It most often occurs because of penetrating head wounds. The frontal and temporal lobes are frequently involved. Of course this type of injury could occur anywhere in the brain. Dysphagia, aphasia, apraxia, dysarthria, paralysis, as well as visual and other problems can occur.
Double vision redirects here. For other uses, see Double vision (disambiguation). Diplopia, commonly known as double vision, is the simultaneous perception of two images of a single object that may be displaced horizontally, vertically, diagonally (i.e., both vertically and horizontally), or rotationally in relation to each other.
Double vision can have many different causes, but it is important to distinguish between double vision seen with one eye alone, as opposed to that seen with both eyes at the same time. In other words, if the double vision disappears when one or the other eye is closed, it is due to a misalignment between the two eyes.
