“…With the lack of quantifiable objective measures of disease in MND, characteristic eye movement abnormalities could be of great use both diagnostically and in research. Although eye movements are classically spared in MND some patients have been reported with a range of ocular motor disorders including nystagmus, saccadic hypometria [28], slowed saccades [8,33], increased saccadic latencies [25], decreased smooth pursuit gain [3,23,25, 32] and saccadic interruptions of smooth pursuit [20] although these studies were small and often predated the El Escorial criteria. The most comprehensive study to date [37], however, found increased antisaccadic error rates and latencies with relative preservation of reflexive saccades suggesting frontal lobe dysfunction.…”

“…One of the participants with ALS demonstrated impairments in the velocity of his saccades. This type of problem may affect not only ALS patients [Leveille et al 1982], but also DMD patients [Lui et al 2001]. Ashtiani and MacKenzie [2010] previously mentioned this limitation while advocating the development of a text entry technique based on blinking instead of eye movements for the severely motor impaired.…”

“…The advanced stage of P3's disease impacted the movements of his eyes. He has saccades with longer duration and slower velocity, which is a reported symptom for some ALS patients [Leveille et al 1982]. With a dwell-based eye typing technique, this problem can be overcome by increasing the required dwell time.…”

“…Na ELA, os núcleos dos pares III, IV e VI costumam ser histopatologicamente normais (34) , mas em poucos casos pode existir algum grau de oftalmoplegia aparentemente associada ao uso de respirador por longo tempo (37)(38) . Em outros pacientes, a eletro-oculografia (34) consegue revelar dificuldades nos movimentos voluntários sacá-dicos, nos de convergência e perseguição ou alterações do reflexo vestíbulo-ocular, do nistagmo optocinético (38) ou do fenômeno de Bell (39) , indicando lesão nas vias córtico-óculo-motoras e sugerindo distúrbio supranuclear extrapiramidal (40) , ou supratentorial piramidal (41) . O aumento na taxa de erros nos testes neuropsicológicos óculo-motores também tem sido associado a uma disfunção do córtex frontal (42)(43) .…”
