Can neurological problems cause vision problems?
Nerve problems can affect the nerves of the muscles surrounding the eyeball and those that control the dilation and contraction of the pupil. Such problems can result in symptoms such as double vision, nystagmus, oscillopsia and disorders of the pupils, such as anisocoria.
