Many leading causes of adult-onset vision loss can be prevented
TORONTO, Nov. 21, 2013 /CNW/ - According to the World Health
Organization, 75 per cent of vision loss can be prevented or treated.i Today CNIB is launching a national campaign called "Worth a thousand
words: Preserve your vision" to raise awareness of the impact of adult-onset vision loss and that
many conditions are preventable if diagnosed and treated at an early
The campaign features a unique photo album of images representing key
milestones in an average Canadian's life - a birthday, a graduation, a
wedding. However, the images have been digitally altered so the
milestones are seen as they might be by someone living with either of
two of the leading causes of adult-onset vision loss, wet age-related
macular degeneration (AMD) and diabetic macular edema (DME). The photo
album demonstrates the impact that vision loss can have on the stories
of our lives - past, present and future.
"Every 12 minutes, someone in Canada begins to lose their vision. The
earlier an eye disease is detected, the greater the chance of
preventing or minimizing associated vision loss through treatment,"
says Dr. Keith Gordon, Vice President, Research, at CNIB. A 2012 study
showed one in seven Canadian adults may be living with some form of
vision loss, much of which could be corrected.ii
Many eye diseases develop gradually and have no symptoms in the early
stages until they eventually make themselves known with vision loss.
The ability to perform daily tasks - reading, driving or cooking - is
at risk with the loss of one's vision. However, with proper support,
people who are blind or partially sighted can learn to see beyond
By sharing real stories about people living with wet AMD or DME, the
"Worth a thousand words: Preserve your vision" campaign aims to educate
Canadians and to raise awareness of the importance of eye health and
the impact of vision loss.
"The goal of this photo album is to give sighted individuals an idea of
what the world might look like to those who have two of the most common
conditions that result in adult-onset vision loss - wet age-related
macular degeneration and diabetic macular edema," explains Dr. Gordon.
"It does so by presenting scenes from the lives of everyday Canadians
over the past several decades, but showing them as they might appear to
those experiencing these conditions."
About DME and wet AMD
Diabetic macular edema (DME) is a common complication of diabetic
retinopathy. It is caused by damage to the blood vessels of the retinaiii and is a leading cause of vision loss in the working-age population in
the developed world.iv It is estimated that vision loss resulting from DME affects
approximately 60,000 Canadians, making it a major cause of adult-onset
vision loss in Canada.v
Age-related macular degeneration (AMD) is the leading cause of severe
vision loss for Canadians over the age of 60.vi There are two types, wet and dry. While only 10-15% of AMD cases are of
wet AMD, wet AMD is responsible for 90% of the severe vision loss
caused by AMD.vii Wet AMD is a progressive disease that causes rapid and severe central
vision loss and can severely compromise a person's ability to function
independently. An estimated 1.4 million Canadians have some stage of
AMDviii and a 2011 study estimated that nearly 90,000 Canadians had vision loss
from AMD in 2007.ix It is anticipated that the number people with AMD will double within
the next 25 years due to the ageing of the population.x

support, knowledge and a national voice to ensure Canadians who are
blind or partially sighted have the confidence, skills and
opportunities to fully participate in life. To learn more, visit cnib.ca or call the toll-free CNIB Helpline at 1-800-563-2642.
This CNIB campaign is a collaboration with one of Canada's leading
