Glaucoma Testing & Exam

Glaucoma is the Second Most Common Cause of Vision Loss in Canada

Glaucoma Types and Symptoms

Although a cure for glaucoma has not yet been developed, research and technology have made it much easier for eye doctors to detect the symptoms and provide treatments to prevent further damage. When a person undergoes regular glaucoma testing and examination at Apex Vision in Edmonton, their optometrist will examine both eyes carefully for pressure and damage to the optic nerve, which are symptoms of glaucoma. The pressure is caused by a buildup of fluid inside the eye. This fluid is different from tears, which only affect the outside of the eye.

Chronic Glaucoma

A person who develops chronic or open-angle glaucoma is not alone. It is the most common type of glaucoma. It affects the anterior chamber, which is between the white part of the eye, or cornea, and the iris. If a person has chronic glaucoma, this chamber is at a wide or open angle, and there is pressure and damage to the optic nerve. This condition occurs gradually, as clogs build up inside the drainage canals of the eye, pressure builds and the optic nerve sustains damage.

Acute Glaucoma

The angle of the anterior chamber narrows and affects the drainage of the eye’s fluid in acute glaucoma. This condition is not as common in America as it is in Asia. The blockage occurs suddenly with this type of glaucoma, causing obvious and severe symptoms that include severe eye pain, headache, blurred vision and haloes or profuse tearing. A person should seek immediate glaucoma testing in Callingwood at the onset of these symptoms. Farsightedness increases the risk of acute glaucoma because the angles in the eye are narrower. Age also increases the risk because the lens of the eye naturally enlarges, which causes the angle to narrow.

Normal Tension Glaucoma

Some people are at risk for damage to the optic nerve even though the pressure in the eye is within normal range. Factors that indicate risk include family history, Japanese ancestry or systemic heart disease. An eye doctor performing glaucoma testing at Apex Vision in Callingwood would identify this type of glaucoma by looking through the pupil with an ophthalmoscope so that the color and shape of the optic nerve can be examined.

Pediatric Glaucoma

Rarely, a baby’s eye drainage canals may not develop completely during the prenatal period. Enlarged or clouded eyes, excessive tearing and sensitivity to light are signs that parents should seek glaucoma testing in Edmonton for their child. Microsurgery or laser surgery is often successful at correcting this condition.

Important Information about Glaucoma

What happens if Glaucoma is left untreated?

If glaucoma is untreated it could advance to later stages where central vision narrows to “tunnel” vision, or it may result in complete loss of vision according the CNIB.

What are some of the risk factors of Glaucoma?
  • Elevated pressure in the eye
  • Family history
  • Age – after age 40 and after age 60
  • Ethnicity
  • Myopia
  • Diabetes

Be Proactive in Assessing Glaucoma

Early detection of glaucoma is crucial, as most cases present little or no symptoms. Patients often do not know they have it, so it is important to book your annual eye health exams at Apex Vision in Callingwood. They will monitor any changes year over year, especially as your eyes age, to ensure they are catching any early signs of eye disease and recommending preventative treatment.
