What is AMD?

It’s February, time for Valentine’s Day and for Macular Degeneration and Low Vision Awareness Month. Age-Related Macular Degeneration (AMD) is one of the leading causes of vision loss in Canadians over the age of 50 and most people probably know someone affected by this disease. Macular degeneration is a loss of central vision caused by damage to the macula, the part of the retina responsible for sharp vision. There are two types of AMD. The more common Dry AMD is characterized by deposits forming on the retina that slowly start to blur the central vision. This can cause straight lines to appear slanted or broken. Wet AMD is caused by abnormal blood vessels growing under the retina that leak and cause fluid accumulation, which further distorts the vision. This impacts a person’s ability to perform their daily life activities such as recognize faces, reading and writing.

Risk Factors

There is no definite cause of AMD however, some other determined risks factors are high blood pressure, high cholesterol, smoking, obesity, age and family history. Currently, there is no cure for AMD, however Wet AMD can be treated with injections to stop or delay the progression of vision loss. AMD does not cause total vision loss and only affects the central vision in most people while, patients diagnosed with AMD are often recommended to take vitamins containing Lutein, an anti-oxidant, proven to slow disease progression.

Copping with AMD

Low vision is defined as a visual impairment that is not correctable with glasses, surgery or medications, it also can cause blurred vision, blind spots, tunnel vision or blindness. Patients use specific low vision devices such as magnifiers, telescopes or special glasses to overcome some of their challenges. Your optometrist will be able to guide you in the right direction regarding treatment options and visit schedules. There are also many services available at the CNIB for people who are currently dealing with low vision problems.
