Teaching video neuroimages: see-saw nystagmus.
A 43-year-old woman experienced a worsening of her usual headache. As a right hemifacial hypoesthesia had appeared, the patient underwent a brain MRI that revealed a giant cavernoma localized at the left meso-diencephalic region (figure, A and B). After the operation, an involuntary ocular oscillation known as see-saw nystagmus developed (video on the Neurology® Web site at www.neurology.org). ...
متن کاملSee-saw nystagmus.
See-saw nystagmus is a rare ocular abnormality, only 15 cases having been recorded to date (Maddox, 1914; Rucker, 1946; Larsen, 1957; Jensen, 1959; Smith and Mark, 1959; Mark, Smith, and Kjellberg, 1960; Lourie, 1963; Schurr, 1963; Kinder and Howard, 1963; Slatt and Nykiel, 1964; and Daroff, 1965).

متن کاملSee-saw nystagmus.
See-saw ocular movements are described in two patients, one having obstructive hydrocephalus and the other a thalamic infarct. Electro-oculographic studies demonstrated that the eye movements in patient 1 moved in and out of phase at irregular intervals, in both a horizontal and a vertical direction. The disconjugate eye movements were exaggerated in bright light and less evident during fixatio...
متن کاملTeaching Video NeuroImages: periodic alternating nystagmus evident only in darkness.
An 81-year-old man with retinitis pigmentosa had severe, slowly progressive visual loss that began at age 20. Intermittent nystagmus was observed for 1 decade. Examination revealed severe retinal atrophy and periodic alternating nystagmus (PAN) that occurred only in darkness (video on the Neurology® Web site at www.neurology.org). PAN refers to horizontal nystagmus that periodically reverses di...
متن کاملThe sub-clinical see-saw nystagmus embedded in infantile nystagmus
A transient, decompensated vertical phoria in an individual with infantile nystagmus syndrome (INS) resulted in two images that oscillated vertically-a diplopic oscillopsia. Ocular motor studies during the vertical oscillopsia recreated by vertical prisms, led to the identification of a sub-clinical see-saw nystagmus (SSN), present under the prism-induced diplopic condition. Retrospective analy...
