Double Or Blurred Vision

Brain cancer can produce double or blurred vision in several different ways. It can cause the overall pressure inside of a patient's skull to increase, which can cause their optic disc to become swollen. The optic disc is the part of the eye where the optic nerve enters the brain from the eye, and vision changes occur when the optic disc swells and compresses the optic nerve. Another way brain cancer can cause blurry or double vision is by the accumulation of cerebrospinal fluid in the brain that places too much pressure on the cranial nerves. One of the cranial nerves is the optic nerve, which can become impaired by excessive pressure from too much fluid. An individual who has blurry or double vision as a result of brain cancer most likely has a tumor in the occipital lobe, brain stem, or cerebellum.
