Study summary

To evaluate the reliability of using the iTremor device to accurately measure Ocular Microtremor (OMT) across a diverse cohort, representative of the US population, with a view to establishing this as a standard measurement tool for OMT.

Read the detailed description

This multisite study intends to evaluate the performance of the iTremor device developed for the measurement of 'Ocular Microtremor' (OMT) - a very high frequency, very small vibration present in the eye. The iTremor is the first non-invasive technique to provide an output of OMT, reported as frequency (Hertz) at the point of care.

The current study is a prospective, observational, multicenter study of the safety and reliability of the iTremor device to obtain an ocular microtremor (OMT) measurement in subjects ≥18 years in a diverse cohort of the US population. By reporting the repeatability of the OMT reading, the study intends to support establishing this as a standard, point of care measurement tool for OMT.

Study population

The study will enroll 120 US subjects total, 18 years of age and older, reflecting the gender, age and racial diversity of the US population. Health status and history will be documented to reflect an all-comers participant group.

Inclusion criteria

  • Adults 18 years of age or older.
  • Normal or corrected to normal bilateral vision.
  • Ability to sit and look forward for periods of at least 5 seconds.
  • Communicate in English with the study team.

Exclusion criteria

Exclusion criteria:

  • Visible or known injuries to eye or eye socket.
  • Non-intact periorbital skin
  • Oculomotor palsy
  • Strabismus (cross-eyedness) / impaired ocular mobility
  • Inability to refrain from alcohol, cannabis or other recreational drugs for 24 hours prior to study visit.
  • Inability or unwillingness to remove scleral contact lenses or glasses for the length of the study visit.
  • Conditions, not explicitly described, identified by clinical exam, which would make achieving a measurement impractical or uncomfortable for the participant.

What researchers measure

Primary outcomes

  1. Reliability of the iTremor device to measure ocular microtremor (OMT) in a diverse US population.

    To establish efficacy (performance/reliability) of iTremor to measure ocular mircotremor (OMT) reported in Hertz. Intra-operator, intra-device reliability will be assessed via repeated measures taken periprocedurally at one visit, utilizing the Intraclass Correlation Coefficient statistical tool (reported via single measures and average measures).

    Time frame: Repeated measures to be performed periprocedurally during a single visit (Day 1)

Secondary outcomes

  1. Reliability of the iTremor device to measure ocular microtremor (OMT) across operators.

    To establish efficacy (performance/reliability) of iTremor to measure ocular microtremor (OMT) reported in Hertz. Inter-operator, intra-device reliability will be assessed across different operators via repeated measures taken periprocedurally at one visit, utilizing the Intraclass Correlation Coefficient statistical tool (reported via single measures and average measures).

    Time frame: Repeated measures performed periprocedurally during a single visit (Day 1)

  2. Occurrence of adverse and or serious adverse events

    To establish safety of the device, the rate of adverse events and serious adverse events believed to be procedure or device related will be evaluated. The timeframe for assessment of events is from the time of the procedure until 24 hours post procedure.

    Time frame: 24 hours from the time of the procedure.

  3. Reporting the range of ocular microtremor (OMT) values across a diverse population assessed with the iTremor device .

    Report the range of ocular microtremor (OMT) values measured and detected across a diverse population of participants ages, health status and ethnicity. Measurements will be taken with the iTremor device and results will be reported in Hertz. Measurements will be taken periprocedurally during one visit.

    Time frame: Repeated measures performed periprocedurally during a single visit (Day 1)
