Intalight Reference Database Protocol for VG200D

The goal of this study is to capture VG200D OCT and OCTA scans on at least 350 normal, healthy eyes from individuals with an average age between 55-60 years of age that come from a wide range of ethnicities and races to roughly approximate the US population. This data will be used to create distribution curves for each measurement parameter and to determine the cut-off values at the 1%, 5%, 95% and 99% values for each measurement parameter. Cut-off values will be determined using a non-parametric method based on the distribution directly. Each measurement parameter distribution and associated cut-off values will be used to create a 'Reference Database' that will be used to provide feedback to clinicians using the device. When the user captures a scan on a patient, the software will indicate where a given measurement value falls within this distribution. Values between the 5% and 95% are colored green and labelled 'within normal limits', values between the 1% and 5% and between the 95% and 99% are colored yellow and labelled 'borderline', and values below the 1% and above the 99% are colored red and labelled 'outside normal limits'. These classifications aid the clinician in interpretation of the scan data by providing information where a given patient falls within the Reference Database distribution. These values are based on a comparison to the Reference Database and should be used to aid clinical decisions in combination with other clinical information available, they should not be used as the sole basis for clinical decisions.
