Infantile nystagmus in adulthood

Abstract

Patients with lifelong infantile nystagmus do not usually experience oscillopsia, the finding is often incidental and the patient is aware of its presence. Typical features include spontaneous nystagmus that can be jerk (with an increasing slow phase velocity waveform) or pendular; gaze-evoked nystagmus laterally; a decrease in nystagmus with convergence/near viewing; reversal of smooth pursuit and optokinetic nystagmus is also sometimes seen
