Genetics usually the cause of macular degeneration

Genetics play a big role on those who end up with macular degeneration, an eye disease that leads to vision loss.

Vitreoretinal specialist Dr. Mandi D. Conway with Arizona Retinal Specialists in Sun City West said caucasians have a genetic disposition to macular degeneration. In contrast, Hispanics, Native Americans, African Americans or Asians have a lower risk.

However, diet may play an important role in getting macular degeneration Ms. Conway noted. Based on studies, she said some believe that fatty acids on the liver that metabolize have an affect on the retina.

It is also suggested that the blue light emitted from the sun can be a cause of macular degeneration, therefore, Ms. Conway recommends people always wear sunglasses outdoors to help lower the risk.
