Brief Summary:
The goal of this study is to develop a comfortable system that uses a wearable eye-tracker similar to eyeglasses to assist people with epilepsy in counting and measuring the severity of seizures. Participants will wear an eye-tracker during a routine EEG.

Condition or disease Intervention/treatment
Epilepsy, Generalized Absence Epilepsy Absence Seizures Seizures Seizure Disorder Diagnostic Test: Eye movement analysis

Detailed Description:
Seizures can be difficult to detect outside of the hospital even with careful observation by a caregiver. EEG is the best method that we have to detect seizures- but it is uncomfortable for long term use outside of the hospital. The goal of this study is to develop a comfortable system that uses a wearable eye-tracker similar to eyeglasses to assist people with epilepsy in counting and measuring the severity of seizures. People participating in this study will have a routine EEG performed while an eye tracker measures eye movements. After the EEG is complete the researchers will compare the eye movements to the EEG to develop a software program that can detect seizures from eye movements.

Group/Cohort Intervention/treatment
Absence Seizures
Participants with absence seizures will have their eye movements compared to the EEG recording.
 Diagnostic Test: Eye movement analysis
Eye movements will be analyzed to identify if seizures are present and compared to the EEG read


Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Eysz algorithm to detect absence seizures [ Time Frame: 1 hour ]
    EEG is burdensome and limited. The current accepted method of counting seizures is observation which fails to identify > 50% of seizures. The goal is to validate the Eysz absence seizure detection algorithm and show significant improvement over current standard of care
