What Is Glaucoma?
Glaucoma is an eye disease that can cause vision loss. It happens when high eye pressure damages the optic nerve. The optic nerve sends images from your eye to your brain. Without treatment, glaucoma can lead to blindness. According to the World Health Organization, glaucoma is a leading cause of blindness worldwide. Many people do not notice symptoms until the disease is advanced. Therefore, regular eye exams are important.
Understanding Eye Pressure
Eye pressure, also called intraocular pressure, is the force inside your eye. Your eye makes a clear fluid that flows in and out. When this fluid does not drain well, pressure builds up. As a result, high eye pressure can harm the optic nerve. However, not everyone with high eye pressure gets glaucoma. Still, it is a major risk factor for the disease.
How Eye Pressure Affects the Optic Nerve
When eye pressure stays high, it presses on the optic nerve. Over time, this pressure damages the nerve fibers. Because the optic nerve is vital for vision, damage can cause permanent vision loss. In most cases, the damage starts at the edges of your vision. Eventually, it can affect central vision too. For example, you may not notice small blind spots at first. But as the damage grows, vision loss becomes more obvious.
Symptoms and Warning Signs
Glaucoma is often called the “silent thief of sight.” Many people do not feel pain or notice changes early on. Still, some warning signs may appear, such as:
If you notice any of these symptoms, you should see an eye doctor right away. Early treatment can help prevent further optic nerve damage.
Diagnosis and Monitoring
Doctors use several tests to check for glaucoma and optic nerve damage. For instance, they may:
Because glaucoma can get worse without symptoms, regular eye exams are key. The Centers for Disease Control and Prevention (CDC) recommends eye checks, especially if you are over 40 or have a family history of glaucoma.
Treatment Options
There are several ways to lower eye pressure and protect the optic nerve. Treatment options for glaucoma include:
Although treatment cannot restore lost vision, it can slow or stop further damage. Therefore, it is important to follow your doctor’s advice and use your medicines as directed.
Prevention and Eye Health Tips
While you cannot always prevent glaucoma, you can lower your risk. Here are some tips for healthy eyes:
In summary, early detection and care can help prevent vision loss from glaucoma.
