**Core Concept**
The anteroposterior stability of the eyeball is crucial for maintaining clear vision and preventing damage to the delicate ocular structures. This stability is achieved through a combination of anatomical and physiological mechanisms that work together to prevent excessive movement of the eyeball.

**Why the Correct Answer is Right**
The primary structures responsible for anteroposterior stability of the eyeball include the rectus muscles, the orbital septum, and the suspensory ligaments (also known as the annular tendons or Lockwood's ligaments). The rectus muscles, which include the superior, inferior, medial, and lateral rectus muscles, are attached to the eyeball and the surrounding bone via tendons. The orbital septum is a fibrous membrane that covers the orbital fat and provides additional support to the eyeball. The suspensory ligaments, on the other hand, are fibrous connections that suspend the eyeball within the orbit and provide stability in the anteroposterior direction.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that the suspensory ligaments play a critical role in maintaining the anteroposterior stability of the eyeball. Damage to these ligaments can lead to globe luxation, a serious complication that requires prompt medical attention.
