Common Vision Conditions Affecting Children |

Eye coordination is the ability of both eyes to work together. Each eye sends an individual image to the brain where, through a process called fusion, they are combined into one three-dimensional picture. Good eye coordination allows the eyes to maintain proper alignment. Poor eye coordination results from lack of adequate vision development or improperly developed eye muscle control. Poor coordination can also result from disease or trauma in rare cases. The images seen by each eye must be nearly the same for the brain to properly fuse them. An individual with poor eye coordination usually will exert extra effort to maintain proper alignment of the eyes. In severe cases, the muscles cannot adjust and the individual may experience double vision. In an attempt to avoid double vision, the brain may ignore the image from one of the eyes. Over time, the ignored eye will have decreased visual function. This condition is called amblyopia, or lazy eye. Since a person can often exert an extra effort to overcome poor eye coordination, it can be difficult to detect. Poor eye coordination can be diagnosed with a comprehensive eye examination. It is often treated with a vision therapy program with a high success rate. Some signs and symptoms that may indicate poor eye coordination in children may include:
- Avoidance of near work.
