Glaucoma do you have the silent thief of sight?
Glaucoma is a group of eye diseases that slowly damage the optic nerve, the part of the eye that carries the images you see to the brain. Once damaged, irreversible blind spots will develop, resulting in less peripheral (side) vision and potentially blindness. (World Glaucoma Association) It is on the World Health Organization list of priority eye diseases. World Glaucoma week is March 12 – 18.
During the week of March 12th there is a concerted effort, organizing a wide range of publicity-seeking activities around the world, involving ophthalmologists, optometrists, eye care workers, hospitals, universities, clinics, private practices and many private individuals.
Glaucoma is the leading cause of preventable blindness worldwide and the first for irreversible loss of vision. It is the second cause of blindness worldwide, according to the World health organization. It is insidious, that’s why it’s called ‘’the silent or sneak thief of sight’’ and can affect anybody. (More than 409,000 people in Canada, 70 million worldwide) And the numbers are growing.
Generally, it does not present symptoms at its onset, therefore many of its victims (over 50%of people affected) do not know they have it. That is why regular eye check-ups are so important (optometrist are well versed in screening)
Early detection is important mainly because glaucoma is a disease that can be controlled with the use of medications, laser treatments, surgery and of course, regular visits to your eye-care specialist.
Some risk factors include being over age 45 (2.5% of the population affected and that goes up to about 11% when you get in the plus 80 age group). Heredity can be another factor, (so check family history) high intra-ocular pressures, vascular diseases and more. Glaucoma is also more prevalent with people of African descent and Hispanics. Asians, on the other hand, are more likely to develop what is called ‘’narrow angle glaucoma’’. Some studies show as well that, people with diabetes are three times more likely to develop glaucoma than the general population age 40 and more.
