased pressure on the optic nerve. The pressure in your eyes increases when the fluid is not drained properly.

As the condition progresses, you may notice headaches, worsening vision, eye pain or pressure, double vision, red eyes, or blind spots.

While the exact cause of glaucoma is not fully understood, increased eye pressure is often linked to genetics, age (people over 60 are at higher risk), and underlying conditions such as diabetes. Women are also at higher risk of developing it.

Glaucoma is not preventable, but it is treatable if diagnosed early and properly managed.

Glaucoma types

While there are several types of glaucoma, it typically falls into three primary categories: open-angle glaucoma, angle-closure glaucoma, and normal-tension glaucoma.

Open-angle glaucoma is the most common type and is caused by poor drainage of eye fluid. The eye’s drainage canals become clogged over time, gradually increasing internal eye pressure. The progression is slow, and you may not know you have it until your vision becomes compromised.

Angle-closure glaucoma is less common but far more aggressive. It occurs when fluid flow is blocked entirely, leading to a sudden, dangerous, and painful spike in eye pressure, which can be a medical emergency.

Normal-tension glaucoma is a less common form of the condition in which optic nerve damage occurs even though eye pressure readings remain within a normal range. Poor blood flow to the optic nerve or increased sensitivity may make some individuals more vulnerable, even without elevated pressure.

Glaucoma risks

All types of glaucoma can lead to vision loss if untreated; however, some forms, such as angle-closure glaucoma, which often presents with severe eye pain, headaches, blurred vision, and nausea, require immediate treatment to preserve vision.

While damage caused by glaucoma cannot be reversed, early detection greatly improves the effectiveness of treatment to manage the condition.
