Test Procedure

1. Obtain the Heidelberg Spectralis optic nerve report. The report must show an image of the optic nerve head and the superimposed peripapillary ring where peripapillary segmentation was performed.
2. Measure ring diameter
3. Measure horizontal optic nerve diameter
4. Measure vertical optic nerve diameter
