Added 11/11/2010

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.

Added 27/10/2010

AMD, the abbreviation of Age-related Macular Degeneration, is deemed as one of the most horrible eye problems among aged people. However, there are still many other people who run much higher risk. It is found that women are much vulnerable to AMD than men.  

How can this happen? This is firmly linked to the amount of estrogen, a kind of female hormone. When it decreases, the risks for women to get AMD become higher on and on. Therefore, the way to reduce the risk is to intake some estrogen.

This is also reinforced by many studies. These studies have found that women with sufficient amount of estrogen run much lower risk of getting AMD. And the subjects who have also received hormone therapy are also much safer while facing this problem. This can well prove that estrogen can protect eyes and vision in combating the whole oxidizing process. And lack of this hormone can lead to very serious outcomes. In other words, AMD is the result of oxidation, and estrogen is a kind of anti-oxidations for it.

And there is a nice way to avoid AMD- keep a balanced diet. Doing so will help women in maintaining decent amount of this hormone and nutrients.

Nutrients are some of the most important factors that may influence eye health. And some of these substances are really nice antioxidants. They can also offer much better vision protection. For example, lutein and many other special nutrients are really nice alternatives to combat AMD. These special substances can really bring great benefits to aged women. On the whole, these nutrients can be found in many fruits and vegetables. Therefore, it is needed for women intake more of these foods.

Of course, there are still many other vitamins that can also do women a lot of benefits in combating AMD. For example, some of the commonest vitamins, like Vitamin C, E, B, etc., are really effective anti-oxidants for AMD and are beneficial for all people.
