The Eye Series: The Ciliary Body

Book Appointment

The ciliary body is a part of the eye and is involved in many functions of the eye. 

Small projections from the ciliary body, called ciliary processes, produce aqueous humor, which is a clear fluid that fills up the space between the cornea and the lens. 

From the ciliary body, cable-like structures called zonule fibres attach to the lens. These zonule fibres help determine lens shape when focusing up close or at a distance. When focusing up close the ciliary body contracts which causes the zonule fibres to relax which in turn causes the lens to bulge outwards thereby providing extra focusing power. 

Presbyopia is a very common condition which occurs as we age and could be caused by a decrease in ciliary body contraction or increasing rigidity of the lens. These age related changes result in the lens being unable to bulge outward and increase its focusing power. Presbyopia is the reason that many people need reading glasses as they get older.
