One symptom of macular degeneration is dark areas in your central vision.
With macular degeneration, you may have symptoms such as blurriness, dark areas or distortion in your central vision, and perhaps permanent loss of
your central vision. It usually does not affect your side, or peripheral vision.
What is Macular Degeneration?
Include the formation of deposits called drusen under the retina, and in some cases, the growth of abnormal blood vessels under the retina. With or
without treatment, macular degeneration alone almost never causes total blindness. People with more advanced cases of macular degeneration continue
to have useful vision using their side, or peripheral vision. In many cases, macular degeneration's impact on your vision can be minimal.
Age-related macular degeneration (AMD) is a deterioration or breakdown of the eye's macula. The macula is a small area in the retina — the light-sensitive
tissue lining the back of the eye. The macula is the part of the retina that is responsible for your central vision, allowing you to see fine details
clearly. The macula makes up only a small part of the retina, yet it is much more sensitive to detail than the rest of the retina (called the peripheral
retina). The macula is what allows you to thread a needle, read small print, and read street signs. The peripheral retina gives you side (or peripheral)
vision. If someone is standing off to one side of your vision, your peripheral retina helps you know that person is there by allowing you to see
their general shape.
Many older people develop macular degeneration as part of the body's natural aging process. There are different kinds of macular problems, but the
most common is age-related macular degeneration.
