ciliary processesOphthalmology The extensions or projections of the ciliary body that secrete aqueous humor
About 70 ridges, some 2 mm long and 0.5 mm high, arranged meridionally and forming the pars plicata of the ciliary body. The ciliary processes consist essentially of blood vessels which are the continuation forward of those of the choroid. The region of the ciliary processes is the most vascular of the whole eye. The ciliary epithelium of the processes, which projects from the ciliary body, is involved in the secretion of aqueous humour. See diffusion; aqueous rate of outflow humour; stria; active transport; ultrafiltration.
