Retinoblastoma

          

          The retina is a lining on the inside of the eye.  The nerve tissue senses light coming through the eye and sends it to the brain and turns it into an image.  Retinoblastoma is a cancer of the eye that starts in the retina.  It is a genetic mutation that causes the bad cells to grow and multiply while the good cells die.  It occurs most common in children and very rarely occurs in adults.  It can occur in one or both eyes.

          Retinoblastoma appears as a white spot in the eye when light hits the area.  Other symptoms include swelling and redness of the eye, poor vision, or crossed eyes.  Having retinoblastoma once increases your chances of it reoccuring.  If the tumor continues to grow it can cause permanent blindness in the affected eye.
