Movie S2.

Z-stack images of minimally invasive intravital imaging of the mouse retina through the sclera. The ONH is on the right side in this movie. The movie shows distinct layers in the retina, including the retinal pigment epithelium, deeper layer of the retinal vascular system, inner nuclear layer, inner plexiform layer, RGC cell bodies and dendrites in the ganglion cell layer, and RGC axons in the nerve fiber layer. Individual RGC axons commonly project to the ONH. Depth is indicated at the lower left.
