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 in the very back of the eye, past the vitreous body. Though it's smaller than a dime, it holds millions of cells that are sensitive to light. The retina takes the light the eye receives and changes it into nerve signals so the brain can understand what the eye is seeing.he part of the sclera in front of the coloured part of the eye is called the cornea. Unlike the rest of the sclera, which is white, the cornea is transparent, or completely clear, which lets light travel through it. The cornea helps the eye focus as light makes its way through it.
