Adaptive Optics Scanning Light Ophthalmoscopy (AOSLO) and Microperimetry (MP) Sub-study

Brief Summary

This research sub-study is to evaluate if combining images from Optical Coherence Tomography (OCT) scans with Adaptive Optics Scanning Light Ophthalmoscopy (AOSLO) and Microperimetry (MP) could show a link between structural changes in the back of the eye and vision. 10 participants that were enrolled in the COmparison of Clarus and Optos Ultrawide Field Imaging Systems for Geographic Atrophy study \[NCT05961332\] will be approached to enroll. Participants may complete OCT imaging and initial assessments during an initial visit and may return for additional procedures, including microperimetry and AOSLO imaging, within a window of up to 4 weeks.
