Related to ciliary process: corpus ciliare

cil·i·ar·y pro·cess

[TA]
one of the radiating pigmented ridges, usually 70 in number, on the inner surface of the ciliary body, increasing in thickness as they advance from the orbiculus ciliaris to the external border of the iris; these, together with the folds (plicae) in the furrows between them, constitute the corona ciliaris.
Synonym(s): processus ciliaris [TA]

ciliary process

any one of about 80 tiny fleshy projections on the posterior surface of the iris, forming a frill around the margin of the crystalline lens of the eye. The processes compose one of the two zones of the ciliary body of the eye and are formed by infolding of the various layers of the choroid. They secrete nutrient fluids to nourish the lens, cornea, and vitreous body. See also ciliary body.

ciliary

pertaining to or resembling cilia; used particulary in reference to certain eye structures, such as the ciliary body or muscles.

ciliary adenomas
arise from the non-pigmented inner layer of the ciliary epithelium; cause hyphema or glaucoma.
ciliary body
the thickened part of the vascular tunic of the eye, connecting choroid and iris, made up of the ciliary muscle and the ciliary processes. The processes radiate from the ciliary muscle and give attachments to ligaments supporting the lens of the eye.
ciliary body inflammation
ciliary epithelium
rostral continuation of the pars ciliaris retinae; non-pigmented, non-neural cells.
ciliary flush
dilation of deep conjunctival vessels and episcleral vessels causing perilimbal redness.
ciliary glands
sweat glands which have become arrested in their development, situated at the edge of the eyelids. Called also Moll's glands.
ciliary inflammation
cyclitis.
ciliary injection
peripheral hyperemia of the anterior ciliary vessels which produces a deep red or rose color of the corneal stroma, and must be distinguished from hyperemia of the conjunctival vessels. May spread to the perilimbic corneal tissue. Called also ciliary flush.
ciliary muscle
the smooth (mammals) or striated (birds) muscle that forms the main part of the ciliary body and and functions in accommodation of the eye.
primary ciliary dyskinesia
abnormality of ciliary function leading to diseases of respiratory and reproductive tracts including sinusitis and bronchiectasis. May be associated with cardiac displacement. See also kartagener's syndrome.
ciliary process
folded structures on the posterior aspect of the ciliary body.

ciliary reflex
movements of the pupil in accommodation.
ciliary zonules
continuations of the ciliary processes of the ciliary body connecting it to the lens. They are in close contact with the hyaloid membrane of the vitreous body.
