3D view on vessels of a healthy minipig eye. The upper opening corresponds to the pupil as the gateway input of all light into the eye. It is interesting to see the marked abundance of vessels of the pupil which bring energy and food to the muscles to control the amount of incident light. The other large vessels are feeder vessels for the outer layers of the retina and muscles, so, that the eye quickly can perceive the environment and the creature may adapt and survive.
