The pecten or pecten oculi is a

eyeball.[1] The pecten is believed to both nourish the retina and control the pH of the vitreous body.[2] High levels of alkaline phosphatase activity in the pecten oculi have been linked to the transport of nutrient molecules from the highly vascularized choroid into vitreous and retinal cells, thus nourishing the eye.[3] It is present in all birds and some reptiles.[4]

In the

pleated in most other birds.[7]
