In vivo morphological analysis and retinal layering with cSLO angiography and SD-OCT imaging.

(A–C) Gerbillus perpallidus, (D–F) Meriones unguiculatus, and (G–I) Phodopus campbelli. cSLO en-face imaging of the vascular pattern using (A, D, G) ICG angiography mode (795 nm with barrier filter at 800 nm) depicts both retinal and choroidal structures. Black line depicts OCT scan direction. (B, E, H) FLA displays large retinal vessels and capillaries. Besides, choroidal vessels are visible in the visual steak region as different retinal layering allows light at λ = 488 nm to better penetrate the RPE/choriocapillary complex. (C, F, I) In vivo cross-sectional SD-OCT images show an increased retinal thickness in the visual streak region, indicating a specialized retinal region (arrows). ONL, outer nuclear layer; RPE, retinal pigment epithilium.
