Detecting neurological injury and disease with a novel eye-tracking device (Ref: RDFC21/HLS/SER/STUART)


Faculty of Health and Life Sciences

Friday, June 04, 2021 Funded PhD Project (UK Students Only)

About the Project

Examination of eye movements is a central element of a neurological assessment. Clinicians rely upon subjective observation of eye movements, but reliance on clinical experience and judgement can lead to missed impairment or undiagnosed deficits. Technological progression has allowed eye-tracking devices to reduce in size and cost, which now allows clinicians to objectively assess eye movements accurately and quickly. Subtle eye movement metrics such as velocity, latency, gain, duration etc. that cannot be seen upon clinical inspection can be recorded using eye-tracking technology, giving almost immediate evidence of any abnormalities that may be present. Despite the accuracy and objective nature of eye-tracking technology it is not regularly used within clinics to examine for abnormalities in neurological populations, such as mild traumatic brain injury and Parkinson’s disease. Development of novel eye-tracking devices that can detect subtle neurological impairments will allow for improved diagnostic assessments, monitoring and aid with earlier intervention for issues.

This project aims to use, evaluate and inform the application of a novel eye-tracking device (iTremor) for assessment of neurological populations, such as mild traumatic brain injury and Parkinson’s disease.

The PhD candidate will benefit from working within a multidisciplinary team of clinicians (Dr Samuel Stuart, Dr Rosie Morris) and engineers (Dr Alan Godfrey). This is a collaborative project between an industry partner, Head Diagnostics, and Northumbria University, therefore the candidate will also benefit from industry experience.

 

The PhD candidate will;

• Coordinate with partners for use of the iTremor system

• Design and organise data collection in collaboration with relevant professionals

• Investigate the iTremor systems ability to differentiate and examine neurological populations

 

This project is relevant for individuals with clinical backgrounds (e.g. physiotherapist, medic etc.), as well as psychology, neuroscience, engineering/computer science or biomechanics graduates, ideally with experience of eye movement assessments and an interest in neurology.
