Description of intervention(s) / exposure
Neurological disorders are the leading cause of disability world-wide. Due to our aging population and population growth, this burden will inevitably increase over time. To add to this burden, our capacity to detect and treat many neurological disorders is hampered not only by gaps in our knowledge but by a lack of appropriate and cost-effective biomarkers to measure and monitor change in function. The study of eye movements is an established and widely used methodology in experimental research, the assessment of eye movements already an integral part of the clinical examination with distinctive eye movements characteristic of almost all neurological conditions. However, eye movements cannot currently be measured with precision outside of the research setting.

This research aims to establish the utility of the BioEye eyetracking application in measuring aberrant function in some of the most common neurological diseases. By measuring simple eye movement parameters in patients with various neurological conditions we will ascertain whether the application can be used to dissociate individuals with a neurological condition from individuals without a neurological condition (specifically, by using smooth pursuit and pupillary light reflex ocular markers). Beyond this study, this may help to determine whether the BioEye applcation can provide a safe and simple measure of change in neurological function over time.

The researchers will test all participants once, within their neurology clinic at the Alfred Hospital using the BioEye application on a (BioEye) smartphone. To measure smooth pursuit eye movements participants will be asked to follow a dot moving in a circle across the screen of the smartphone. To measure the pupillary light reflex, the BioEye application will use the smartphone flash to illuminate the participants eyes for 3 seconds. Testings sessions will take no longer than 5 minutes (including delivery of instructions).

Diagnosis / Prognosis
Comparator / control treatment
Neurologically healthy controls will undergo the same testing procedure as participants with a neurological disorder. Either within the Alfred Hospital or a place of the participant's choosing the researchers will test all participants once, using the BioEye application on a (BioEye) smartphone. To measure smooth pursuit eye movements participants will be asked to follow a dot moving in a circle across the screen of the smartphone. To measure the pupillary light reflex, the BioEye application will use the smartphone flash to illuminate the participants eyes for 3 seconds. Testings sessions will take no longer than 5 minutes (including delivery of instructions).

Efficacy
Statistical methods / analysis
Statistical methods will align with the development of commercially viable algorithms suitable for identifying change in neurological function. These standard methods will variously include score adjustment for extraneous factors, normalisation/standardisation of scores, principal components analyses, regression analyses, and algorithm development.
