Anatomy of the eye
General characteristics
Case 5 1
, The adult eye is a complex organ
contained within the orbital cavity
(composed of 7 bones). Each eye has
multiple layers and chambers and is
surrounded by 6 extraocular muscles.
Layers of the eye:
Fibrous layer: sclera and
cornea
Vascular layer (the uvea):
choroid, ciliary body, and iris
Neural layer: retina and optic
nerve
Chambers of the eye:
Anterior: between cornea and Components of the orbit:
iris 7 extraocular muscles:
Posterior: between iris and Levator palpebrae superioris
lens
Superior oblique
Vitreous: between lens and
Inferior oblique
posterior eye wall
Lateral rectus
Medial rectus
Inferior rectus
Superior rectus
Lacrimal apparatus:
Lacrimal glands and their associated
ducts
Produce tears to provide lubrication
Nerves and blood vessels
Function: sense of sight
Refractive media directs and refracts light to the retina. Light travels through the:
Cornea
Lens
