Recovery nystagmus revisited.
Recovery nystagmus (RN) describes a spontaneous nystagmus with a fast-phase beating toward the ipsilesional ear. The mechanisms underlying RN implicate central vestibular system compensation processes. The presence of RN is significant because it implies that function has returned from the affected peripheral vestibular system. A case is described where RN was recorded. The processes underlying RN are described.
