Autofluorescence Imaging: Autofluorescence imaging with blue and green light and, multicolor imaging
Infrared reflectance imaging: Infrared reflectance imaging, 30° Field of View
OCT imaging: OCT Imaging Volume and Line Scans
OCTA imaging: OCT Angiography, volume and SCOUT scan
Study summary
The goal of this pilot study is to compare image quality between the investigational devices (R1 and HighRes OCT) and the SPECTRALIS (cleared) in adult participants with normal and/or pathology eyes.
Participants will be imaged with different imaging modalities and scan protocols on all study devices.

Primary outcome measure(s)
cSLO Image quality grading — 6 months after image acquisition Good: Good focus, even illumination, optimal exposure Average: The image is of sub-optimal quality, where there are issues with focus, illumination, or exposure, but the image still allows assessment of clinically relevant content Poor: Clinically relevant features are not visible, images are not clinically useful
Visability of key anatomical structures — 6 months after image acquisition Visibility of
OCT image:
1. Difference in reflectivity between the outer retino-choroidal complex and vitreous
2. The vitreo-retinal interface
3. Difference in reflectivity between retinal nerve fiber layer and vitreous
4. Difference in reflectivity between plexiform layer and vitreous
5. Multiple layers within the outer retino-choroidal complex
6. The ganglion cell layer
7. Difference in reflectivity between outer nuclear layer and vitreous
8. External limiting membrane
9. Choroidal/scleral interface
OCTA image:
1. Foveal avascular zone
2. Large vessels: 1st order vasculature, if applicable
3. Medium vessels: 2nd and 3rd order vasculature
