Pendular nystagmus
Description
Acquired pendular nystagmus in multiple sclerosis tends to cause significant oscillopsia (unless the patient is blind), and the vector can be anything, although horizontal is quite common. This patient has more elliptical nystagmus in the right eye (OD); more horizontal and torsional in the left eye (OS), and the nystagmus is higher velocity in the right eye (a dissociated nystagmus, which tends to be stronger in the worse-seeing eye - i.e., the eye with more optic nerve damage).
