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