Neither type causes pain. There are different kinds of macular problems, but the most common is age-related macular degeneration.
Recent years have brought a wealth of new scientific understanding regarding the physiology of this disease. Other, rarer types of muscular dystrophy have been identified, including a distal type that begins in the peripheral muscles of the extremities and one that affects only muscles of the eye.
These new blood vessels leak fluid or blood and blur central vision.
Following are some common ways vision loss is detected: Muscle deterioration starts in childhood or early adulthood but it may proceed very gradually over a number of years, sometimes until late in life.
