Age Related Macular Degeneration (AMD) - 1653 Words

Review: Age related macular degeneration (AMD) is the leading cause of blindness in people over the age of 50. Every ten years after the age of 50 the prevalence of this disease increases exponentially. Many different factors contribute to the development of AMD including genetic, environment, and metabolic functions. Aside from smoking, abnormal blood pressure, and an unhealthy diet low in fruits and vegetables, many more studies are concluding that similar inflammatory and oxidative processes seen in other age related diseases are also playing a key role in the development of AMD. This disease affects the central areas of the retina and choroid. In return central vision is impaired while peripheral vision is usually not lost. AMD is seen in two different forms, the earlier nonneovascular (dry) type and the more advanced neovascular (wet) type. Each form has its own specific pathology and unique characteristics that set them apart. Fatty, protein deposits called drusens may be the k ey risk factor in understanding dry AMD pathology, progression, and treatment. Once the more advanced wet AMD is diagnosed, pathology and treatment are targeted around the formation and destruction of abnormal blood vessels, characteristic of the wet AMD eye. The increasing prevalence of AMD has influenced more investigation into what factors can be modulated to prevent the onset or to stop the progression of AMD. This text will discuss the pathology of drusens and the role of inflammation andShow MoreRelatedAge Related Macular Degeneration ( Amd )1786 Words   |  8 PagesAge-related macular degeneration (AMD) is a clinical condition in which there is a progressive decrease in central vision. There are two forms of macular degeneration, dry/nonexudative and wet/exudative, and these differ in fundal findings and treatment options. Dry macular degeneration is due to accumulation of drusen between the retinal pigment epithelium and Bruch’s membrane and eventually progresses t o geographic atrophy. Geographic atrophy refers to loss of retinal pigment epithelium (RPE)Read MoreAge-Related Macular Degeneration Leads to Severe Vision and Blindnes in Our Elderly711 Words   |  3 PagesAge-related macular degeneration also known as AMD is a disease leading to severe vision and legal blindness in the elderly population. I will address the health condition description and the disability and functional implications who suffer from this disease. For the health condition description of age-related macular degeneration I will discuss the etiology, onset, prevalence rate, body systems, body structures, and associated deficits that come and are associated with this disease. â€Å"AMD is theRead MoreThe Effects Of Age Related Macular Degeneration Essay2166 Words   |  9 PagesAbstract: â€Å"Age-related macular degeneration (AMD) specifically affects the macular region of the central retina, where both ganglion cells and cones are present at very high densities.† (Penfold Provis, 2005). In this paper, the origins and effects of macular degeneration, both Age-related (usually expressed in adults over 50) and Juvenile (occurring in the teens and early 20’s) are analyzed and discussed.

Retina sends images via the optic nerve from the eye to the brain. Macula is another name for retina’s central portion and is responsible for focusing central vision in the eye. This controls person’s capability to read, drive a ca, recognizes faces or colors.

An essential refractive surface, and fully developed by the age of two (2) (Stein. H et al., 2013), the cornea is a thin clear structure, making up the forefront of the eye, and is the first solid structure light encounters on its path to the brain. Connected to the cornea and adding to the posterior continuityRead MoreNeovascular Age-Related Eye Disease Study1211 Words   |  5 Pageslong-chain polyunsaturated fatty acid intake (LCPUFA) on neovascular age-related macular degeneration (NV AMD) and central geographic atrophy (CGA) over a 12 year intake was studied through a prospective cohort study. The cohort was from the Age-Related Eye Disease Study (AREDS), which is a large phase 3 clinical trial that has tested nutrient and vitamin supplement formulations as prevention methods for AMD. Categories of AMD and risk of progression were determined by the size and extent of drusenRead More The Dilemma of Macular Degeneration Essay2270 Words   |  10 PagesThe Dilemma of Macular De generation According to Baily and Hall, while visual impairment early in life is associated with inherited congenital disorders, abnormal fetal devepment, and problems associated with premature birth, most eye conditions are associated with aging. They claim that over 70% of the visually impaired population in the United States is over 65. Age related maculopathy, also called macular degeneration, or AMD, impairs the center of vision in older individuals.

Furthermore, another part of the eye affected by ultraviolet radiation is the lens and the eye disease in this part is a cataract, which cataract disease is caused by degeneration of the lens and symptoms with a blurred vision as a fog, hindering the light to pass into the eyes and the optic nerves are fully.

AMD can be divided into two categories: atrophic (as known as dry AMD, 90% prevalence) and exudative (wet AMD, more severe) AMD. Dry AMD is a consequence of drusen accumulation, and the wet form is associated with abnormal angiogenesis (Figure 3). Currently
