Treatment has come a long way.


The most common form of glaucoma occurs when the normal fluid pressure inside your eye slowly builds up, causing the fluid to collect and not drain normally. This causes damage to the optic nerve, the bundle of nerve fibers that connects the retina with the brain. Even though glaucoma is normally painless, this damage is irreversible and causes loss of eyesight, including blindness, so timely treatment is critical.

The types of glaucoma:

  • Open-angle, the most common type.
  • Low-tension or normal-tension.
  • Congenital.

One type of glaucoma, called acute angle-closure glaucoma, produces more noticeable symptoms because there is a quick buildup of pressure:

  • Blurred or narrowed field of vision.
  • Severe pain in the eyes.
  • Haloes or “rainbows” around lights.
  • Nausea and/or vomiting.
  • Headache.

If you notice any of these symptoms, get medical attention immediately.

If you think you might have glaucoma, come see us for a complete eye exam. Your UCHealth eye health care provider will take your complete medical history and examine your eyes, and may do the following tests:

  • Visual acuity test: The common eye chart test measures how well you can see at various distances.
  • Refraction: Helps your doctor determine the prescription you might need.
  • Tonometry: This standard test measures the fluid pressure inside the eye.
  • Pupil dilation: The pupil is widened with eye drops to allow a close-up exam of the eye’s retina and optic nerve.
  • Visual field: This test measures your peripheral vision. Lost peripheral vision may indicate glaucoma.
  • Ocular coherence tomography (OCT): This test examines your optic nerve fiber layer, which can help your doctor make a diagnosis.


If you have glaucoma, these tests will help determine which type you have, which in turn helps dictate the treatment you need.

Anyone can develop glaucoma, so you should get regular eye exams. However, some people are at higher risk than others. The risk factors for glaucoma are:

  • Race: Glaucoma is the leading cause of blindness for African-Americans.
  • Age: People ages 60 and older are more at risk for developing glaucoma.
  • Family history: People with a family history of glaucoma are more likely to develop the disease.
  • High fluid pressure inside the eyes: People with a high fluid pressure inside the eyes are at an increased risk.

Anyone in these risk groups should get a complete eye exam on a regular basis.

Glaucoma is a serious condition, but there’s hope. Fortunately, most patients can be helped with drops alone. With early detection and treatment, the chance of losing your vision is very low. Our team approach ensures you’ll get the right treatment for your eyes through:

  • Eye drops.
  • Laser surgery.
  • Additional surgery in rare cases. Our surgeons are experienced in all of these procedures, including minimally invasive glaucoma surgery (MIGS).

Regular eye exams are key

Glaucoma is usually a painless disease, so you should get regular eye checkups even if you don’t have any symptoms. Let us help you keep to a regular eye health schedule, and you can prevent the problems of glaucoma. Your future looks brighter indeed.
