Macular Degeneration has been associated with many risk factors. We have discussed these before but some risk factors include:
- Age
- Having light coloured eyes
- Being female and long-sighted
- Smoking
- Being overweight
- Lack of green vegetables, Omega 3 and an anti-oxidant called Lutein in the diet
A recent study seemed to link a lack of Vitamin D now to macular degeneration. Vitamin D is a very important vitamin. Historically a lack of Vitamin D caused rickets. Rickets weakens and softens bones and was very prevalent in England in the 1600's. In was not until the 1900's that the association of Vitamin D and rickets was discovered.
Lack of Vitamin D today is associated with lack of outdoor activity. Some exposure to sunlight is needed to manufacture an appropriate amount of it. This does not mean to get hours of sunlight but at least 15 minutes per day. The darker your skin the more you need.
Some foods are rich in Vitamin D, while some milk is fortified with it. Salmon for example has some some Vitamin D but the best and easiest source is the sun. Remember everything in moderation. Don't get sun burnt just 15 minutes per day and preferably if its summer not in the middle of the day.
What is interesting is that lack of Vitamin D seems to be associated with a whole host of things other than just rickets. Lack of Vitamin D seems to be associated with asthma, some cancers, autoimmune diseases, obesity and cardiovascular issues.
Ok so let's get back to the study that seemed to imply that lack of Vitamin D was related with macular degeneration. We have to admit it is a bit far fetched! The study was done on mice!
It showed that mice that were deficient in Vitamin D compared to a group of mice that were not had all sorts of irregularities with their eyes. Does this mean that this study can be extrapolated to human eyes? Probably not at the moment.
For those interested CLICK here for a link to the newspaper article. What is important to know is that Vitamin D today is lacking in many people, while the incidence of asthma, some cancers, autoimmune diseases, obesity and cardiovascular issues are on the increase. Being associated is not necessarily a cause. Medical science proceeds slowly and with caution. What is clear though is that if you can't get the sunlight or you are scared of getting skin cancer from too much sun, then supplementing with a vitamin tablet containing Vitamin D might be the way to go.
On your next blood check get your GP to look for Vitamin D deficiency and get on top of it if it is an issue. If lack of Vitamin D does proved to cause macular degeneration by taking enough Vitamin D will put you ahead later in life.
In the mean time you should also keep getting you macula checked. Make an appointment at The Eye Practice on 9290 1899 or BOOK ONLINE HERE.
