Ciliary flush.
Eye with iritis showing ciliary flush.
Iris Ciliary body Choroid.
The collarette is the thickest region of the iris, separating the pupillary portion from the ciliary portion.
The ciliary processes produce aqueous humour.
The pupillary zone is the inner region whose edge forms the boundary of the pupil. The ciliary zone is the rest of the iris that extends to its origin at the ciliary body.
Ciliary ganglion with parasympathetic fibers of ciliary nerves.
Area Nerve Superior Supraorbital nerve Supratrochlear nerve Infratrochlear nerve Inferior Infraorbital nerve Lateral Lacrimal nerve(with contribution from zygomaticofacial nerve)Circumcorneal Long ciliary nerves.
The ciliary epithelial cells of the eye probably synthesize portions of the zonules.[1].
The anterior segment or anterior cavity[1] is the front third of the eye that includes the structures in front of the vitreous humour:the cornea, iris, ciliary body, and lens.[2][3].
Along with the ciliary body and iris, the choroid forms the uveal tract.
Posterior chamber is an important structure involved in production and circulation of aqueous humor.Aqueous humor produced by the epithelium of the ciliary body is secreted into the posterior chamber, from which it flows through the pupil to enter the anterior chamber.[2].
The ciliary fibers have circular(Ivanoff),[10] longitudinal(meridional) and radial orientations.[11].
The trabecular meshwork is an area oftissue in the eye located around the base of the cornea, near the ciliary body, and is responsible for draining the aqueous humor from the eye via the anterior chamber(the chamber on the front of the eye covered by the cornea).
Ciliary flush is usually present in eyes with corneal inflammation, iridocyclitis or acute glaucoma, though not simple conjunctivitis. A ciliary flush is a ring of red or violet spreading out from around the cornea of the eye.
In paralysis of accommodation, amplitude of accommodation is either markedly reduced or completely absent(cycloplegia).[1]It may occur due to ciliary muscle paralysis or occulomotor nerve paralysis.[2] Parasypatholytic drugs like atropine will also cause paralysis of accommodation.[3].
Reduced visual acuity ciliary flush(circumcorneal injection) corneal abnormalities including edema or opacities("corneal haze") corneal staining abnormal pupil size abnormal intraocular pressure.
Segments 3, 4, 5, and 6 are all located within a compact region within the midbrain. Segments 7 and 8 each contains parasympathetic fibers that courses from the Edinger-Westphal nucleus, through the ciliary ganglion, along the oculomotor nerve(cranial nerve 3), to the ciliary sphincter, the muscular structure within the iris.
Accommodation essentially means that when the ciliary muscle contracts, the lens becomes more convex, generally improving the focus for closer objects. When it relaxes, it flattens the lens, generally improving the focus for farther objects.
Types include: Pupillary light reflex and Accommodation reflex. Although Pupillary response, where the pupil dilates or constricts due to light is not usually called a"reflex", it is still usually considered a part of this topic. Adjustment to close-range vision is known as"the near response",while inhibition of the ciliary muscle is known as the"far response".
The ciliary body is attached to the lens by connective tissue called the zonular fibers(fibers of Zinn). Relaxation of the ciliary muscle puts tension on these fibers and changes the shape of the lens in order to focus light on the retina.
In addition, some uveal regions have special functions of great importance, including secretion of the aqueous humour by the ciliary processes, control of accommodation(focus) by the ciliary body, and optimisation of retinal illumination by the iris's control over the pupil. Many of these functions are under the control of the autonomic nervous system.
Because the ciliary body produces aqueous humor, it is the main target of many medications against glaucoma. Its inhibition leads to the lowering of aqueous humor production and causes a subsequent drop in the intraocular pressure. There 3 main types of medication affecting the ciliary body:[10][11].
The posterior chamber is a narrow space behind the peripheral part of the iris,and in front of the suspensory ligament of the lens and the ciliary processes. The posterior chamber consists of small space directly posterior to the iris but anterior to the lens. The posterior chamber is part of the anterior segment[1] and should not be confused with the vitreous chamber(in the posterior segment).
The ciliary body is a ring-shaped thickening of tissue inside the eye that divides the posterior chamber from the vitreous body. It contains the ciliary muscle, vessels, and fibrous connective tissue. Folds on the inner ciliary epithelium are called ciliary processes, and these secrete aqueous humor into the posterior chamber.
The outermost layer, known as the fibrous tunic, is composed of the cornea and sclera, which provide shape to the eye and support the deeper structures. The middle layer, known as the vascular tunic or uvea,consists of the choroid, ciliary body, pigmented epithelium and iris. The innermost is the retina, which gets its oxygenation from the blood vessels of the choroid(posteriorly) as well as the retinal vessels(anteriorly).
Premature slerosis of lens or ciliary muscle weaknesses due to systemic or local cases may cause accommodative insufficiency.[1] Systemic causes of cliary muscle weakness include diabetes, pregnancy, stress, malnutrition etc.[1] Open angle glaucoma, Iridocyclitis etc. are known local causes.[1].
The pars plicata(Latin: folded portion) is the folded and most anterior portion of the ciliary body of an eye. The ciliary body is a part of the uvea, one of the three layers that comprise the eye. The pars plicata is located anterior to the pars plana portion of the ciliary body, and posterior to the iris.
The ciliary muscle receives parasympathetic fibers from the short ciliary nerves that arise from the ciliary ganglion. The sympathetic postganglionic fibers are part of cranial nerve V1(Nasociliary nerve of the trigeminal), while presynaptic parasympathetic fibers to the ciliary ganglia are from the oculomotor nerve.[7] The postganglionic sympathetic innervation arises from the superior cervical ganglia.
