Macular degeneration

There are many eye diseases and disorders, some mild to very severe. One example of a disease would be Macular Degeneration. Macular Degeneration is the deterioration of the central portion of the retina, known as the macula. This disease is the leading cause of blindness in people of the age of 55. There are two types of Macular Degeneration, dry and wet. Dry (atrophic), when small yellow deposits form under the macula, causing it the thin and dry out, leading to central vision loss. Wet is…

known to stand out the most. It is unclear how much drusen effects the development of macular degeneration. In some cases, there can be a little amount of drusen with a greater amount of visual damage, or there is a lot of drusen present and the vision may not be that bad. Drusen are infamous for being inconsistant. (Kanski, 1992). Non-exudative (dry) is by far the most common type of age-related macular degeneration. Typically it causes a mild to moderate impairment of vision over several…

Summary The majority of diseases that cause substantial and irreversible vision loss resulting from pathologic ocular neovascularization such as age-related macular degeneration, diabetic retinopathy, retinopathy of prematurity and ocular tumours. Poor drug delivery to lesions in patient’s eyes is a major obstacle to the treatment. Nanotechnology provides novel opportunities to overcome the limitations of conventional drug delivery systems to reach the back of the eye through fabrication of…

and Macular Degeneration According to the American Macular Degeneration Foundation, "macular degeneration is the leading cause of vision loss, affecting more than 10 million Americans - more than cataracts and glaucoma combined." It is currently incurable. Macular degeneration affects more than a third of seniors over the age of 75. Carl Kupfer, the former Director of the National Eye Institute, notes that unless a breakthrough is made in identification and treatment, macular degeneration…

age-related macular degeneration treatments may prevent severe vision loss or slow the progression of the disease considerably. Several treatment options are available, including: Anti-vascular endothelial…

Age-Related Macular Degeneration (AMD) is the most important cause of blindness in industrialized countries. The onset of macular neovascularization in AMD defines an advanced form of the disease characterized by exudative retinal changes due to an abnormal growth of newly formed vessels within the macula. This neovascularization has been divided into three types. Ref gass e ref freunf Type 1 and 2 neovascularization arise from the choroidal circulation and are refered to as choroidal…

Dues Paying Blindness The phone rings around 7:30 on a cool, breezy night in early June, and since the Talking Caller ID announces, “Call from … Mom,” Tracy Greene answers the landline, which he keeps because his mother Helen Greene is 88 and several months, and she does not know his cell number offhand and probably never will. He has been sitting around the apartment binge-watching Season Three of The Walking Dead on Netflix in his white tank top and blue striped boxers for the better part of…

Introduction: Age related change is one of the most common causes of vision loss around the world, affecting between 30 to 50 million people worldwide. As suggestive of the name, age-related macular degeneration (AMD) is most prevalent in adults over the age of 60. Of the cases of AMD, about 90 percent are dry AMD for which no effective treatment exists [1]. The retina is the nerve tissue lining the inside of the eye which begins the conversion of light into vision. The macula,…

It is also caused by multiple visual system disorders like coloboma, retinoschisis, uveitis, lattice degeneration and retinopathy of prematurity. This problem can emerge at any stage from childhood to adulthood and elder age. Often the cause of retinal detachment is found associated with congenital malformations. According to epidemiologic data, it is suggested…

People rarely lose all of their vision from age-related macular degeneration. They may have poor central vision, but they are still able to perform many normal daily activities. Macular degeneration does not seem to affect a person’s life expectancy, but it does seem to affect a person's lifestyle. If a person develops AMD, they should expect a change in diet and everyday activities. To reduce the risk of further vision loss from AMD, a diet rich in green, leafy vegetables, fresh fruit, and fish…
