(Greek: strabizein > Modern Latin: "to squint"; imperfect focus; eyes deviating inwardly, deviating outwardly, or one eye going to the right and the other eye going to the left)
"Essentially there are two kinds of strabismus:
- When one or both eyes turn inwardly (esotropia, from Greek eso-, "inward" + trope, "turning").
- When one or both eyes turn outwardly (exotropia, from Greek ex-, "out" + trope, "turning").
"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 or blindness) 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 be more active and to become more normal."
"Severe strabismus may require surgery."
