That’s a Scleral Ring and helps to keep the shape of the eye in fish, many reptiles, and birds. Fish don’t have round eyes (they’re shaped more like M&Ms or chocolate chips), and the ring helps support the shape when swimming. Most rings are just cartilage, but fast swimmers often have bony rings.
Your orbits are similar. The hole is where the optic nerve goes.:background_color(FFFFFF):format(jpeg)/images/article/bones-of-the-orbit/fbPkbiZTakJp2wBLS0rbw_Bony_orbit.png)
Not arguing with you, but what’s up with that “bone ring” they have in their orbit? We don’t have that.

Thank you, I had no idea that reptiles and birds have eyeball rings, too.
Based on this angle, I think you might be more correct. I thought it was recessed.
