Acquired Nystagmus

Cone-Rod Dystrophy and Acquired Dissociated Vertical Nystagmus

“…2 Asymmetric horizontal nystagmus also has been reported in children with cone dystrophy. 3 Acquired nystagmus is usually of neurological or vestibular origins, and occurs in patients with posterior fossa lesions, 4 multiple sclerosis, 5 internuclear ophthalmoplegia, 5,6 brainstem hemorrhage, 6 and toluene addiction. 7 Dissociated nystagmus relates to asymmetry in the amplitude of nystagmus in the two eyes and usually implies the presence of an intracranial pathology.…”

Recording and interpretation of ocular movements: spontaneous and induced nystagmus

“…33 GEN is suggested when the amplitude of the nystagmus is greater than 4° or it is fixed asymmetrically in both directions. 13,34 The most notable difference is the change in the slow-phase velocity in a dark room. The velocity of the slow phase nearly doubles in end-point nystagmus, whereas in GEN there is almost no change.…”

Implication of Vestibular Hair Cell Loss of Planar Polarity for the Canal and Otolith-Dependent Vestibulo-Ocular Reflexes in Celsr1–/– Mice

“…All eye movement recordings were made in the dark using an infrared video system (ETL-200, ISCAN, Burlington MA), recording pupil, and corneal reflection (CR) position ( Beraneck and Cullen, 2007 ; Beraneck and Lambert, 2009 ; Beraneck et al, 2012 ; Beraneck and Idoux, 2012 ). Eye movements were recorded using non-invasive video-oculography ( Stahl et al, 2000 ). The experimental setup, apparatus, and methods of data acquisition were similar to those described previously ( Beraneck et al, 2012 ; Carcaud et al, 2017 ; Idoux et al, 2018 ).…”
