Current Opinion in Ophthalmology, 1994
Ophthalmologic nystagmus can be congenital and manifest/latent both of whose waveforms, compensatory mechanisms, and treatment are different. Physiologically, latent nystagmus may be reversed at will, whereas nystagmus and head nodding may be simultaneously triggered at will.

Nystagmus is the repetitive to and fro movement of the eyes, which may be physiological or pathological. The movements can be horizontal, vertical, torsional or a combination of these movements. It starts by a slow movement of the eye away from the visual target. The second movement brings the eye back to the visual target.

Epilepsia, 1984
Summary: “Epileptic nystagmus” unaccompanied by other ictal phenomena is rare. We report four new cases confirmed by ictal EEG and video or cine recording in which nystagmus was a prominent and sometimes the only clinical manifestation of the seizures.

Positional nystagmus may be persistent or transitory. Of the persistent forms, type I refers to nystagmus changing direction in different head positions and type II to nystagmus beating in a single direction. Both types may denote either peripheral or central abnormality.

Hereditary nystagm occurs in latent and manifest form. It can be occur in isolation or together with certain hereditary alterations of the eye or of the central nervous system. The objection to a sharp separation of isolated (extraocular) and ocular hereditary nystagm is that no causal relationship between hereditary bulbar alterations and nystagm need

Alternating nystagmus is a spontaneous nystagmus which changes in direction without any external influence. In the literature this phenomenon has so far been described in 90 cases; in 12 of these, the nystagmus had a congenital origin. In contradistinction to the congenital type, the acquired type of alternating nystagmus is in most cases caused by a ...

Epilepsia, 1971
Most authoritative reviews of nystagmus fail to mention epilepsy as a possible cause. Thirteen reports in the French and Italian literature describe 15 patients in whom attacks of epileptic nystagmus were a remarkable but insignificant part of a clinical picture consisting of regularly recurring minor and major seizures and in some cases gross ...

Optokinetic nystagmus (OKN), one of the phenomena examined in order to analyse balance and sight disturbances, is manifest in two types: The cortical and the subcortical OKN. Their main distinction is in the velocities. They are also transmitted via different nervous pathways.

Current Treatment Options in Neurology, 1999
Patients with acquired forms of nystagmus may suffer from oscillopsia and blurred vision; abolishing or reducing nystagmus ameliorates these symptoms. Ideally, treatment of nystagmus should be directed against the pathophysiologic mechanism responsible.
