N: 1. The first time it was found in a document was in 1680. It comes from the medical Latin, from Greek strabismos, from strabizein, which means “to squint” and from strabos, which means “squinting, squint-eyed” and it is related to strobos which means “a whirling round”. It comes as well from PIE root *streb(h)- “to wind, turn”.
2. A condition in which the visual axes of each eye are not directed simultaneously to the same fixation point.
3. 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.
4. 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.
5. strabismus: term recommended by the Medical Signs and Symptoms Committee (Canada).
