Glaucoma Q & A

Cascade Vision Center

What is glaucoma?

Glaucoma is a disease in which fluid builds up in your eye, putting pressure on and causing damage to your optic nerve. If left untreated, glaucoma can cause irreversible damage that leads to loss of vision.

There are two main types of glaucoma, open-angle glaucoma and angle-closure glaucoma. Most people have open-angle glaucoma, which happens when fluid doesn’t drain properly from the eye. Angle-closure glaucoma is less common and occurs when the drainage canal in your eye located between your iris and cornea becomes too narrow for fluids to flow out.

What are common symptoms of glaucoma?

People don’t usually experience any symptoms in the early stages of glaucoma. However, optometrists screen for glaucoma during annual eye exams for early detection.

It’s important to get annual exams because symptoms of glaucoma don’t usually appear until there’s a dangerous level of fluid buildup in your eye. If you’re experiencing an acute glaucoma attack, it’s important to seek emergency medical care. Symptoms might include:

  • Loss of vision
  • Eye pain
  • Seeing light halos around objects
  • Blurry vision

The doctors at Cascade Vision Center are on call 24/7 for emergency eye care and provide same-day emergency care for issues such as acute glaucoma attacks.

How is glaucoma diagnosed?

During your annual eye exam, your doctor routinely screens for glaucoma using two primary tests. The first, tonometry, tests your inner eye pressure. During this test, your eye is numbed using drops, and the eye pressure is tested using a tonometer. The second, ophthalmoscopy, allows your doctor to examine the shape and color of your optic nerve by dilating your eye.


If your doctor suspects during a routine screening that you might have glaucoma, they may perform additional tests to confirm the diagnosis as needed. Cascade Vision Center uses cutting-edge high-definition imaging and testing to confirm a glaucoma diagnosis.

How is glaucoma treated?

Glaucoma is treated through a number of different methods, depending on how far its progressed. The team at Cascade Vision Center generally treats glaucoma through the use of prescription eye drops to decrease your eye pressure. However, more advanced stages of glaucoma treatment may include the following:  

  • Medication
  • Laser surgery
  • Eye surgery

The team at Cascade Vision Center has the expertise to guide you through the appropriate steps of screening and treatment for glaucoma to prevent vision loss. Call the office or make an appointment online today for your consultation.
