What is suspensory ligament eye?

The suspensory ligament of the eye, also known as the ciliary zonule, is a ring-shaped structure that attaches the lens of the eye to the ciliary body. This ligament is made up of small, delicate fibers that are responsible for maintaining the shape and position of the lens within the eye.

When the ciliary muscle contracts, it causes the suspensory ligament to relax, which allows the lens to thicken and change shape, allowing for focusing on nearby objects. When the ciliary muscle relaxes, the suspensory ligament tightens, which flattens the lens and allows for focusing on distant objects.

The suspensory ligament can become damaged or stretched, leading to a condition known as lens subluxation or dislocation. This can cause visual disturbances, including blurred or double vision, and may require surgery to correct. Additionally, certain medical conditions, such as Marfan syndrome, can cause abnormalities in the structure of the suspensory ligament, leading to lens dislocation and other eye problems.
