Définition et Signification de "ora serrata"

What is "ora serrata"?

The ora serrata is the boundary region between the retina and the ciliary body in the human eye. It is characterized by a jagged or serrated appearance, hence its name. This area marks the transition from the sensory retina, responsible for visual perception, to the ciliary body, which plays a role in accommodating the lens for focusing. The ora serrata contains the last row of photoreceptor cells in the retina, known as the retinal ora, before transitioning to the non-photosensitive ciliary epithelium. Its unique structure and location make the ora serrata an important anatomical landmark in the eye.
