Additional structures, not directly associated with vision, are found as outgrowths of the retina in some vertebrate groups. In birds, the pecten is a vascular structure of complex shape that projects from the retina into the vitreous humour; it supplies oxygen and nutrients to the eye, and may also aid in vision.
The retina of the eye of most vertebrates contains specialized cells, called photoreceptors, that detect light. The pattern of light falling on the retina is converted into a neuronal signal that is sent to the brain, and the brain then interprets the signal, changing it back into the âpictureâ seen by the eye.
