n.名词 noun

Ophthalmology.
- : a disorder of vision due to a deviation from normal orientation of one or both eyes so that both cannot be directed at the same object at the same time; squint; crossed eyes.

On the other hand, in concomitant strabismus, restriction of movement towards the opposite side not unfrequently develops itself.
Strabismus is present when one eye only is directed to the fixed point, while the visual line of the other eye deviates from it.
Thus it happens frequently in divergent strabismus, when one eye is myopic, the other emmetropic.
For near objects the myopic eye is used without accommodation and therefore also without convergent strabismus of the right.
It may, therefore, be useful for our purpose to cite a few cases of periodic convergent strabismus with emmetropia.
