Abstract

ABSTRACTNystagmoid eye movements are involuntary eye movements that are not pure forms of nystagmus. Nystagmus, by definition, is involuntary eye movements off of fixation that are initiated by a slow phase. By contrast, nystagmoid movements are often saccades that interrupt fixation or have a fast phase followed by a slow phase. Types of nystagmoid eye movements include saccadic intrusions, such as square wave jerks and ocular flutter/opsoclonus, voluntary nystagmus, superior oblique myokymia, as well as the Heimann-Bielschowsky phenomenon. In addition, sensory intermittent exotropia is a clinical entity that should be on the differential when considering patients with involuntary eye movements, many of whom will also have a history of decreased visual acuity. Other ocular comorbidities in these patients include optic nerve and retinal pathology, as well possible neurological findings such as head trauma or demyelinating disease.
