Glaucoma Symptoms: Early Signs to Be Aware of

Dec 27, 2021 | Blog Article, Eye Diseases, Glaucoma

Glaucoma is a group of eye conditions related to abnormally high pressure inside the eye that leads to optic nerve damage. As a result of this damage, people with glaucoma can gradually go blind. In fact, glaucoma is the second leading cause of blindness in the world.1

The Different Signs of Glaucoma

Because glaucoma tends to be a progressive disease, the sooner you can recognize the symptoms of glaucoma, the better off you will be. While there is no cure, early intervention can help manage the eye disease and slow down the negative effects.

Although glaucoma can result in serious damage to eyesight, the early signs of glaucoma are not always easy to recognize. There are also different types of glaucoma with their own symptoms.

Open-Angle Glaucoma Symptoms

Open-angle glaucoma also sometimes called primary or chronic glaucoma is the most common type of glaucoma and is caused by a gradual clogging of the drainage canals in the eyes.

Symptoms of open-angle glaucoma include:

  • Blind spots
  • Tunnel vision

Unfortunately, because there are few symptoms in the early stages, most people do not realize they have open-angle glaucoma until they are already experiencing significant vision problems.

Acute Angle-Closure Glaucoma Symptoms

Acute angle-closure glaucoma also known as narrow-angle glaucoma is a result of sudden fluid build up in the eye and develops quickly.

Acute angle-closure glaucoma symptoms include:

  • Eye redness
  • Blurry vision
  • Eye pain
  • Headaches
  • Nausea and vomiting

If you are experiencing these symptoms, you should get medical attention immediately. Without treatment, blindness could develop after just a few days.

Normal Tension Glaucoma Symptoms

In normal tension glaucoma, eye pressure is normal, but the optic nerve still becomes damaged.

Signs of normal tension glaucoma include:

  • Gradual peripheral vision loss
  • Tunnel vision as the disease progresses

Other Glaucoma Symptoms

In some cases, this disease may be the result of another medical condition and symptoms of glaucoma in eyes will vary depending on the circumstances.

These less common forms of glaucoma may have symptoms such as:

  • Eye redness
  • Eye pain
  • Blurry vision
  • Seeing halos around lights

What to Do If You Are Showing Signs of Glaucoma

If you suspect you are exhibiting any glaucoma symptoms, it is important to get your eyes checked immediately. In some cases, there may be no early signs of glaucoma so getting an exam regularly could help you catch this disease before damage gets too severe. A comprehensive eye exam could also diagnose other eye problems or rule out other eye diseases.

If you are diagnosed with glaucoma, your doctor will work toward developing a treatment plan. Depending on your situation and the type, glaucoma treatment may include medications or surgery.

Whether or not you are experiencing any eye problems, you should get your eyes checked regularly to avoid serious and permanent damage. Contact us to make an appointment at our Blue Island, IL office today.
