Homework Answer on Age-Related Macular Degeneration
Macular degeneration, also referred as age-related macular degeneration (AMD or ARMD) is a common and leading eye condition that causes loss of vision among 50 and 50 plus year-old population. This clinical condition damages the macula which is described as a small spot near the center of the retina. The macula is made up of millions of light-sensing cells that provide sharp, central vision(Penfold & Provis, 2005).It is the most sensitive part of the retina, which is located at the back of the eye.
When the macula is damaged, the middle of the field view appears blurry, dark or distorted. Basing on recent epidemiologic information, it has been found that degeneration of the macula may adversely result to the victim suffering from an irreversible loss of vision. Furthermore, according to the National Eye Institute,approximately 2.07 million Americans had advanced age-related macular degeneration in the year 2010. However, the population of those who will suffer from AMD is expected to shoot significantly from 2.07 million people to 5.44 million peopleby the year 2050 (Chakravarthy et al., 2010).
Thus, Age-related macular degeneration has an estimate prevalence of one out of two thousands individuals in the United State of America and other developed countries.Even though macular degeneration isn’t associated with excoriating painsa vast majority of the macula cells are likely to die thus resulting the victim losing proper central and sharp vision.Macular degeneration is caused by either the formation of deposits called drusen under the retinaor due to the growth of abnormal blood vessels under the retina(Holz et al., 2004).
