Cross Section of an Adult Eye
This medical exhibit illustrates a sagittal section of the eye. A cross-sectional view of the eye shows:Three different layers; external layer, formed by the sclera and cornea; intermediate layer, divided into two parts: anterior (iris and ciliary body) and posterior (choroid) and the internal layer, or the sensory part of the eye, the retina. There are three chambers of the eye. The anterior chamber (between cornea and iris), the posterior chamber (between iris, zonule fibers and lens) and the vitreous chamber (between the lens and the retina). The sagittal section reveals the lens which is suspended by ligaments (called zonule fibers) attached to the anterior portion of the ciliary body.
