Notes on Different Meanings

While the core definition provided is biological, it is important to note that "oculus" has a distinct, well-established meaning in architecture, referring to a circular opening at the top of a dome or in a wall. This is a separate meaning, not a compound word. Example: The Pantheon in Rome is famous for the oculus in its dome.
