Fig. 9.

Reflection-based fundus image of prematurely born infant. A distinguishable macula is not yet developed; measurable MP levels are absent. The dark spot in the upper left of the image indicates the presence of a chromophore, but its eccentricity from the optical disk is at least twice as high as for a normal infant macula, and its spectral characteristics are not consistent with a yellow chromophores such as MP.
