Pecten
Pecten (pronunciation: pek-ten) is a term with multiple meanings in the medical field. It can refer to a part of the eye, a genus of mollusks, or a comb-like structure in various organisms.
Etymology
The term 'Pecten' is derived from the Latin word 'pecten', which means 'comb'. This is due to the comb-like appearance of the structures that this term refers to.

In the field of Ophthalmology, the Pecten Oculi is a unique structure found in the eyes of birds and some reptiles. It is a vascular structure that projects into the vitreous body from the optic disk. It is believed to provide nutrients to the avian retina, which lacks blood vessels.
