Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To determine the area under the Receiver Operator Characteristic Curve (AUC) for the Ganglion Cell Analysis (GCA) average thickness.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To determine the area under the Receiver Operator Characteristic Curve (AUC) for the following GCA parameters:

1. Minimum thickness
2. Supero-temporal thickness
3. Superior thickness
4. Supero-nasal thickness
5. Infero-temporal thickness
6. Inferior thickness
7. Infero-nasal thickness
