NIR reflectance images of the retina in response to patterned visual stimuli. (A) Baseline fundus reflectance image of the left eye at 750 ± 10 nm. Focus was maximized for clarity of the surface retinal vasculature. Superior (S) and temporal (T) directions are shown in the bottom left corner. Field of view spans approximately 35° in the nasal–temporal axis. (B) Difference images (top), show the change in NIR reflectance in response to visual stimulation at 540 nm. For reference, the stimulus positions are overlaid on the baseline fundus image below. The reflectance changes of the retina show tight spatial correlation with the spatial pattern used to stimulate the retina. Dark regions: relative decrease in NIR reflectance. Difference images were cropped 3% on the top and bottom for display purposes.
