Age-Related Macular Degeneration (ARMD)
Age-Related Macular Degeneration (ARMD) is the leading cause of blindness in North America especially over the age of 65. It is the result of an age-related deterioration/degeneration of the tissues of the macula which is the area of the retina at the back of the eye responsible for central detailed vision. Although this is often worse in one eye than the other, it usually occurs in both.
ARMD comes in two forms, the most common is called "dry" ARMD and is characterized by a gradual loss in ability to see clearly and increased vision distortions. Unfortunately, at present there is no effective treatment to restore vision loss due to "dry" ARMD although ongoing research indicates that certain vitamin and mineral supplements may help prevent or slow the progression of ARMD. Use of low vision aids such as telescopes and magnifiers can allow the best use of any residual vision.
Although less common, "wet" ARMD typically results in more severe vision loss. Often it is preceded by the "dry" form. It is due to the growth of new blood vessels in the macular area which leak and eventually leads to scarring with central vision loss. Often the onset of blurry vision with "wet" ARMD can be sudden (within days). With "wet" ARMD, early intervention is important as use of laser treatment, photodynamic therapy and/or newer anti-VEGF treatments may reduce the amount of tissue damage and the resulting vision loss.
