Topcon 3D OCT-1 Maestro Reference Database Study II

The objective of this study is to collect OCT measurement data on normal healthy eyes in order to determine the reference limits for Topcon 3D OCT-1 Maestro based on the percentile points for 1%, 5%, 95%, and 99%.

• Visual field defects consistent with glaucomatous optic nerve damage based on with at least one of the following two findings:

• On pattern deviation (PD), there exists a cluster of 3 or more points in an expected location of the visual field depressed below the 5% level, at least 1 of which is depressed below the 1% level;
