Outcome results

Primary

Full Retinal Thickness Measurement

Full Retinal Thicknesses Measurement

Time frame: 1 Hour

Population: Glaucomatous eyes were not scanned and analyzed in the Full Retina Thickness portion of the study. Since the imaging is done in a different area of the eye compare to Retinal Nerve Fiber Layer participants analyzed will be different between these measurement areas.
