Schematic diagram of the human eye.

The anterior segment is the front third of the eye that includes the structures in front of the vitreous humour: the cornea, iris, ciliary body, and lens.^{[1] [2]}

Within the anterior segment are two fluid-filled spaces:

• the anterior chamber between the posterior surface of the cornea (i.e. the corneal endothelium) and the iris.
• the posterior chamber between the iris and the front face of the vitreous.^[1]

Aqueous humor fills these spaces within the anterior segment and provides nutrients to the surrounding structures.^[3]

Some ophthalmologists specialize in the treatment and management of anterior segment disorders and diseases.^[2]
