That won't compile. You can only use override when the method is virtual in the base class. And once it's virtual in the base class it's virtual in the n-th child too.
The dry type may set the stage for the less common but more severe wet form in which blood vessels and scar tissue begin to grow abnormally beneath the retina, leading to permanent damage of the macula. The macula is located at the center of the retina, the light-sensitive tissue lining the back of the eye. The retina converts light, or images, into nerve impulses that are carried to the brain via the optic nerve. People with AMD may gradually lose their central vision, which can seriously impact their quality of life.
We all have our blind spots. We're born with them. It's our blind spots that let us see. Our blind spots are somewhere in the center of the retina. They are where the optic nerve goes through the back wall of the eye, carrying light-triggered electrical impulses to the brain, where we do our actual seeing.. There are no rods or cones at the point where the optic nerve goes through the eye, so there is nothing there to see with.
