Macular degeneration is generally an age-related loss of sight in the middle of the field of vision. There are two kinds – the more common and less severe dry macular degeneration is the deterioration of the macula, the layer of tissue on the inside back wall of the eyeball. Wet macular degeneration is a more severe condition where blood vessels grow under the retina and leak fluid and blood. Dry macular degeneration symptoms may develop gradually, and include the need for brighter light, a blind spot in the middle of the field of vision, and a fading of color intensity.
