Common condition in which one eye deviates in
any direction. A squint may be convergent
(with the bad eye turned inward), divergent
(outward), or, in rare cases, vertical. A
convergent squint is also calledcross-eye.
There are two types of squint: paralytic,
arising from disease or damage involving the
extraocular muscles or their nerve supply;
and nonparalytic, which may be inherited or
due to some refractive error within the eye.
Nonparalytic (or concomitant) squint is the
typical condition seen in small children. It
is treated by corrective glasses, exercises
for the eye muscles, or surgery.
