What is the shape of the ciliary body in the eye?

The shape of the ciliary body is best described as triangular. This anatomical structure is located between the iris and the choroid, forming a ring around the lens. The triangular configuration arises from the placement of its three distinct components: the ciliary process, ciliary muscle, and the ciliary body itself, which collectively contribute to its overall triangular silhouette. The muscle fibers allow for the accommodation of the lens, adjusting its shape for focusing on objects at varying distances. The broader base of the ciliary body faces the anterior chamber, while the apex points posteriorly toward the vitreous body, reinforcing its triangular appearance. This unique shape plays a critical role in the functionality of the eye, supporting both accommodation and the production of aqueous humor.
