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.
Doctors want to know whether double vision involves one or both eyes and whether it is constant or comes and goes. They also ask whether the images are side by side or on top of one another and whether double vision tends to occur only when the person is gazing in a particular direction. Doctors ask about any pain, numbness of the forehead or cheek, facial weakness, vertigo, and swallowing or speech problems because these symptoms may indicate a cranial nerve problem.
