Strabismus.
Treatment and management
As with other
binocular vision disorders, the primary therapeutic goal for those with
strabismus is comfortable, single, clear, normal binocular vision at all
distances and directions of gaze.
If minor and
detected early, amblyopia (lazy eye) can often be corrected with enforced
use of an eyepatch on the dominant eye and/or vision therapy. The use
of eyepatches is unlikely to change the angle of strabismus. Advanced
strabismus is usually treated with a combination of eyeglasses or prisms,
vision therapy, and surgery, depending on the underlying reason for the
misalignment. Surgery attempts to align the eyes by shortening, lengthening,
or changing the position of one or more of the extraocular eye muscles,
and is frequently the only way to achieve cosmetic improvement. Glasses
affect the position by changing the person's reaction to focusing. Prisms
change the way light, and therefore images, strike the eye, simulating
a change in the eye position.
Early treatment
of strabismus and/or amblyopia in infancy can reduce the chance of developing
amblyopia and depth perception problems. Eyes that remain misaligned can
still develop visual problems. Although not a cure for strabismus, prism
lenses can also be used to provide some comfort for sufferers and to prevent
double vision from occurring.
In adults with
previously normal alignment, the onset of strabismus usually results in
double vision (diplopia).
Advocates of
the Bates method assert that it can reverse strabismus, however, this
claim is rejected by the vast majority of mainstream eyecare professionals.
