Macular degeneration is the leading cause of severe vision loss in adults over 60. The macula is a small, but important area in the retina that we use to see details of an object straight ahead. When that part of your eye begins to wear down or blood vessels grow beneath it, blind spots will occur in your central vision. A routine eye exam can detect macular degeneration. There are treatment plans that can help slow the condition or make it less severe.
