Macular degeneration is one of the most common eye diseases among elderly people. When people are at their 40′s or 50′s, their center vision, which has the task of seeing detailed information, such as reading or playing cards, will begin to diminish. If macular degeneration is not treated early and properly, the center vision will continue to lose, so the best way for people with macular degeneration is to seek the way to preserve their remaining vision.

You may wonder to know what causes macular degeneration. Macular degeneration can be caused by the following factors: First, it may be caused by weakened macula, which is in the center of the retina. Second, the thinning of the cells which contain the macula can also lead to macular degeneration. Third, the bleeding due to blood vessels bursting and leaking under the macula can also cause macular degeneration. Fourth, the macula is weakened and deteriorated itself gradually, which will contribute to macular degeneration. For people with macular degeneration, their center vision is weakened, but their peripheral vision can not be altered, so luckily they will have some vision left.

How people can be diagnosed of macular degeneration? What symptoms macular degeneration has? The most common symptom is people can not see clearly when they are reading. For people with different type of macular degeneration, the vision loss will be different. For most people, they will have part of their vision loss, and can see shadows with a blurry vision while reading.

The other symptom for macular degeneration is the straight lines will seem to be wavy, or people can not see the entire line with parts of lines missing. To diagnose this symptom, eye doctor will give people a test by Amsler Grid Test. From the test, eye doctor can test if people can see straight lines on a grid of horizontal and vertical lines, or see wavy lines.

People with macular degeneration will have low vision in terms of colors. So they have to take color test to check if they can distinguish different dark and dark tones, together with light and light shades. The color distinguish ability is determined by the cone cells in the retina, and from the test, the eye doctor can judge if the cone cells is impaired.

As macular degeneration will also affect our ability to see clearly while driving, so the eye doctor will also give us acuity test to see how well we can see at different vision lengths and under different lights, so in this way, he will measure their central vision loss.

Thanks to the fast development of eye technology that people can have some treatments to alleviate from macular degeneration in order to restore more vision left. And they can also wear special eye glasses to see clearly and save their remaining vision.

Macular Degeneration | Nutritional Supplements for Macular Degeneration

The diagnosis of macular degeneration is becoming increasingly more common due to patient awareness, physician access, groundbreaking improvements in treatment, and the relentless graying of the population exponentially increases the percentage of the population at risk for this condition. Thus, macular degeneration is a formidable challenge to patients, their doctors, and our society as the costs for delivering state-of-the-art care increase.

Macular degeneration, also called age-related macular degeneration (AMD or ARMD) or the now discarded term senile macular degeneration (SMD), describes a variety of pathologic but extremely common conditions that affect the macula (a portion of the retina of the eye) and, therefore, central vision. Central vision is what you see directly in front of you rather than what you see at the side (or periphery) of your vision.

Macular degeneration is caused when part of the retina deteriorates.

The retina is the interior layer of the eye consisting of the receptors and nerves that collect and transmit light signals from the eye into the optic nerve, then to the brain for interpretation as our sense of vision. The macula is the central portion of the retina and is responsible for detailed vision and color vision, the vision we use to read, thread a needle, sign a check, or recognize faces. The macula is a highly specialized part of the nervous system and the eye in which the photoreceptors that react to light stimulus and the neurons that interpret and transmit these signals are precisely organized and densely compacted. It is the macula that allows humans to see 20/20, or an eagle to spot a small rodent on the ground hundreds of feet below.

Nutritional Supplements:

Zinc can, at high doses, cause anemia in some patients as well as exacerbate the symptoms associated with Alzheimer’s. As will be demonstrated later in this chapter, it may be prudent to cut back on the amount of Zinc from the amount used in the controlled study.

Beta-carotene is a substance made from plants that the body can convert into Vitamin A. It also acts as an antioxidant, an immune system booster, helps cells reproduce normally, protects the photoreceptors against free radicals, and enhances night vision. Other members of the carotene family are beta-carotene’s cousins, zeaxanthin, lutein, and lycopene. However, unlike beta-carotene, most of these nutrients do not convert to significant amounts of Vitamin A.

Vitamin C is a water-soluble vitamin that functions as a powerful antioxidant. It is critical to make collagen, the glue that strengthens many parts of the body, such as blood vessels. Vitamin C also plays an important role in wound healing. This vitamin also aids in the formation of liver bile and helps to fight viruses and detoxify alcohol and other toxic substances.

Vitamin E is a powerful antioxidant that protects cell membranes and other fat-soluble parts of the body. In addition to Vitamin E’s benefit for the eyes, two studies published in the New England Journal of Medicine show that both men and women who supplement with at least 100 IU of vitamin E per day for at least two years have a 37-41% drop in the risk of heart disease

Lutein (loo-teen) is a carotenoid found in vegetables and fruits. Lutein acts as an antioxidant, protecting cells against the damaging effects of free radicals. Chances are you’re not getting the lutein you need because most Americans simply don’t eat enough vegetables rich in lutein. A recent survey of eye doctors indicated that 91% believe that lutein promotes eye health and can be beneficial in treating AMD. A recent study sponsored by the National Institutes of Health found that people who ate the highest amounts of leafy green vegetables like kale, collard greens, and spinach had a 57% lower risk of developing AMD than those who ate these foods the least. In an AMD study published in the Journal of the American Optometric Association, it was shown that a diet rich in spinach may help stop AMD and even reverse some of the effects of the disease.

Find powerful herbal remedies Eye Health Care.

Taurine is an amino acid found naturally in egg whites, meat, fish, and milk. High concentrations are found in the heart muscle, white blood cells, skeletal muscle, and central nervous system. In the retina there are two binding proteins specific to taurine. Intracellular concentrations are higher in the retina than in any other region derived from the central nervous system.

The other method of treatment involves Laser Surgery in which a physician uses a laser to target the specific blood vessels that are problematic and causing trauma to the macula. However, it should be noted, that many patients will not qualify for laser treatment, and more importantly, the laser treatment is invasive and can and often does lead to permanent scarring in the area of use, which causes a permanent loss of vision in that particular region. There are nutritional supplements that may aid in limiting the damage to the macula.  These should be used in conjunction with Anti-VEGF treatments not as a alternative.

What Is Age-related Macular Degeneration?

Article by Gabriel Adams

Age-related macular degeneration refers to the deterioration of the tiny central portion of the retina, called the macula. It is the leading cause of severe loss of vision in people who are over the age of sixty.

The macula, a small eraser-sized portion of the retina, is the critical area of the eye. It comprises of a network of photoreceptors that enable you to do anything that requires precise and focused vision including reading, sewing, driving or watching television. The area of the eye surrounding the macula has a far lesser amount of photoreceptors and produces a much poorer image resolution. When macular degeneration occurs, this surrounding area continues to process images. However, these images are blurry and distorted and nothing like the crisp central images produced by macula.

Symptoms of Age-Related Macular Degeneration

Age-related macular degeneration typically does not have any symptoms in the early stages and often goes unrecognized until it progresses to the advanced stage and both eyes are affected. Distortion of straight lines as well as distortion of center of vision with the appearance of dark or white blurry areas is normally the first recognizable signs of macular degeneration. This may progress to changed or diminished color perception and to the gradual loss of central vision.

Causes of Age-Related Macular Degeneration

Studies have failed to turn up any conclusive proof as to the causes of macular degeneration, but age and environmental factors appear to be two of the strongest contributory causes. The likelihood of developing macular degeneration appears to increase with age. Though macular degeneration occurs in all races, it is more common in white people.Macular degeneration also appears to run in families, indicating that genetic factors also play a significant role in the onset of macular degeneration.

Some of the other causes of macular degeneration include:

High blood pressureHigh blood cholesterol levelHigh intake of saturated fatVascular diseaseSmokingOver- exposure to sunlight

The dry form of macular degeneration, in which tiny yellow deposits develop beneath the macula, is more common and indicates that there is a thinning and degeneration of the nerve tissue.

In the neovascular or wet form, abnormal blood vessels, which grow beneath the macula leak blood and fluid under and onto the retina causing the retinal cells to die and resulting in blank spots in the individual’s field of vision. It is important to have regular consultations with the doctor if any of these external symptoms are present.

Age-Related Macular Degeneration Treatment

There is no absolute cure for age-related macular degeneration, but there are several treatment options available. Some of these include:

Laser therapy – the actively growing abnormal cells that are present during macular degeneration can be destroyed by high-energy laser light.

Vitamin supplements – Some patients suffering from intermediate to advanced dry, age-related macular degeneration showed signs of improvement after being administered beta-carotenes, Vitamins E, C, copper and zinc.

Photodynamic laser therapy – This two-step treatment, involves injecting the patient with a light-sensitive drug that is absorbed by the abnormal blood vessel. When a cold laser light is shone into the eye, the drug gets activated and destroys the abnormal blood vessels.

Retinal translocation – This surgical procedure destroys the abnormal blood vessels that lie directly beneath the central portion of the macula, making it impossible to use a laser.

Macular Degeneration: Causes and Symptoms

Posted on by

Macular degeneration is one of the most frequent causes of impaired vision in the UK. This painless eye condition is common among people above the age of 50. According to a report published by National Health Service (NHS) in 2008, approximately 30% of individuals above the age of 75 were suffering from the preliminary stage of macular degeneration and 7% had crossed to the advanced stages. According to one estimate, more than 239,000 people will be affected by age-related macular degeneration by 2011.

What is Macular Degeneration?

Dry macular degeneration is an eye condition that leads to the loss of vision from the centre of the retina, which we use to view fine detail. It means that a person suffering from severe macular degeneration may not be able to read, write or drive. To perform all these activities, we focus our vision through the central portion of the retina, which is called the macula.

This is what enables us to focus on and view subjects that are directly in front of our eyes. The degeneration of the macula does not affect peripheral vision or side vision as severely.

Wet macular degeneration is caused by abnormal blood vessels growing which then leak. This can force the retina to lift away from the eye wall, which then can cause swelling and affect the person’s eyesight. A common symptom for a sufferer of wet AMD is to see straight lines appearing wavy. This needs a trip to the doctor immediately as eyesight lost through wet AMD cannot be retrieved.

Causes of Macular Degeneration

Macular degeneration commonly affects people above 50 years of age. Different health conditions lead to different forms of macular degeneration.

As a person grows older, wear and tear affects the body, especially if the owner has a poor diet of high cholesterol combined with smoking and high blood pressure. Physical changes may occur in the central retinal tissue, the macular, and the rods and cones (or photoreceptors) begin to break down, resulting in deteriorating eyesight. As this worsens, central vision becomes hazy or blurred. This is called dry macular degeneration.

Wet macular degeneration starts with new blood vessels growing in the retina. The new blood vessels can leak blood, causing the retina to lift away from the eye wall and in turn severely damaging the person’s vision. Eyesight destroyed in this way cannot be repaired.

Macular degeneration is a rare phenomenon at a lower age. In younger people, this problem can surface due to some physical defects existing since birth. Inherited genetic disorders can also lead to macular degeneration among younger people.

Macular Degeneration: Major Symptoms

Similar to diabetic retinopathy, macular degeneration starts showing measurable symptoms at a very advanced stage. The two major symptoms of this visual defect are:

Loss of ability to judge the fine details of an object or image.
Loss of ability to understand contrast variation.

Specific symptoms of dry macular degeneration are hazy vision, the inability to identify faces, need for brighter light when reading and difficulty in reading the newspaper. Wet macular degeneration patients will experience more evident symptoms, such as major visual distortion and blind spots.

There are several vision correction methods available to control wet macular degeneration. For dry AMD, control is usually effected by changing to a healthier diet and lifestyle, such as cutting out smoking and reducing fat intake. To detect macular degeneration at an early stage, consult an eye doctor immediately if experiencing changes in eyesight.

For more information on macular degeneration treatment, browse the internet for specialist eye hospitals. Their websites can provide detailed information on the symptoms and treatment available. Look for a specialist provider of ophthalmic services. Make sure they focus on personalised treatment tailored to each of their patients as you’ll want to ensure the best possible results in an environment where you can feel relaxed and well cared for. They should also be using advanced technologies and have leading ophthalmic surgeons on their staff.

That damage involving irregular tissue inhibits increase involving more recent ones. While a scar tissue unquestionably sorts to the retina bringing about loss of imaginative and prescient vision through that region, this must be sacrificed for greater nutritious attention vision from the leftover healthier locations. Antioxidant lack may be recognized to bring on macular weakening. To avoid this specific, clients are proposed to take vitamin supplements with antioxidants that can help hinder release of volatile o2 or maybe free of charge radicals that will cause harm to this retina. Insufficient Vitamins D, Vitamin e antioxidant in addition to beta-carotene by using zinc is known to often be in connection with macular weakening as well. People will need to bring products of those regarding reducing signs. Smokers using macular degeneration are advised to consider modest doses of Nutritional Any at the same time. Additional prescription drugs that can help effortlessly incorporate anecortave acetate or even Retaane, which usually targets on stopping unusual body container development.

macular degeneration devices dcan provide the solution that low vision patients are looking for. They can include specialized eye glasses, computer programs and other technologies that help to maximize the existing vision of those living with macular degeneration symptoms.

This degenerative visual condition usually affects the elderly, although some patients are genetically disposed to it as well. The macula, located in the central portion of the retina, is where detail vision is located. When the macula changes, resulting in bleeding, weaknesses or wasting, degeneration of the macula is the resulting medical condition. It often leaves patients with reduced central vision, and thus often means a reduction in the types of activities that rely on that type of specific detail vision, such as reading or driving.

Thus, patients with this type of visual degeneration are on the lookout for macular generation devices that will improve their existing vision. Low vision can sometimes be improved by using these aids, and can sometimes make possible the activities everyone appreciates, like reading and playing cards.

Bifocal reading glasses can offer an easy solution to reduced vision. Simple to use, you wear the glasses and can change your field of vision by looking through a different part of the lens. Thus, you can see items both far away and close up, and you get to choose the vision length depending on your immediate viewing needs by using bifocal reading glasses.

Eye glass lenses can also be outfitted with miniature telescopes as well. Functioning a bit like the bifocal, the telescopes can be placed either on top of or behind the eye glass lens, and the patient can look through the regular lens to get the benefits of the eye glass prescription. The other choice is to look through the telescopic lens when you need ultra magnification in order to do detail type work such as reading or sewing.

For those wishing to use the computer, there are special monitors which will magnify the font size, making it easier for low vision users to work on the computer. There are also software macular degeneration devices that will take sound and convert it to text, so that you can speak into the computer’s microphone and that sound will result in text on the screen. Other programs take text and turn it into braille documents, so that those with no vision can still participate in an online setting.

Other macular degeneration devices that patients sometimes find effective are closed circuit televisions. You take a book, open it, and then place it under a camera, which then projects the image in a larger font and shows it on the television screen, making it bigger and thus easier to read.

Whether you want to read or use the computer, there are macular degeneration devices that are suited to many specific visual tasks that you might want to explore if you have low vision.

Macular Degeneration Risk Factors

Posted on by

Article by Barry Wheeler

Macular Degeneration is one of the leading causes of blindness in people aged 65 or over. Also called age-related macular degeneration, vision loss occurs when the macula (or the center part of the eye located in the retina) degenerates. This degeneration can be caused by abnormal blood vessel growth and leakage – referred to as wet macular degeneration, or from the build-up of drusen – referred to as dry macular degeneration.

No single person is immune to macular degeneration, but there are some risk factors associated with this eye disease that makes it more likely for an individual to be diagnosed with macular degeneration than others.

There are many risk factors for macular degeneration including:

1. Smoking – there have been some indications that smoking may actually cause macular degeneration;

2. Aging – this is the largest factor contributing to macular degeneration, with 25% of people between the ages of 65 – 74 having the disease. This increases to approximately 33% over the age of 75;

3. Family history – some studies have shown genetic links to macular degeneration;

4. Obesity – people who are overweight are more likely to be diagnosed with severe forms of macular degeneration;

5. High Blood Pressure – as wet macular degeneration is caused when abnormal blood vessels grow and leak behind the macula, high blood pressure may contribute to the onset of this form of the eye disease;

6. Gender – Females tend to be at a higher risk of being diagnosed with macular degeneration than males;

7. Diet – the lack of some key nutrients and antioxidants may be responsible for increasing the effects aging and result in the development of macular degeneration;

8. Sun – Exposure to the sun has been shown to speed the development of macular degeneration

It is important for individuals to asses their own risks associated with macular degeneration. It is also important to have regular eye examinations, especially if there is an increased risk associated with macular degeneration.

Detecting Early Macular Degeneration

Having Regular Eye Examinations is Key to detecting early macular degeneration

Living with low vision is a concern for many, especially those age fifty and over. One of the types of eye vision problems often associated with people in this age range is age related macular degeneration. A degenerative condition of the macula, which is located at the back of the retina in the eye, age related macular degeneration can leave the patient with low vision suitable for reading, driving and other close-up work where detail vision is required.

Your ophthalmologist is your best resource for detecting early macular degeneration. He or she can then offer you preferred macular degeneration treatment options, as well as a full range of eye glasses for macular degeneration, low vision magnifiers, and other aids to help you see better and live a full and active life.

What Procedures Will My Doctor Use for Detecting Early Macular Degeneration?

The first step your physician will take is to ask you if you are experiencing any symptoms associated with macular degeneration. Symptoms can include blurry vision in the central vision field or portions of the vision that are missing, as well as straight lines appearing wavy, an inability to detect color variations between two dark or two light colors, and a long recovery time after you have been out in bright light.

When detecting age related macular degeneration, your doctor will also want to determine how at risk you are for developing age related macular degeneration. Age is a factor; most people with macular degeneration are age fifty and over, although on occasion it will affect children. Those with a family history of the disease are also at a greater risk for developing it as well. Some individuals have a gene that puts them at risk. People who are obese, eat a high fat diet and suffer from high blood pressure stand a greater chance of developing macular degeneration, as do Caucasians.

What vision aids are available?

After detecting early macular degeneration, your physician will provide you with the best options for treatment. They could include the use of low vision magnifiers, as well as specialized eye glasses for macular degeneration.Magnifiers can be as simple as a hand-held device all the way up to lenses that clip over your glasses, so that you can use them for detail vision when needed, and then flip them out of the way when you do not need them. Specialized eye glasses with tiny microscopes allow you to have a very magnified central vision area, yet they are placed on your regular prescription glasses, so that you can look under the microscopes when you want to see through the other lenses, working in much the same way as bifocal lenses do. Your physician can determine if you are showing signs of early macular degeneration and provide you with the best treatment options and vision aids.
