Primary outcome measure(s)
Reliability of the iTremor device to measure ocular microtremor (OMT) in a diverse US population. — Repeated measures to be performed periprocedurally during a single visit (Day 1) 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).
