Current Opinion in Opthalmology, 1998
This report reviews the recent contributions to the field of pathologic nystagmus. The classification and nomenclature of nystagmus with onset in infancy is controversial. Because there are differences in nystagmus forms between patients with idiopathic nystagmus and those with nystagmus associated with afferent sensory defects, a distinction between ...

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.

Current Opinion in Ophthalmology, 1995
Electronystagmographic studies with an attempt to quantify various parameters of congenital nystagmus are interesting although not conclusive clinically. This is due to the spontaneous variability of congenital nystagmus. A qualitative study (position and velocity) may be sufficient for clinical examination and treatment of congenital nystagmus.

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.

Optometry and Vision Science, 1970
ABSTRACT The subject of voluntary nystagmus is presented and defined. A case report of a young female demonstrating this unusual ability is presented. Past descriptions of this condition were studied and the similarities and variations found in this patient are described.

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.

Archives of Neurology & Psychiatry, 1946
Nystagmus is a common sign in diseases of the nervous system, and it is also observed in diseases of the eye and of the inner ear. It may, however, be a normal phenomenon in certain circumstances, or it may be elicited experimentally or as part of the clinical examination.

Acta Ophthalmologica, 1984
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.

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 ...
