This video was taken at the slit-lamp, and shows what the retina looks like using a hand-held 90 diopter lens. The view is less magnified than the direct scope, and allows viewing of the entire optic nerve and posterior pole. Here you can see both the “cup” (the inner divot) and “disk” (the entire round optic nerve). The movement of the slit-beam gives a stereoscopic sense of depth.
