Strabismus – Definition
In strabismus, one or both of the eyes turn in, out, up, or down. It usually occurs in children but may occur in adults. Permanent vision loss may result if strabismus is not detected and treated in a timely manner.
There are two types:
- Constant strabismus — the eye turns all the time
- Intermittent strabismus — the eye turns only some of the time, like in times of stress, illness, concentration, or when tired
