strabismus
A condition in which the visual axes
of the eyes are not parallel and the eyes appear to be
looking in different directions. In divergent strabis-
mus, or exotropia, the visual axes diverge. In con-
vergent strabismus or esotropia, the visual axes
converge. The danger with strabismus is that the
brain may come to rely more on input from one eye
than the other, and the part of the brain circuitry that
is connected to the less-favored eye may fail to
develop properly, leading to amblyopia (weakened
vision) in that eye. The classic treatment for mild to
moderate strabismus is to cover the stronger eye
with a patch, forcing the weaker eye to do enough
work to catch up. Atropine eyedrops can also be
effective in correcting moderate lazy eye. Severe stra-
bismus may require surgery. Also known as lazy eye.
