May 17, 2024 · Eye: Anatomy. The human eye is a sensory organ whose primary function is vision. The eye has a spheroidal shape and is structured in 3 layers: a supporting outer fibrous layer, a middle vascular layer, and an inner neural layer. The eye can also be subdivided into 3 compartments: the anterior, posterior, and vitreous chambers.
May 11, 2024 · Print. Table of Contents. Anatomy. Function. Associated Conditions. Diagnosing Problems. The lens is a curved structure in the eye that sits behind the iris.

4 days ago · It is a purely sensory nerve that conveys visual information from the eye to the brain . The nerve arises from the back of the globe exiting the orbit via the optic canal. It joins the contralateral optic nerve at the optic chiasm where medial fibers decussate before continuing as the optic tracts .
May 19, 2024 · The anatomy of the visual pathway may be divided into six separate parts (Fig. 14.1): 1. Optic nerve: This includes all of the optic nerve fiber bundles of the eye. 2. Optic chiasm: This is where the characteristic crossover of the nerve fibers of both optic nerves occurs.
