Common Vision Conditions

Diabetic Retinopathy

  • Diabetic retinopathy is the most common diabetic eye disease.
  • It is caused by changes in the blood vessels of the retina. In some cases, blood vessels on the retina may swell and leak. In others, new blood vessels may form on the retina.


  • Glaucoma is the second most common cause of vision loss in seniors in Canada.
  • Glaucoma involves damage to the optic nerve most often caused by high pressure inside the eye due to a build up of excess fluid.
  • Over time the disease develops into a loss of peripheral (side) vision (ie. ‘Tunnel vision’)


  • Affects 2.5 million Canadians.
  • With age, your lens hardens and may become cloudy. This in turn, blocks light from reaching the retina and interferes with your vision.
  • Cataracts can be treated with surgery that requires your natural lens to be replaced with an artificial lens.

Age-Related Macular Degeneration

  • AMD is the leading cause of vision loss in Canada.
  • Causes damage to the macula which is the central part of the retina. The macula is responsible for seeing fine details.
  • There are 2 forms of AMD: Dry and Wet (most severe form).
