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.
The key to understanding whether double vision is due to a problem in the eye or in the brain is to see what happens when one eye is closed. If there is double vision when looking with the right or left eye alone, then the cause is ophthalmologicalâsuch as a cataract, a problem of the retina, or another eye disease. On the other hand, when double vision is present with both eyes open, but goes away upon looking with only one eye, the cause may be neurological. This type of double vision occurs because of abnormal eye movements that cause the eyes to become misaligned. When the eyes are not aligned properly, one eye sees an image in one location, while the other eye sees the same image in another location.
