Brief summary

The purpose of this study is to assess the level of compliance in wearing glasses for the purpose of measuring eyelid movements in relation to seizures in an outpatient setting. This will be achieved by objective measurement of time worn, in relation to temporal proximity of seizure events as well as using a questionnaire to assess the level of acceptance by participants in using the glasses. In addition it will be asses whether changes in eyelid movements occur immediately before, during and/or following NES, using the glasses and whether eyelid movements in NES patients exhibit different characteristics than in previously collected eyelid movement data from people without NES, including people with epilepsy.

Interventions

This is a single-site, prospective, pilot study using glasses (“Eagle Wireless Glasses”), which measures eyelid movements using infrared reflectance oculography. Adult (18 years or older) participants, pre-diagnosed with Non-Epileptic Seizure (NES) admitted or attending The Alfred Hospital meeting the selection criteria will be invited to participate in the study. Enrolled participants will be fitted and asked to wear the Eagle Wireless Glasses whilst doing a standardized vigilance test during

Adult (18 years or older) participants, pre-diagnosed with Non-Epileptic Seizure (NES) admitted or attending The Alfred Hospital meeting the selection criteria will be invited to participate in the study. Enrolled participants will be fitted and asked to wear the Eagle Wireless Glasses whilst doing a standardized vigilance test during a clinical visit. This is a 15 minute test that requires the participant to respond via button press to a shape changing on a monitor in front of them. They will then wear the glasses at home, during waking hours, for the subsequent week and record any seizures in a seizure diary. Ocular parameters will be recorded during wakefulness. A analysis of the times wearing glasses will be made against a number of parameters including total time worn during the week, wearing prior to a seizure, wearing during a seizure and wearing in the 15 minutes after a seizure.
