Abstract:
Eye tracking technique is an examination method to record eye movements and gaze position over time and task,common eye movement parameters include sweep,smooth pursuit,gaze,and visual search.Neurodegenerative diseases such as Alzheimer disease,AD,fronto temporal dementia(FTD),dementia with Lewy bodies(DLB),Parkinson disease,PD,multi-system atrophy(MSA),progressive supranuclear palsy(PSP),motor neuron disease(MND)and corticobasal degeneration(CBD),etc.,have different degrees and manifestations of abnormalities in the above eye movement parameters.For example,there are different degrees of prolonged sweep latency and increased sweep error rate among different diseases.Eye movement tracking technology is of great value in the early identification,diagnosis and auxiliary differential diagnosis of cognitive dysfunction in various neurodegenerative diseases,and is a new method that is non-invasive,convenient,objective and accurate.
