The Ora Serrata is the anatomical junction between the retina and which structure?

• A. Retina and ciliary body
• B. Cornea and sclera
• C. Choroid and retina
• D. Iris and lens

Answer: (A)

The Ora Serrata marks the anterior end of the retina, where the neural retina transitions to the nonvisual layer of the ciliary body. In other words, it is the boundary between the retina and the ciliary body epithelium, not with the choroid, cornea, sclera, iris, or lens. This junction defines where the retina ends and the ciliary part of the eye begins, which is why it’s the correct description for the Ora Serrata.
