Risk Factors of Macular Degeneration
Macular Degeneration is one of the leading causes of blindness and vision loss across the globe. It usually affects people aged of 65 and above, where a degeneration of a part of the retina occurs. There are many Risk Factors of Macular Degeneration although some people may develop the disease with or without its risk factors. Surprisingly, smoking and obesity are the only avoidable but high risk factors of macular degeneration. Smoking ooubles the risks of acquiring AMD because of harmful ingredients used in the manufacture of cigarettes.
Age and family history are also leading risk factors of macular degeneration. Research shows that more that 25 percent of those aged between 65 and 74 have the disease and 33 percent for those aged 75 and above. The disease is also common in some families and not others because of hereditary factor. Therefore, consider your family history and seek medication early to prevent the disease as you age.
People suffering from high blood pressure are prone to developing the disease. This is largely attributed to the fact that, the eye is a highly functional and highly vascular organ with lots of blood vessels. Blood pressure changes more often in patients and since the veins are very sensitive, any change in pressure affects the eye. In case you suffer from hypertension and cardiovascular diseases, it is wise to seek a doctor for diagnosis and medication. This is very important especially with symptoms such as blurry eyes, cloudy vision or eyes blurred vision. Remember, dry macular can affect one or both eyes. And in the case when only one eye is affected, the overall vision may not appear affected the symptoms may be mild and hard to notice.
As mentioned earlier, obesity is also a leading AMD risk factor but it can be avoided. Being overweight exerts pressure to veins in the eye and in extreme cases; a person may develop severe forms of macular degeneration such as neovascular and geographic AMD. To avoid obesity, it is highly recommended to stay off foods with lots of fat such as potato chips, snack foods, French fries, cookies and cakes. The fats not only expose you to obesity but they also increase your chances of developing wet macular degeneration which is quite complicated.
Patients suffering from wet AMD develop new blood cells under the retina which causes swelling, scar tissue and eye hemorrhage. With Macula oedema, a patient may also notice a hemorrhage eye because it causes accumulation of fluid within the retina at the macular area. At the end point, vascular instability occurs hence, a breakdown of the blood retinal barrier.
Low levels of essential body nutrients also cause AMD. It is therefore important to ensure the body receives enough minerals, antioxidant vitamins including vitamin A, C and E. They play a crucial role in preventing vision loss and scotomas of age related macular generation. In addition, avoid too much exposure to ultra violet rays and if you have to go out in the sun, wear protective sun glasses.
