Compartments Of Eyeballs

The interior of the eyeball is divided into two compartments by the lens within the eyeball.

Anterior compartment: It is small and lies in front of the lens. It is filled with aqueous humour. It is further subdivided into two parts:

• A smaller anterior chamber, between the iris and cornea.
• A larger posterior chamber, between the iris and lens.

These two portions of the anterior chamber communicate with each other through a circular aperture in the iris, the pupil.

Posterior compartment: It is large (four-fifths) and lies behind the lens. It is filled with a colourless, transparent jelly-like material called vitreous humour/vitreous body.

• The vitreous humour is enclosed in a delicate hyaloid membrane.
• Anteriorly, the vitreous body presents a shallow depression (hyaloid fossa) to accommodate the lens.
