Neurological Disorders and Visual Disturbances
Neurological disorders such as stroke, brain tumors and multiple sclerosis can cause visual disturbances. Although other conditions such as astigmatism, cataracts and glaucoma can also cause visual deficits, neurological disorders may cause more profound effects on vision.
Loss of vision can be the result of a stroke as well as a symptom of a stroke. In addition, not only can the vision be impaired as a result of a stroke, the anatomy of the eye may deviate as well. This can lead to drooping of the eye, which is also known as ptosis. Blockages of the blood vessels supplying the optic nerve, brain, or the retina are a common cause of stroke-related vision loss.
The type and severity of vision loss from a stroke depends upon the location of the infarct, as well as the severity. Double vision can also occur as the result of a stroke due to nerve impairment that controls eye movements.
Often, one of the first symptoms of multiple sclerosis is a visual problem, and almost all people who have multiple sclerosis will experience visual deficits at some point in their lives. Since the eyes do not work together correctly in those with multiple sclerosis, it is quite common for these individuals to experience double vision.
Other problems with vision in those suffering from multiple sclerosis include vision that seems to shake. This makes it difficult for patients to watch television or read. Losing vision unilaterally can be caused by a condition known as optic neuritis, also a common finding in those with multiple sclerosis.
