Eyeball (Latin)

The choroidea of the oculus is located between the sclera and retina and is filled with numerous vascular bundles which supply the outer portion of the retina. Posterior to the iris and anterior portion of the sclera is a thickening of muscular and epithelial tissue known as the corpus ciliare. The final component of the vascular layer is the pigmented iris which contains a central aperture known as the pupilla. The retina forms the inner layer of the eye and is composed of a non-visual part (pars caeca) and optic part (pars optica). Located posterior to the lens and enveloped by the retina is a compartment known as the camera postrema/vitrea which is occupied by a semi-solid/jelly-like structure known as the corpus vitreum. Embedded within the meshes of the corpus vitreum is a fluid-like substance known as humor vitreus. Together these structures allow for the passage of light to the retina and provide structural support to the lens anteriorly.
