Age Related Macular Degeneration (AMD)
Age related macular degeneration (AMD) is the break down of the retina. The retina is the light sensitive layer on the back of the eye. The center of the retina, called the macula, is comprised mostly of cones. The cones provide sharp, central, and color vision. Breakdown of the retina is caused by the natural process of age. AMD is classified into two types of macular degeneration. The less severe of the two is called nonexudative AMD, also known as the dry form. The other form is called exudative AMD, and is known as the wet form.
Nonexudative macular degeneration is deposits of yellowish white drusen usually localized in the macular region of the retina. These deposits are formed from the natural breakdown of the retina. Symptoms include, if any, mild distortion, blurriness, or vision loss. Due to the area affected by the drusen, some people complain of central, near, and sharp vision being affected. There is no treatment for this form of macular degeneration. It is recommended by ophthalmologists to exercise, eat dark green leafy vegetables, and to take vitamins rich in zinc, lutein, and omega 3.
Exudative macular degeneration is when the retina produces extra blood vessels in the eye. This happens when the retina feels that the blood vessels it currently has do not perform as they should. The bad thing about the retina producing more blood vessels is that the blood vessels are weak and therefore break. When the blood vessels break, blood pools out and causes several problems, such as swelling and scarring.
Some people notice a dark area in the center of vision and straight objects have a wave in them, such as telephone poles or fences. If not treated promptly vision will be lost. Unlike nonexudative macular degeneration, there are several different treatments for this form. Your ophthalmologist will tell you which treatment is right for you It is recommended by ophthalmologists to check your vision daily with an Amsler Grid, exercise, eat dark green leafy vegetables, and to take vitamins rich in zinc, lutein, and omega 3.
