The conus papillaris is a feature of the reptilian eye which originates from the ventro-temporal optic nerve head and rises into the vitreous. [1] It is believed to supply retinal nutrition. [2] It is similar in function to the avian pecten oculi. [1] It is functionless in adult crocodilians, and has been almost entirely replaced by other structures in most snakes. [1]
