What are the main symptoms of strabismus in children? Strabismus can be chronic or intermittent. In children with chronic strabismus, one eye looks straight ahead while the other eye looks oblique. The strabismic eye may slant inward or outward, or it may slant vertically up and down, meaning that one eye is higher than the other. Three conditions can occur in a chronically strabismic eye: 1. Amblyopic or lazy eye: When a child is chronically strabismic, he will have weakened vision in the eye due to the lack of use of that eye. An eye with weakened vision due to lack of use is called an amblyopic or lazy eye. 2. Weak binocular vision: The ability to see in depth and stereo requires the use of both eyes in parallel, so a child with chronic strabismus will lack depth and stereo vision. 3. Abnormal head position: In order to use both eyes, some children with long-term strabismus will have abnormal neck, head and face tilt and development.
