Exodeviations or ,wall eyes, refers to eyes that are not straight. One eye
may appear straight and the other eye is turned outward. This can occur on a
constant or an intermittent basis. The intermittent type which is the most
common form usually begins prior to entering school and may be more evident when
the child is not rested. An exodeviation may not be very evident in early
examination particularly at age four. It is helpful for proper diagnosis and
treatment.
In alternate exodeviations the straight eye alternates from one eye to the
next. This sometimes can appear confusing to the parents since one eye may
appear straight and upon reviewing appears to have turned out.
The treatment consists of a good ocular examination to rule out loss of
vision from lack of use known as amblyopia. Eye surgery is considered if the
deviation becomes large enough that it is interfering with normal binocular
vision. Muscle surgery is generally a very successful operation with very few
risks.
With early diagnosis and treatment most patients with exodeviations are able
to obtain good vision and a good appearance. Some patients can even obtain
normal binocular vision. Early intervention will eliminate reduction of vision
from amblyopia.
