Nystagmus is a type of eye movement characterized by alternating smooth pursuit in one direction and saccadic movement in the other direction. Nystagmus may be physiologic when occurring normally and serving its normal function or pathologic when occurring abnormally. The presence of Nystagmus can be benign, or it can indicate an underlying visual or otorhino-neurological problem.Through more and more sophisticated video oculagraphy, video oculoscophy and electronystagmography is possible to study the main characteristics of saccadi such as: amplitude and frequency.In the end it is possible to face the kind of therapy: pharmacological, optical, pleoptic, orthotic, prismatic and surgical.
