Fundus imaging of infant of Fig. 3 with blue-light excitation. Left: raw image obtained with combined RGB chip readouts of CCD detector array. First column: reflection images derived from raw image via selective B- and G-chip readouts, respectively, and subsequent FFT filtering (same settings as for Fig. 3). Second column: B and G absorption images derived from reflection images. Right column: MPOD line profiles obtained along meridians running horizontally through the center of the macula. Note that the MPOD level of $\sim 0.2$ in the center of the MP distribution is about twice as high as the level obtained with white-light excitation (shown in Fig. 3).
