<i>In vivo</i> fundus imaging.

<p>cSLO fundus images of (<b>A</b>) human, (<b>B</b>) mouse, and (<b>C</b>) Meriones unguiculatus. (<b>A–C</b>) D = dorsal, V = ventral. (<b>A</b>) Native infrared (λ = 830 nm) SLO image of one researcher's right eye illustrates the sparse vascularization of the macular region. (<b>B</b>) Fluorescein angiography (FLA) (488 nm, barrier filter at 500 nm) reveals the evenly distributed retinal blood vessels in mice. (<b>C</b>) FLA image of Meriones unguiculatus visualizes the horizontal sparse vascular band denoting the specialized retinal region dorsal to the optic disc.
