Ciliary Processes

The ciliary processes are the part of the ciliary body which is formed by the inward folding of the various layers of the choroid; that is to say the choroid proper and the lamina basalis.

The ciliary processes are arranged in a circle, and form a type of frill behind the iris, around the margin of the lens. Together they form 60-80 radial ridges located behind the iris and around the margin of the lens.

The ciliary processes are attached by their periphery to three or four of the ridges of the orbiculus ciliaris, and are continuous with the layers of the choroid. Their opposite extremities are free and rounded, and are pointing towards the posterior chamber of the eyeball and circumference of the lens.
