The macula is the central point in the back of the eye that we use to look straight at something. It is the area that gives us our sharpest vision, in color, and is composed of about 600,000 micro-nerves. Macular degeneration is the dying of these micro-nerves, with a loss of central vision, and is referred to as the dry or wet type.
The wet type means there is some blood leaking into the macula which can cause vision loss quickly due to scar formation as the blood breaks down. The dry type means there is no blood present, but, rather, a plaque present that crowds out the micro-nerves and reduces the macula’s ability to absorb light.
