Age Related Macular Degeneration
August 5, 2008
Age-Related Macular Degeneration (AMD) is a disease associated with aging and is a common eye disorder which causes deterioration of the macula, which is the central area of the retina, thereby deteriorating the central vision with time. Macular degeneration varies widely in severity and in worse cases it can cause a complete loss of central vision while in most cases in only causes slight distortion. However, AMD cannot lead to total blindness as it does not affect the peripheral vision. This is a disease which leads to a damage of the macula thereby leading to the development of blind spots and blurred or distorted vision which can disrupt daily activities like driving and reading.
Macular degeneration is mostly associated with the process of aging which leads to a breakdown or thinning of the tissues in the macula. This problem can be inherited and can also be occasionally caused by injuries, infections or inflammation. In addition, nutrition, smoking, overweight and sunlight exposure can also lead to this eye problem. AMD usually occurs in two forms: wet and dry. Wet AMD is advanced form of the problem and it occurs when abnormal blood vessels behind the retina start to grow under the macula which in turn leads to a faster damage to the macula.
Wet AMD can be cured through laser photocoagulation which is effective in sealing leaking or bleeding vessels. While this therapy cannot help in restoring back the lost vision, it can help in preventing further loss. It is rightly said that prevention is better than cure and this applies to almost all diseases. By indulging in proper nutrition which consists of diets rich in fruits and vegetables, especially dark leafy green ones, one can prevent this eye problem from occurring. Similarly, avoiding smoking, keeping one’s weight and blood pressure under check and regular exercising can all help in the prevention of macular degeneration.
