Detailed recordings of eye movements are an important part of the investigation and diagnosis of nystagmus, which is a condition where the eyes constantly move rather than stay still. Eye movement recording is not available in every eye clinic due to the cost of the eye tracking equipment and the expertise required to interpret the results.
This pilot study aims to compare a low-cost eye tracker (Fove virtual reality (VR) headset) to a currently available eye tracking device (Eyelink 1000+). The aim is to find out whether the low-cost device could provide results that are sufficiently accurate to be useful to support the clinical picture of nystagmus.
The Eyelink 1000+ is an eye tracker already used in clinical practice to support the interpretation of the eye movement and in research studies. The Fove VR headset is commercially available and most used for video gaming, and it already has eye tracking capabilities built into it.
In this pilot study volunteers with nystagmus will be recruited from the eye clinic and from a national nystagmus charity (Nystagmus Network). Volunteers without nystagmus (with stable eye position) will be recruited from eye clinic staff. All volunteers will have their eye movements recorded with both devices.
Firstly, expert clinicians will interpret the recordings from the two devices to see whether the low-cost Fove VR headset can record eye movements with enough accuracy to enable an expert to diagnose the presence of nystagmus and the subtype of nystagmus. Secondly, the results recorded from the two devices will be compared. Thirdly, participant views of the two devices will be compared.
The results of this pilot study will inform an application for a possible future larger trial exploring the use of low-cost eye tracking for the investigation, diagnosis and management of nystagmus and other eye movement disorders in the eye clinic.

You can take part if:
You may not be able to take part if:
• Children (less than 18 years of age) • Participants with nystagmus that is not present in primary position, for example gaze evoked nystagmus or nystagmus that is only present in a secondary or tertiary position of gaze • Unable to give informed consent * Not able to understand written English • Unable to undertake eye movement recordings, during fixation in primary position, with the Eyelink1000+ device and the Fove VR headset • Unable to see the target with both eyes open and with each eye separately (using each device) • Manifest strabismus greater than 10PD
