Zonular fibers, also known as suspensory ligaments or zonules of Zinn, are tiny, thread-like structures in the eye. They:
- Connect the lens to the ciliary body: Zonular fibers attach the crystalline lens to the ciliary body.
- Suspend the lens: They hold the lens in place, allowing it to change shape for focusing.
- Transmit forces: Zonular fibers transmit forces from the ciliary muscles to the lens, enabling accommodation.
Zonular fibers play a crucial role in:
- Lens accommodation: They help change the lens shape for near or far vision.
- Maintaining lens position: They keep the lens centered and stable.
Dysfunction or damage to zonular fibers can lead to vision problems, such as:
- Lens subluxation or dislocation
- Vision disturbances
Zonular fibers are an essential part of the eye’s anatomy, supporting the lens and enabling clear vision.
