Canadian Ophthalmological Society promotes global awareness of the leading cause of blindness during World Glaucoma Week

Difficult-to-detect eye disease is known as the ‘silent thief of sight’
TORONTO, March 9, 2021 /CNW/ – A person with glaucoma can lose as much as 40 per cent of their sight without noticeable symptoms and it is the leading cause of irreversible blindness that affects 78 million people worldwide, including over 800,000 Canadians, half of whom don’t even know they have it, according to the Canadian Ophthalmological Society. Now, during World Glaucoma Week, they are sharing a new video about the importance of regular eye exams for detecting what is known as the ‘silent thief of sight.’
“We rely on our sight for everything we do, so the loss of vision has a far-reaching, negative impact on quality of life, particularly among Canada’s aging population for whom this eye disease disproportionately affects,” said Dr. Colin Mann, President of the Canadian Ophthalmological Society. “Raising awareness and encouraging regular testing to prevent vision loss from glaucoma is an important message that Canadians need so they can save their sight before it’s too late.”
Because there are no noticeable symptoms, ongoing monitoring is needed to watch for changes and ophthalmologists may use several tests during an evaluation for glaucoma, a disease that affects the optic nerve. This nerve is what transmits the images you see from the eye to the brain and it is made up of many nerve fibres. When these nerve fibres become damaged by pressure that builds up inside the eye, known as intraocular pressure (IOP), it can cause blind spots and vision loss.
While those older than 60 are six times more likely to get glaucoma, anyone can develop the disease and there are several different factors that can increase your risk, including ethnicity, family history, long-term steroid use, previous eye injuries and certain optic nerve conditions.
Detection & Treatment
By the time it is noticeable, the most common symptoms of glaucoma include the loss of peripheral vision, halos around lights, eye pain and/or redness, and blurred or decreased vision. While it is a chronic eye disease, it can be controlled with proper management.
Treatment options include eye drops or several different medications to decrease the amount of fluid in the eye, increase outflow of fluid from the eye, or reduce the production of fluid, and laser treatments to improve drainage of fluid from the eye. For cases in which eye drops and laser fail to stop the progression of glaucoma, conventional surgery may be recommended to create a new passage for aqueous fluid to leave the eye, including minimally invasive glaucoma surgeries (MIGS), a group of devices/procedures to improve movement of fluid through the eye or reduce fluid production.
