Eye symptoms are very common with multiple sclerosis (MS). Sometimes the first sign of MS is a problem with vision or movement of the eyes. These are some of the eye problems that can be found in patients with MS.
Optic Neuritis
Optic neuritis often occurs at the onset of multiple sclerosis; people with optic neuritis lose some degree of vision in the affected eye, but for some patients the vision returns over time.
Double Vision
Multiple sclerosis can impact the muscles that control the movements of the eye which can lead to double vision; this condition will usually resolve itself without treatment.
Intranuclear Ophthalmoplegia
Intranuclear ophthalmoplegia is caused by uncontrolled movements in one eye because of a lesion on a specific section of the brain; this can sometimes cause double vision.
Nystagmus
Nystagmus is abnormal horizontal or vertical movements of the eyes and can be either mild or visually disabling.
Ocular Dysmetria
This condition is the constant overshooting of the eyes when attempting to focus on an object; this is caused by a lesion in the cerebellum, the area that controls movement.
Afferent Pupillary Defect
When one pupil does not react to light appropriately, one pupil can often be larger than the other; this can be caused by damage to the optic nerve by optic neuritis or other conditions.
