Glaucoma is the degeneration of the optic nerve that leads to a loss of peripheral vision, then later central vision. It is one of the most common preventable blindness, and many individuals do not even realize they have the condition because it is often asymptomatic. It currently affects over 400,000 Canadians, and 67 million people globally.

The cause of glaucoma is currently unknown, but it has been found to have a strong association with intraocular pressure (eye pressure). The intraocular pressure is determined by the production and outflow of fluid in the anterior portion of the eye. A comprehensive eye examination includes the measurement of intraocular pressure. It is important to note that glaucoma is not always associated with an increase in eye pressure, but it does increase the risk of developing glaucoma. If you have a family history of glaucoma, there’s a greater risk you may develop this eye condition as well.

The main treatment for glaucoma is to achieve a good intraocular pressure control with the use of eye drops or surgeries. To ensure the best prognosis for this condition, early prevention and detection is key. For more information about glaucoma, book an appointment with your optometrist now.
