Description of intervention(s) / exposure
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 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.

Outcomes
Primary outcome [1] 330478 0
To assess the level of compliance in wearing glasses for the purpose of measuring eyelid movements with/without relation to seizures in an outpatient setting.
This assessment is done by comparison of the recorded eyelid movement in relation to trial period and also in relation to seizure times as recorded in their seizure diary. Recorded eyelid movements will be assessed at the end of the trial from the downloaded data.
Timepoint [1] 330478 0
The participant wear the glasses during their waking hours when outside of the clinic and record any seizure in their seizure diary for a period of a week.. Data may be assessed during the week to ensure data quality is being maintained. Analysis of compliance shall be done after the participant has completed their part of the study.
Primary outcome [2] 330479 0
To examine the level of acceptance of wearing specialized glasses in an outpatient setting, a questionnaire specific for this study has been developed.
Timepoint [2] 330479 0
Enrolled participants will complete a questionnaire at the end of their week of wearing the glasses. These questionnaires will be compiled and assessed after all participants have completed the study.
Primary outcome [3] 330507 0
To examine any changes in blink characteristics of wearing specialized glasses in an outpatient setting. Characteristics include inter-blink parameters such as blink rate and intra-blink characteristics such as amplitude-velocity ratio, blink total duration and blink eyelid closure duration.
Timepoint [3] 330507 0
The data collected during the measurements in the clinical setting will be compared with the data collected during the week of glasses usage. This analysis shall be done after all study data has been collected.
Secondary outcome [1] 406387 0
To determine whether there are changes to eyelid movements immediately before, during and following non-epileptic seizures, using the non-invasive wearable device (“Eagle Wireless Glasses”), which measures ocular parameters using infrared reflectance oculography.
Timepoint [1] 406387 0
The analysis of ocular parameters shall be done after all study data has been collected.

Statistical methods / analysis
Across 30 participants, cohort compliance measures will also be assessed to determine overall level of compliance. These will also be evaluated with and without reference to their respective seizure events.
Close-ended quantitative questions will be analysed using appropriate statistical measures (mode, median for ordinal scaled and ANOVA, t-test, correlations analysis for interval scaled data). Demographics or open-ended qualitative questions will also be used to perform cross-tabulation with Chi-square analysis or studied independently.

Summary
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.
