Figure 6

Age-related change in AF for data acquired with the cSLO in this study (Exc.: 488 nm) and with the fundus fluorophotometer (FFP) in a previous study (Exc.: 550 nm). The FFP data was normalized to the mean qAF at 20 years of age. The interrupted curves are fits through the original data, not accounting for media absorption. High absorption of the 488-nm excitation in older lenses causes the uncorrected cSLO data to decrease for ages older than 55 years. The continuous lines are the media corrected (subscript MC) qAF's obtained using the same algorithm (Equation 2) with a coefficient of 5.56 × 10−5 for the 488-nm excitation and 1.33 × 10−5 for 550-nm excitation. The thin line (FFPMC*) is the FFP data corrected using media absorption derived from a reflectometry method.
