Primary Location




Glaucoma is a very serious condition of the eye. Without treatment, it can result in permanent vision loss. Some people do not know that they have glaucoma because some forms of glaucoma usually does not show any signs. That is why you show make an appointment with Spectrum Eye Physicians in San Jose, Cupertino, Los Gatos, and Santa Cruz. In our optometry care, we have optometrists and ophthalmologists that work together in providing you the necessary treatment to help manage glaucoma.


What Is Glaucoma?

Glaucoma occurs when there is increased pressure in your eyes. Over time, the increase in pressure can cause permanent and irreversible damage to your optic nerve. When the damage occurs, it can cause the loss of your peripheral (side vision). If left untreated, it can result in blindness.

What Are the Early Symptoms Of Glaucoma?

There are two types of glaucoma. Open-angle glaucoma is the most common. It occurs when the eye doesn't drain fluid the way that it should, resulting in a build-up of pressure. This type of glaucoma shows no early symptoms. It isn't until permanent vision loss has occurred that you will experience any symptoms. This is why annual eye exams are crucial.

The second type of glaucoma is closed-angle glaucoma. This type occurs when the iris blocks up the drainage angle, causing the pressure in your eyes to increase. The symptoms of this type of glaucoma come on suddenly, often right when the pressure in your eye first increases. The symptoms include:

  • Sudden severe pain in the eye
  • A severe headache
  • Nausea
  • Vomiting
  • Seeing rainbow halos around lights
  • Sudden onset of blurry vision

Without immediate treatment, this type of glaucoma can cause blindness.

How Is Glaucoma Diagnosed?

Glaucoma can be detected during your annual eye exam. During a comprehensive eye exam, your optometrist will check the pressure in your eye. If the pressure is elevated, they will dilate your eye to examine your optic nerve for damage.

To determine the type of glaucoma that you have, our optometrist will put a contact lens with a mirror on your eye. If the angle between the iris and cornea is blocked and closed, you have closed-angle glaucoma. If it is open and wide, you have open-angle glaucoma.

Our optometrist may want to take photos of your optic nerve so that they can track the progression of the disease. To gauge your peripheral vision loss, they may order a visual field test.

Because glaucoma is such a serious condition and the most common type shows no early symptoms, you should schedule an appointment with Spectrum Eye Physicians ever year. We treat patients in San Jose, Cupertino, Los Gatos, and Santa Cruz. During your exam, our doctors of optometry will check the pressure in your eye so they can diagnose your condition early.  Call us today at 408-884-2215.
