WebCone-rod dystrophy is a group of related eye disorders that causes vision loss, which becomes more severe over time. These disorders affect the retina, which is the layer of light-sensitive tissue at the back of the eye. In people with cone-rod dystrophy, vision loss occurs as the light-sensing cells of the retina gradually deteriorate. WebThe macula (and the rest of your retina) is made of photoreceptor cells. Rods are photoreceptors that process black and white light. They also help you see at night and in dim light. Cones process color and make up most of your usual vision. Both types of cells work together to give a clear, accurate picture of what you’re seeing.
