My child’s eyes are looking in different directions
A mouthful to say, this is the best way to refer to misaligned eyes, whether turned in, out, one higher or lower than the other. Using this term means that on formal testing the person is unable to have or keep their 2 eyes looking at the same object. It indicates that they are unable to use the eyes together (binocular vision) or that this is impaired, rather than a temporary misalignment that disappears when the 2 eyes are open (binocular vision is normal).
A “squint” is not only a problem of the eye that turns, but of the whole control system of both eyes. The nerves and muscles that make the eyes turn send an identical signal that makes both eyes move the same amount, and togther. This is why surgery on both eyes is often used to correct the turn – any change in the position of an eye afects the total direction of the 2 eyes as a unit.
