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.
The retina is the photo receptive sensory layer of the back of the eye, where the optics of the eye focuses an image of what is in front of the eye. The optic nerve carries signals from the retina to the brain, which interprets them as visual images.The retina has two types of cells the rods and cones.he innermost light-sensitive membrane covering the back wall of the eyeball; it is continuous with the optic nerve 6 layers of cells that line the back of the eyeball.   â¦ One layer is sensitive to light and is the first step in turning light into vision.    These cells are a part of your brain.
