Well, yes, generally speaking, strabismus can be caused because of the injury to the head. According to the researches, strabismus is typically caused by injury to the eye orbit. And at the same time, injuries to the brain, such as with a stroke or head injury can lead to strabismus too. So you should take care. And you should know that strabismus may be decided as either constant or intermittent, based on the frequency with which an eye deviates. For the causes, there are also some other factors, such as sickness or stress. Anyway, just be careful about it.
