Demyelination of the brain stem, cerebellum, or the ocular motor nerves (cranial nerves III, IV, and VI) can lead to ocular misalignment causing diplopia or double vision. MS should be considered in young patients who have acute or subacute double vision.
Myopia, or near-sightedness, is not caused by MS demyelination.
Presbyopia, or the inability to see close objects due to aging, is not caused by MS demyelination.
Cataract, or a cloudy lens of the eye, is not caused by MS demyelination.
