Causes eye damage


You are having trouble HAS central blurred vision? To make matters worse, a straight line looks crooked crooked and not long after that, you begin to realize you are only depends on the visual side.
You might think it a sign points are old and need new glasses. However, more bad news, it is a symptom of macular symptoms of eye damage due to aging (AMD). Although it did not attack anyone, what is more frightening problem is no cure for AMD.
There are two factors that cause AMD, the factors can be controlled and the factors that can not be controlled. Factors that can not be controlled is genetics and aging factors can be controlled while involving smoking, diet is not balanced as well as obesity and exercise. Smoking is very often associated with various health complications. The study found that smokers have a risk of AMD by four times compared to those who do not smoke. Even AMD cases detected between two to three times more in smokers. In short, the more smoke the greater the risk of AMD. Eye Surgeon, Dr Ahmad Fauzi Md. Sharif, said that AMD is a disease generally associated with aging. It destroys the middle points of view and your view is not as sharp lead first. The middle points of view needed to enable us to see objects clearly. Among the daily tasks that require central vision the eye is reading and driving. However, most people do not realize they are dealing with AMD. This is because AMD does not cause any pain. In fact, in some cases it happens so slowly you think AMD is part of the compulsory old age. However, according to a former lecturer of the University Malaya Medical Centre (UMMC), there are also cases where AMD occurs rapidly and causes the central vision two affected eyes. "AMD typically occurs at age 50 and over. Although it is not a factor that can cause blindness, but it affects the quality of life. "At one time, AMD is considered diseases of the west, but a recent study released in May revealed the Asians also tend to attack AMD. "The study across five Asian countries namely Japan, China , South Korea, India and Singapore Asia confirm the frequency of dealing with the early stages of AMD was 6.8 percent, while end-stage AMD was 0.56 percent compared with 8.8 percent and 12:59 per cent in the west. Most of those who attacked AMD, aged 40 to 79 years, "he said. The UMMC Centre for Eye Research, Assoc Prof Dr Fong Choong Sian, said macular refers in the middle of the retina, and it was kind of the light sensitive tissue located behind the points. Generally the retina rapidly changing light or the image to the 'impulse' or an electrical signal. The retina then sends nerve signals to the brain. In the case of AMD, fragile cell is damaged or no longer work. There are two types of AMD, referred to as AMD, AMD Wet and Dry. Wet AMD occurs when new blood vessels grow behind the retina due to the fragile nature, they bleed easily or scratches that cause visual impairment. Wet AMD occurs quickly, and sometimes as a reaction in the early stages of treatment. In all AMD patients, only 10 percent of the detected only with this problem. Clearly, Prof. Fong, Dry AMD refers to a common condition found in patients with AMD. It happens slowly, until finally the patient lost central vision. "Most people come for treatment after the middle blurred vision, seeing a color it looks gray or discolored. But in both types of AMD, it can affect both eyes even if initially it was detected in one eye only, "he said. In Asia, he said, most patients are detected with AMD is that they are faced with Dry AMD. He said if AMD can be classified at the beginning, intermediate, advanced level non-neovaskular neovaskular and advanced levels. "In the early stages of AMD, the patient lost vision usually start slow and have no symptoms. But there are also cases of early AMD, which has symptoms such as blurred vision, failing to adjust the vision of the dark to the light, and require greater light to read small type.
