Strabismus, also called “lazy eye” and “crossed eyes,” affects 1 to 5 percent of children younger than 6, wrote UTMB Drs. Sally Robinson and Keith Bly in their Healthy Kids column. With normal vision, both eyes are aimed in the same direction and see the same image. The brain blends the two images into one clear 3-D image. Children with strabismus see an object from a slightly different angle in each eye. Gradually the brain begins to ignore the image from the “crooked” eye to avoid a double image. In time, the child looses depth perception and may even lose vision in the “crooked” eye. Parents should talk to their health care provider if they suspect this condition in a child.
