A risk factor is something that increases your likelihood of getting a disease or condition.
It is possible to develop macular degeneration with or without the risk factors listed below. However, the more risk factors you have, the greater your likelihood of developing macular degeneration. If you have a number of risk factors, ask your doctor what you can do to reduce your risk.
Risk Factors Include:
Adult macular degeneration is more common in people over 50, and the risk increases with advancing age.
According to the Third National Health and Nutrition Examination Survey, adult macular degeneration is more common in whites than in other races.
Genetic factors appear to be very common in early-onset types of macular degeneration. Specific genetic causes for adult macular degeneration have not been identified. However, a positive family history may increase risk.
The following factors all increase your risk of macular degeneration:
According to the National Registry of Drug-Induced Ocular Side Effects, taking certain drugs may increase your risk of developing adult macular degeneration. If you are taking any of these drugs, talk with your doctor about your risk of macular degeneration.
These drugs include:
- Aluminum Nicotinate
- Iodide and Iodine Solutions and Compounds
- Iothalamate Meglumine and/or Sodium
- Iothalamic Acid
