Glaucoma is a category of eye disorders, that in most cases, are linked to a raised internal eye pressure. It is also possible to have glaucoma with a normal eye pressure, called normal tension glaucoma. The rise in eye pressure can damage the eye’s optic nerve disrupting the transmission of visualĀ  information to the brain. Early stages of untreated glaucoma can include loss of peripheral, or side, vision and further progression without treatment can eventually lead to blindness.

Most cases of glaucoma produce no symptoms at all untilĀ  vision loss occurs. Because of this, many cases go unnoticed until irreversible optical nerve damage has occurred, and some vision has been lost. This is one reason why yearly eye check ups are so important!

At Spectrum Family Eye Care all of our routine eye exams include testing for glaucoma using a machine called a tonometer. The tonometer is used to measure the pressure inside your eye. Visual field testing is another way to determine loss of peripheral vision. It involves staring ahead while holding a button that will allow you to click when you see a flashing light in the edges of your vision. The test catches any blind spots that may develop as a result of damage to the optic nerve as a result of glaucoma.

What causes glaucoma, or, increased eye pressure?

Fluid is constantly being produced and drained on a regular basis inside both of your eyes. The two main reasons why someone would develop an increase in their eye pressure are;

  • Too much fluid is being produced, causing increased pressure.
  • There is a problem with the drainage system of the eye and the fluid is building up, causing increased pressure.

To date the exact reasons of why fluid builds up in the eye are not known.

Risk factors for the development of glaucoma

  • Elevated pressure in the eye
  • Family history
  • Age – after age 40
  • Ethnicity-African Americans tend to have a higher incidence of glaucoma
  • Myopia- people with higher amounts of nearsightedness
  • Diabetes

What is the treatment for glaucoma?

Treatment will depend on the type of glaucoma you have, and the severity. The most common treatment for glaucoma is prescription eye drops to lower the eye pressure and reduce damage to the optic nerve tissue. Other methods may include surgery or the use of lasers to lower the pressure in the eye. Our Optometrists are well trained in the detection of glaucoma, and can put you into the care of highly specialized glaucoma specialists for appropriate treatment.
