I have two responses for you. George, An acre is a unit of area, it is 43560 square feet, but it can be any shape, a square, a circle, a long thin rectangle, a triangle, pie shaped or any other shape. If it is a square, the sides would be approximately 209 fet long and you would need 4 209 = 836 feet of fencing.
(Redirected from Senile macular degeneration). Macular degeneration, often age-related macular degeneration (AMD or ARMD), is a medical condition that usually affects older adults and results in a loss of vision in the center of the visual field (the macula) because of damage to the retina.It occurs in dry and wet forms.lthough some macular dystrophies affecting younger individuals are sometimes rarely referred to as macular degeneration, the term generally refers to age-related macular degeneration (AMD or ARMD). The retina is a network of visual receptors and nerves.
Age-related macular degeneration (AMD) is a deterioration or breakdown of the eye's macula. The macula is a small area in the retina â 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.
