H50: Other strabismus

H50.3: Intermittent heterotropia

Normally, when you look straight ahead, both eyes look straight ahead. Squinting alters the position of one or both eyes. For example, the affected eye can point more to the side or upwards or downwards. You can have a squint from birth. However, it can also be the result of other conditions.

In your case, one eye points more in another direction than the other eye. Squinting remains the same in all viewing directions.

You only squint occasionally.

Squinting can distort the vision with both eyes. Spatial vision may be distorted, for example, or you may have double vision. Squinting can also result in permanent visual impairment.
