Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Definition: Diagnostic accuracy of OSDx compared to Clinical expert and predicate device (OSA plus) Measurement: Sensitivity, specificity, positive and negative predictive valuesTimepoint: At the time of a single clinical visit (Day 0); repeat testing in 20% of participants within 1 7 days to assess test retest reliability | — |
Secondary
| Measure | Time frame |
|---|---|
| Correlation of OSDx & predicate device parameters (TMH, MG loss %, blink rate analysis, & Lipid Layer Thickness). Differences in diagnostic parameters between OSDx & predicate device (e.g., mean TM ROC, MGD, etc.). Agreement between device-based diagnoses (OSDx & predicate device) & clinical expert diagnosis. Classification performance of the OSDx & predicate devices in subgroups of dry eye severity. Inter & Intra observer repeatability in subset of participants for OSDx device.Timepoint: Repeat testing within 1 7 days from initial visit (only in 20% subset) rest everything will be done at the time of single diagnostic visit (Day 0) | — |
