This is a rather unique case of primary position nystagmus where we can see the eyes moving elliptically. This patient with MS has the elliptical form of acquired pendular nystagmus. (APN) APN has horizontal, vertical and torsional components, although one component may predominate. If the horizontal and vertical oscillations are in phase, the trajectory of the nystagmus is oblique. If the horizontal and vertical osillary components are out of phase, the trajectory of the nystagmus is elliptical, as in this case. A special case is when horizontal and vertical components are equal but are 90 degrees phase shifted. The trajectory is then circular. Oscillopsia is a prominent symptom with APN, but is seldom a complaint with the congenital form. |
