Classification of non-nystagmic spontaneous pathological eye movements.
We attempted to classify the well-known spontaneous pathological eye movement (SPEM), to provide a unified nomenclature, to describe its pathophysiology, and to determine its significance in determining a differential diagnosis. Nomenclature was according to the first reporter. These phenomena are easy to confuse with artifact when recording ENGs. A careful analysis which considers history and general neurological findings can identify many of these as true clinical findings which may be as important as nystagmus in the establishing of a clinical diagnosis. Each SPEM, once confirmed, plays a decisive role in the localization of lesions within the central nervous system.
