Brief Summary

Precision of OCT- and OCTA-based Ocular Measurements

Detailed Description

The purpose of this study is to assess precision of measurements of vascular structures and the anatomical structures of the posterior pole of the eye based on OCTA and OCT scans in normal subjects, glaucoma patients, and retina patients, and to assess measurements of corneal layers based on corneal OCT scans in normal subjects and cornea patients.
