Eye anatomy
The eye combines optical surfaces, aqueous and vitreous compartments, vascular supporting tissues and a neural retina that converts light into signals sent along the visual pathway.

Optical pathway
Light passes through the cornea, aqueous humor, pupil, lens and vitreous to reach the retina. Cornea and lens provide most refraction.
Anterior chamber
Aqueous humor is produced by the ciliary processes and circulates through anterior segments before exiting mainly through trabecular and uveoscleral pathways.
Retina
Rods and cones transduce light; bipolar and ganglion cell pathways process the signal. Ganglion axons form the optic nerve.
Ocular coats
Fibrous sclera and cornea, vascular uveal structures and neural retina provide distinct mechanical, metabolic and sensory functions.
