Fluorescence Intensity of fluorescein, ICG, and combination. Average fluorescence intensity was detected using fluorescein and ICG capture mode on standard solutions of BSS, F-BSS, ICG-BSS, and COMBO at equal molar concentrations of the dyes. (A) Using fluorescein capture mode, BSS and ICG-BSS showed little fluorescence. (A) F-BSS and COMBO showed increased fluorescence that was not statistically different from each other. (B) Using ICG capture mode, BSS and F-BSS showed little fluorescence. (B) However, while ICG-BSS showed an expected increased fluorescence, COMBO showed an unexpected larger increase in fluorescence that was statistically greater than ICG-BSS alone.
