3.Causes
Doctors don’t know exactly why macular degeneration happens, but your family history plays a part. Your chances of having it go up if you have a parent, sibling, or child with the disease. But your lifestyle matters, too. For example, smokers are twice as likely to have it as people who don’t light up. Other things that make it more likely include being female, being exposed to ultraviolet light, and getting older.
4.Diagnosis
Your eye doctor may put drops in your eyes to dilate (widen) your pupils. This let them use a special device called an ophthalmoscope to look for fatty deposits and other signs of trouble in the back of your retina. If your doctor thinks you have the wet type, they will take a special scan of your eye that can show any problem blood vessels. Yearly eye exams can help your doctor spot early signs before you have any symptoms.
