Abstract
Patients with congenital nystagmus may seek to dampen the nystagmus by adopting a compensatory head position which allows them to use the null point. This may be on horizontal side gaze, on up or downgaze or with a head tilt to one shoulder. Nystagmus is invariably dampened by convergence which is why it is less on near vision. Nystagmus may be part of the congenital strabismus syndrome or may be present with normal fusion and without strabismus. This paper does not differentiate between types of nystagmus. It discusses the group of patients whose nystagmus forces them to seek a null point with a face turn to improve their vision.
