Strabismus |
Strabismus is a problem caused by one or more
improperly functioning eye muscles, resulting
in a misalignment of the eyes. One eye, or
sometimes both, may turn in (crossed eyes),
turn out (wall eyes), turn up or turn down.
Sometimes more than one of the turns is
present.

Strabismus must be detected early in children because they are so adaptable. If a child
sees double, his or her brain quickly learns to suppress or block out one of the images to
maintain single vision. In a very short time, the brain permanently suppresses vision
from the turned eye, causing amblyopia.
Children may also develop a head tilt or turn to compensate for the problem and
eliminate the double image. Unlike children, adults with a newly acquired strabismus
problem typically see double.
Causes
There are many causes of strabismus. It can be inherited, or it may be caused by trauma,
certain diseases, and sometimes eye surgery. Strabismus cannot be outgrown, not will it
improve by itself. Treatment to straighten the eyes is required. The types of treatments
may be used alone or in combination, depending on the type of strabismus and its cause.
Treatment
Glasses are commonly prescribed to improve focusing and redirect the line of sight,
enabling the eyes to straighten. Medication in the form of eye drops or ointment may be
used, with or without glasses. Injected medication may be used to selectively weaken an
overactive eye muscle.
Surgery may be performed on eye muscles to straighten the eyes if non-surgical means
are unsuccessful. Eye exercise, a limited form of treatment, may be recommended either
before or after surgery to teach proper eye coordination.
