Extractions: Age related macular degeneration (AMD) is a disease that affects the macula, a part of the retina that allows you to see straight ahead and in fine detail. AMD is the most common cause of blindness because its main risk factor is age. Other risk factors include people who smoke, people who have bad eating habits and are obese, people of white race, family history of AMD, and women have greater risk of developing AMD. Dry AMD, the most common type, occurs when light-sensitive cells in the macula degrade and central vision begins to slowly fade. Dry AMD has three stages. Early AMD, the first stage, has a presence of drusens, yellow deposits under the retina, but usually no vision loss or problem is detected. In Intermediate AMD, there are many medium sized drusens or large sized drusens present. In this stage, blurry areas may be present and it is more difficult to do regular task. In Advanced Dry AMD, the light-sensitive cells begin to degrade dramatically and a blurred spot may appear in the central of your vision. Atrophy may also be a factor in advanced stages. This spot may appear larger and become darker and it becomes almost impossible to see with clarity and detail. Dry AMD can evolve into Wet AMD. Wet AMD is more severe and vision loss occurs more rapidly. In wet AMD, small, abnormal blood vessels form. These new blood vessels are very thin and fragile and will begin to break and leak. The blood and fluids eventually causes damage to the macula and causes rapid loss in vision. Although Wet AMD is less common, loss of vision occurs faster so it is essential to get it diagnosed as quickly as possible.

Eye Health Macular Degeneration printable page Macular degeneration accounts for almost 50% of all visual impairment in the developed world. It usually affects people over 50 years of age and is known as Age-related Macular Degeneration (ARMD or AMD). There are other forms of macular disease which affect younger people, which are often termed 'macular dystrophy' and may run in families - however, this type of macular degeneration is rare. Macular degeneration can also be caused by eye injury, infection or inflammation. Diabetes can also cause macular disease (known as diabetic retinopathy). If detected early enough laser treatment can be effective in arresting AMD in a minority of patients. For the majority of patients, however, it remains untreatable. Initially only one eye may be affected and symptoms in the early stages may not be noticed since one good eye can mask the sight problem of the other eye. You may notice: The central part of your vision is 'reduced'. You may see the outline of a face but not the features

Extractions: 1 888 357-0477 or 1 702 515-1084 In the spring of 1971, I was told that I would go blind. The doctor that identified the genetic defect declared he hoped going blind would have a maturing affect. The news that I was legally blind at that time, aged me way beyond my twenty five years. The diagnosis of retinitis pigmentosa, complicated by macular degeneration, usually affecting older people, aged me even further. I was told that I had the eyes of someone in their 80's. Both conditions typically steal precious sight. Conventional medicine had nothing, not even hope to offer. Since then and for over twenty-five years, I have been on a collision course with conventional medical beliefs. Repeatedly told that there was nothing to do for my own impending blindness, or for the predicted loss of my children's sight, I refused to give up. Since conventional medicine had nothing to offer, I turned to the alternative health community. My perceived curse turned into a gift. A new world of hope and help opened when I entered the alternative health care field. In 1979, I earned my Ph.D. in Holistic Health Science from Columbia Pacific University for my work in alternative eye health care. Contrary to conventional medical beliefs, my sight improved. Because so many people are in need, and due to my own success, I've had the privilege to teach these methods all over the world.

Extractions: Macular Degeneration As we age, the macula (the small part of the retina at the back of the eye that provides sharpness of vision) begins to break down and produces small white particles called drusen, which are seen in a fundus photograph and in a cross-sectional diagram above. These can be an early sign of macular degeneration, but they do not usually cause vision loss by themselves and not all patients who develop drusen go on to develop macular degeneration. The dry or atrophic form of age-related macular degeneration, seen above in fundus photography and in a cross-sectional diagram, is the most common form of macular degeneration, accounting for about 90 percent of cases. Although this form of macular degeneration does not usually cause severe vision loss, it can progress to the wet form, so patients who have it should see their ophthalmologist regularly. The wet or exudative form of macular degeneration , seen here in fundus photography and in a cross-sectional diagram, affects about 10 percent of macular degeneration patients. Wet macular degeneration is caused by the growth of abnormal blood vessels at the back of the eye that can leak fluid and blood. wet macular degeneration typically causes significant vision problems in the affected eye and can progress very rapidly and cause permanent vision loss.
Extractions: Subscribe now >> Age-related macular degeneration (AMD) is a progressive disease of the eye occurring in people over 55 years old due to the aging process. The macula is the central part of the retina which lines the inner wall of the eye and provides central vision. In AMD, damage to the macula results in loss of central vision and affects a person's ability to read, recognize faces or drive. The peripheral vision is usually spared. Up to 30 million people worldwide have AMD. Up to 200,000 people in the US are diagnosed with AMD each year. It is the leading cause of blindness in older populations in the US. As we live longer and longer, we will see an increase in AMD. AMD is associated with aging, fair skin, light iris color, hypertension, smoking, arteriosclerosis, prolonged exposure to sunlight, and family history of AMD. There are 2 types of AMD: the "dry" form and the "wet" form, based on the absence or the presence of abnormal growth of blood vessels under the retina. Most people with AMD have the dry form. Currently there is no proven treatment for the dry type, but the loss of vision tends to be milder and the disease progression is rather slow.

Extractions: Harvard Health Publications ... Harvard Medicine Home Macular degeneration is a common cause of blindness and vision impairment among people older than 50 in the United States. This condition also is called age-related macular degeneration, or AMD. AMD damages the macula, a small part of the eye's light-sensitive retina, the layer of tissue that sends vision signals to the brain. Macular degeneration is characterized by deposits known as drusen that develop in the macula, although the reason these deposits accumulate is not known. There are two ways to lose vision as a result of macular degeneration. Both occur during the early stage of the disorder. December 2003. Higher levels of good dietary fat, including fish and nuts, have been found to diminish the progression of age-related ular degeneration (AMD), and bad fat, such as processed baked goods, increase the progression to the advanced stages of the disease that is associated with vision loss.

New Insights For Macular Degeneration "At the present time, it is not known what causes age-related macular degeneration (AMD) and more importantly, what can be done to prevent it," relates Discovery Fund scientist M.Cristina Kenney, M.D., Ph.D. "What is known is that there are a number of risk factors that increase a person's chance of getting AMD." The macula is the point of central vision on the retina needed for reading, driving, identifying faces, watching TV, and most other routine activities. AMD destroys the sharp central vision required for reading, driving and recognizing faces. Vision blurs and dims until only a ring of peripheral sight remains. At present 10 million Americans show signs of the disease. As many as 20% of people over age 60 develop AMD. Over age 75, the risk jumps dramatically to 40%. When the "baby-boom" generation reaches this milestone, we will be faced with an epidemic of perhaps 21 million Americans with vision loss from AMD. With funding by the Dr. Henry and Lilian Nesburn Macular Degeneration Program and the Henry L. Guenther Foundation, researchers in the laboratories at the University of California, Irvine are looking into both the genetic and environmental influences that make a person susceptible to this eye disease.

Extractions: Age related macular degeneration (AMD) is the leading cause of blindness in people over 60 years in the western world and each year the problem gets bigger. About 25% of the over 60s in the UK have some degree of visual loss because of AMD. In AMD central vision is lost making it impossible to appreciate fine detail. How does it happen? Given the magnitude of the burden of AMD on individuals and society as a whole, it is perhaps surprising that more is not known of the causes of the disease and how it develops. What is clear, however, is that the retinal pigment epithelium (RPE) plays a pivotal role. Abnormal waste material builds up beneath and within the RPE and eventually RPE cells die. The rods and cones in the retina depend for their survival upon normal functioning RPE and so this RPE failure leads to progressive loss of vision. To make matters worse, the disease provokes a scarring process at the back of the eye with the formation of new blood vessels. The retina is very intolerant of this scarring and again, rods and cones are lost. Unlike retinitis pigmentosa most cases of AMD are not caused by mutations in one or two genes although it is clear from studies here and elsewhere that there is a significant genetic component to the disease. In other words, the genetic make up of a person alters their risk of getting AMD. Environmental factors are also important. Diet, smoking, exposure to ultraviolet light and many other factors have been raised as potential causes but definitive answers to these important questions are lacking.

Extractions: The MD Simulator is a Windows software program that dynamically shows the visual implications of Macular Degeneration. Usually MD is explained with a static picture showing a simple blind spot somewhere in the field. However, this does not always explain well the problems an MD patient experiences. In the MD Simulator the blind spot is calculated in real-time and includes aspects like blurring, distortion, and intensity reduction. Furthermore the blind spot can be coupled to the gaze direction (by moving the mouse). This results in a better explanation of the vision limitations of an MD patient.

Extractions: most common cause of vision loss in Australia Vision affected by advanced AMD Normal Vision What is AMD? Age-related macular degeneration (AMD) is a degenerative condition affecting the central area of the retina called the macula. The macula is a small area at the back of the eye which is responsible for fine and reading vision. Conditions affecting the macula reduce the central vision, leaving the peripheral vision intact - for example, you could see the outline of a clock but not be able to tell what time it is. It affects both distance and close vision and can make some activities, like reading, difficult or impossible.

Extractions: Looking for the details According to a recent poll, Canadians fear losing their eyesight considerably more than the use of their legs or hearing, yet 70% of those polled know little about the leading cause of blindness - AMD. Few believe they will ever lose their vision, yet over one third of Canadians between the ages of 55 and 74 develop AMD and nearly 40% of Canadians over the age of 75 develop AMD. It is clear that the risk of developing AMD or living with someone who does may be real for everyone. The information contained in this site will give you a better understanding of the disease, what the treatment options are, how to cope with vision loss and where to get help. The goal of this site is to underline the importance of early detection and the need for proper medical care from a qualified eye-care professional.
