The Dilemma of Macular Degeneration Essay -- Vision Sight Disorders Es

The Dilemma of Macular Degeneration According to Baily and Hall, time visual impairment early in life is associated with inherited born(p) disorders, abnormal fetal devepment, and problems associated with premature birth, intimately eye conditions are associated with aging. They study that over 70% of the visually impaired population in the unite States is over 65. Age related maculopathy, also called macula lutear decadence, or AMD, impairs the center of deal in older individuals. The macula is the region in the back of the retina that surrounds and includes the fovea centralis (Goldstein 1999). It is important to understand that when this degeneration progresses enough, the condition constitutes blindness because the foveal area is what is apply to focus on something. Most cases do not progress this far, exactly between five and 20% do. Allikments and Shroyer claim that 11 million great deal in the United States alone suffer some degree of this impairment, with 75% of tho se individuals being 75 or older. Seven percent of this older geezerhood group reportedly suffer advanced forms. Freidman reports the disease as most common in developed countries.The high percentages of individuals who endure this impairment justifies and a good deal demands future(a) research because the causes are not fully understood. The need for future research can be better emphasized if those with normal resource try to empathize with victims of macular degeneration. One can only imagine how forestall it must be to receive sensatrions only in the periphery of the retina. Because the macula encompassed the cone rich fovea, which is used to focus on objects, the fovea degenerates as well. This occurence inables individuals to interpret the sensations they experience.
