ciliary

 [sil´e-ar″e]
pertaining to or resembling cilia; used particularly in reference to certain eye structures, as the ciliary body or muscle.
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. These processes radiate from the ciliary muscle and give attachment to ligaments supporting the lens of the eye.

cil·i·ar·y

(sil'ē-ar'ē),
1. Relating to cilia found widely in the animal kingdom from single-cell to more complex organisms and serving various motile and sensory functions.
See also: cilium.
2. Relating to any cilia or hairlike process, specifically the eyelashes; other ciliary structures are located on type I and II hair cells of the maculae of the inner ear, on hair cells of the organ of Corti, and on ciliated columnar epithelium of respiratory tract.
See also: cilium.
3. Relating to certain structures of the eyeball (for example, ciliary body, ciliary muscle, ciliary process, anterior ciliary vein).
See also: cilium.
4. Relating to the cilia of the pseudostratified columnar cells of the respiratory tract from the nose to the alveoli. Their synchronized beating moves the blanket of mucus overlying the respiratory epithelium. see mucociliary clearance. Viral and bacterial infections and environmental pollutants impair ciliary function. Genetic disorders causing anomalies of the dynein arms of cilia result in ciliary dyskinesia, for example, Kartagener syndrome.
See also: cilium.
5. Relating to cilia of the uterine tubes.
See also: cilium.
6. Relating to the cilia of the olfactory receptor cells that containe the olfactory receptors. Agenesis results in anosmia, for example, Kallmann syndrome.
See also: cilium.
7. Relating to motile protoplasmic extensions of some cells.
See also: cilium.

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.

Researchers suggest that the underlying reason for the improved accommodation ability may be due to the positively activated functions of three muscles in the eye: the constrictor pupillae muscle and dilator pupillae muscle working in coordination with the ciliary muscle.
