The Cause And Treatment For Amd
Age Related Macular Degeneration, which is short for AMD
, is mostly happen to old people and is mainly caused by the factors of family history, gender, race and age. Studies show that people who are over the age of 60 are at a higher risk of AMD than the relatively younger and the risk will jump sharply when the age are over 75. The disease is not painful because it is a quite slow process, you cannot even notice its coming. However, it is not a good new as the neglect will help the hiding of potential disease, leading to the final break up, such as the loss of vision in both eyes.
AMD aims to destroy sharp central vision which is a great help to clearly reading and watching. The reason that our eyes can see because of the retina which is the light-sensitive tissue located at the back of eyes. The retina instantly coverts lights and images into electrical signals and then sends them to the brain. Macula is located at the center of retina. If the macular is under degeneration, our eyes are losing its activity.
Generally speaking, AMD comes in two types, including dry AMD and wet AMD. Dry AMD is due to the slow break down of light sensitive cells in the macula, leading to the gradual blurring vision. The worse the dry AMD is, the blurrier the eyes are. Actually, at the beginning the symptom is not very obvious that you cannot recognize the disease at all. You vision is slightly blurry and you need more light to read or watch, but it has the same symptom with the normal vision loss that come with age. Therefore, you should go for a check to rule out the possibility of AMD. Wet AMD is due to the growing up of new blood vessels under the retina, which are fragile and often leak blood and fluid. The leaked blood and fluid will push macula out of its initial place. Damage to macula and loss of central vision occur very rapidly and you can notice the symptom at once. So you are recommended to see your doctor as soon as possible to reduce deeper damage. An easy way to estimate the disease at an earlier period is that you look at a straight line. If the line appears wavy, you are more likely to get the disease of wet AMD.
We know age is the key factor for both forms of AMD, and there are other factors that can possibly cause the AMD disease. Lifestyle plays an important part in the chances of developing this potentially devastating disease. Hence, you should maintain a healthy weight, keep a lid on your blood pressure, get rid of smoking, have a healthy diet rich in fish and greens and do regular exercises to lower your risk of developing AMD.
You can also have visionary supplements to delay or avoid the disease. Honocysteine, which seems like having a relationship with heart health, has a great influence on AMD, so there are some homocysteine-lowering supplements to tame AMD. A trail among 5,442 women proves that taking a combination of Vitamin B6, Vitamin B12 and folic acid can reduce the risk of AMD. However, the benefits do not emerge until two years after you began to take the supplements. Still, it is good evidence that Vitamin B6, Vitamin B12 and folic acid are helpful for AMD prevention. Actually though all the elements in visionary supplements are quite small during the research, some professionals suggest that 50mg of Vitamin B6, 100mcg of Vitamin B12 and 400mcg of folic acid is best for daily use.
Except for those above reason, carbohydrates also affect the risk of AMD. It is reported that there is a link between the glycemic index and the risk of AMD. Glycemic index is a scale applied to food which can determine how quickly the carbohydrates are inverted to glucose. White rice, pasta and bread have a higher glycemic index and are prone to experience the rapider rise and drop of glucose, while whole grains have a lower glycemic index which have a less effect on glucose. Furthermore, a recent research indicates that people who consume diets with a higher glycemic index than the average for their gender and age group are at a greater risk of AMD. So give up foods with high glycemic index like white rice, refined sugar, pasta and bread, and try the low glycemic foods like agave syrup.
Lastly, lutein and zeaxanthin are two nutritional elements fighting against AMD. A report tells that an average of 5.8mg lutein and zeaxanthin per day have a 57 percent decreased risk of AMD. If you already suffer from AMD, you can have supplements with 10mg per day for one year and you will miraculously find that your vision is significantly improved. For an AMD patient at his earlier stage, even a 6mg is beneficial.
