Fovea, human retina, light micrograph

Référence de la vidéo 11944418
Human retina. Light microscope footage showing a section through the retina of the human eye, beginning at the fovea, and then moving downwards out of the foveal region. The inner surface of the retina is to the left, and the outer choroid layer is to the right. Left of the choroid layer is the photoreceptor layer of light-sensitive rods and cones. The fovea is a depression in the retinal surface where the photoreceptor layer is composed of densely-packed colour-sensitive cones, for sharp central vision. The area lacks blood vessels and its inner layers are pushed laterally, presenting less of a barrier to light. Magnification unknown.
