What is macular degeneration?
user
Well, macular degeneration is a common condition where the cells in the center of the retina (called the macula) lose their ability to receive light.  This loss of visual function, usually due to damage to the blood vessels that supply the retina, leads to blindness in the affected eye(s).  The condition is very common in people over the age of 60.  It’s not treatable and cannot be reversed.

Do you know what damages the blood vessels that supply the retina?
user
Yes, it’s caused by the build up of toxic deposits (called drusen) in the eye, similar to the build up of calcium deposits in your arteries that can lead to hardening of the arteries.  The leading causes of this build up of deposits are smoking, high cholesterol levels, high blood pressure, and diabetes.

Can an ophthalmologist see the drusen?
