The post-orbital bar is a bony structure found in the skulls of many primates, located behind the eye socket (orbit). It serves to provide structural support and protection for the eyes and associated structures, enhancing the visual capabilities of these animals. This feature is particularly important for primates, as it allows for a wider field of vision and greater depth perception, which are crucial for their arboreal lifestyle. In contrast to some other mammals, primates with a post-orbital bar tend to have more forward-facing eyes, contributing to their stereoscopic vision.

The human post-orbital wall is the area around the eye socket in the skull. It helps protect and support the eye while also providing structure for facial muscles and tissue. The shape and structure of the post-orbital wall can vary among individuals due to factors like genetics and development.
