Strabismus is when the
eyes are not lined up correctly.
More to Know
In strabismus, the brain
may get a blurry image from the eye
that is not lined up correctly. To avoid double vision, the brain ignores the image
from that eye. If strabismus is not corrected, this can lead to "lazy eye" (amblyopia)
with low vision. Strabismus and amblyopia
are closely related and often occur together.
One eye may appear to turn in (called esotropia), out (exotropia), up (hypertropia),
or down (hypotropia). You might hear strabismus called "crossed eyes" (when the eye
turns in) or "walleye" (when the eye turns out).
Strabismus can be constant
or might come and go; it might affect one eye only or switch from one eye to the other.
Those with a family history of strabismus may be at an increased risk for the condition.
Keep in Mind
Treatment depends on the type of strabismus. To improve vision and to line the
eyes up properly, a child may need glasses, an eye patch, or eye drops to treat a
lazy eye. Sometimes, eye exercises are prescribed. Strabismus can cause vision problems
if not treated. If those treatments do not help the eyes line up correctly, surgery
may be recommended.
