Age related Macular Degeneration (ARMD) affects the older populations, as there are a tendency because of it to happen mostly in whites and females. Sometimes, the ARMD can be a side effect some drugs as well as it is hereditary.
There are other factors associated with ARMD, and new evidence linked lifestyle and habits as causes of ARMD that adds about the possible reasons. Some scientists even suggested that over-exposure to sunlight can be a cause for growth and development of ARMD.
Aging
It's reported from the Canadian Medical Association Journal that advanced AMD increases from fewer than 1 percent for all in the 60s and increase to more than 15 percent for individuals who reach their 90s. In the us, ARMD affects over 1.75 million people that year 2004, and likely to increase to almost 3 million by year 2020.
Obesity & Sedentary Lifestyle
A survey in June 2003 in Archives of Ophthalmology says individuals who are overweight face double the risks of developing macular disease than these with normal bodyweight. Those who performed activities rigorously not less than three times weekly will reduce their likelihood of developing advanced ARMD than these who lead a sedentary lifestyle.
Blood pressure levels
Surely we can't dismiss the fact most folks who lead a sedentary lifestyle includes a high risk of besides obesity, but in addition high blood pressure. Hypertension has been said to be a source of ARMD, and the Investigative Ophthalmology and vision Science reported the outcome of an European study to back up this view in September 2003.
Genetic Inheritance
Yes, studies found out that there are several genes that could determine the roll-out of macular disease. Studies of identical and fraternal twins may demonstrate that macular degeneration might be caused by inherited genetics as well as determine how bad it might be.
Smoking
Smoking is considered a reason for a lot of health problems, including macular degeneration. You are able to to be a major ARMD risk factor in fact it is said that smoking is related to 25 percent of ARMD that creates severe vision loss. This became reported within the British Journal of Opthalmology in year 2006.
Lighter Eye Color
Some people theorised that macular degeneration is a lot more popular among people that have lighter eye colors. This might be because macular degeneration might be more profound in Caucasians with ligher skin color and the color of eyes. However, a 2006 report from the British Journal or Opthalmology revealed no relation between lighter skin and eye colors to ARMD. Perhaps there ought to be more studies with better tests solutions to examine whether there's or there's no association between these factors and macular degeneration.
Drug Unwanted side effects
It is said that uncomfortable side effects from some drugs could cause macular degeneration, such as the anti-malarial drug Aralen and anti-psychotic drug Phenothiazine.
There are lots of inconsistencies with regards to the results and findings in the risks factors of macular degeneration. This can be acknowledged with the American Academy of Ophthalmology, and also the only consistency possibly the relationship of aging and smoking to the disease.
