In younger children, up to 6 or 8
months, inability to coordinate exactly the movements of both eyes while fixing
some object, leads to the appearance of a divergent motion may suggest the
existence of strabismus. If this difference persists after this period, we must
think seriously about the possibility of a squint. It is therefore necessary to
go to the optometrist to establish an adequate therapy.
In fact, the risk posed by the
strabismus is due to the lack of convergence of the eyeballs prevents correct
image fusion, that makes objects look "double" (double vision).
The child reacts by suppressing
ghosting and using only the one that gives the eye normally aligned. The
persistence of this phenomenon leads, ultimately, not to use the visual eye amblyopia
unused. This divergence can be avoided only if corrected in time, covering the
normal eye to force the other to perform its function.
