![Retina. Coloured scanning electron micrograph (SEM) of a resin cast of the retina. Blood vessels (red, purple) radiate out from the optic disc (yellow). The optic disc is the area where the optic nerve and blood vessels enter the eye. Due to this, it has no light-sensitive cells and is the cause of the blind spot. The cast was made by injecting resin into the blood vessels, followed by chemical digestion of the surrounding tissues. [source]](http://25.media.tumblr.com/tumblr_lh2gh1KrOa1qa6reco1_400.jpg)

![Retinal pigment epithelium precursor cells
Human embryonic stem cells differentiating into precursors cells of the retina. Nuclei are in blue. Pink indicates the presence of Pax6, a protein found in retinal tissue. The retinal pigment epithelium is the tissue responsible for macular degeneration, the most common cause of blindness.

This unusual image is a photomicrograph of a three-day-old zebrafish retina. This is a lateral view of the whole zebrafish eye, (analogous to looking directly into ones eye from the front). The image shows the lens in the centre surrounded by retinal stem cells in red and differentiating neurons in purple. The symmetrical nature of this image was achieved by reflecting the top half of the image across the origin. This is representative of true data as the zebrafish retina is very symmetrical photoreceptor organ.

Domestic chicks have a tetrachromatic colour vision, while humans have a trichromatic one. In fact in a chick retina there are four types of single-cone photoreceptor sensitive to red, green, blue and violet.](http://25.media.tumblr.com/tumblr_l99i8v6KXC1qa6reco1_500.jpg)
