Age-related Macular Degeneration (AMD) is an eye disorder which is responsible only for central vision loss. To learn what causes macular degeneration, let us first understand where does it exactly occur.
This vision blinding disease is caused when the human eye’s macula begins to erode or break down. What is macula? It is located in the center of the retina and contains the largest concentration of light-sensitive cells and cones. The macula in the retina is responsible for human’s central vision and also renders an ability to distinguish fine details. So, eroding or breaking down of the macula is the primary cause of AMD.
Many surveys and researches have proved AMD to be a leading cause of vision loss in people aged 60 or older. However, people with an age of 40 or above are susceptible to AMD.
To be specific in understanding the issue of AMD. It is important to note that AMD is responsible only for the central vision loss and does not cause total blindness. It means, the individual suffering from AMD would lose their central vision, but their peripheral vision would be intact.
Note: Central vision assists you to view straight ahead and peripheral vision is about what you see on the sides when looking straight ahead.
Causes Of AMD
The primary cause of macular degeneration has been its deterioration and inability to operate with age. However, there are conditions that increase the risk of developing the condition.
-
Being over the age of 60
-
Genetics or Family History of macular degeneration. Researches have found around 20 genes that may affect the risk of developing AMD.
-
Smoking, several types of research have shown that excessive smoking doubles the risk of AMD.
-
Being Caucasian, AMD is more common among Caucasians when compared to African-Americans or Latinos/Hispanics.
-
Having cardiovascular disease
-
Being overweight
How to Prevent AMD?
Although there exist some uncontrollable factors such as family history, genetics that drive AMD. Below are some notable prevention ways, which you necessarily must follow to ensure the overall well-being of your eye.
Exercise:
It’s one of the best methods to pump oxygen throughout your body. Exercising pumps the oxygen and increased oxygen is equal to healthy retinas.
Wearing Sunglasses:
UV rays are the most harmful rays that damage the human eye in the worst way possible. Therefore, it is recommended to wear sunglasses to protect your eyes against UV radiations.
Quit Smoking:
If you are a smoker, try quitting it as soon as possible. Trust us it would be one of the huge favor you would do to yourself.
Eye Checkups:
Eyes are a sensitive human organ. Consequently, it’s imperative to get regular eye exams to catch any potential problems before they become irreparable.
Several types of research on Macular Degeneration have proved that a diet rich in vegetables (leafy and dark green) and fruits tend to have a lower incidence of AMD. It is also recommended to consume fish three times a week and avoid saturated fats.
