body image the total concept, including conscious and unconscious feelings, thoughts, and perceptions, that a person has of his or her own body as an object in space independent and apart from other objects. The body image develops during infancy and childhood from exploration of the body surface and orifices, from development of physical abilities, and from play and comparison of the self with others. Changes in body image are particularly important in adolescence when attention is focused on appearance and attractiveness and relations with others. Body image is strongly influenced by parental attitudes that give the child a perception of certain body parts as good, clean, and attractive, or bad, dirty, and repulsive. The evolution of body image continues throughout life and incorporates such factors as a person's style of dress, hair style, and use of makeup, which symbolize social and professional status and other feelings about the self.

Many clinical syndromes involve disturbances of body image. Disturbed body image is a nursing diagnosis that was approved by the North American Nursing Diagnosis Association, defined as confusion in the mental picture of one's physical self. Surgery or trauma involving disfigurement or loss of a body part can be very threatening to a patient. Diseases involving a loss of body function, such as stroke syndrome, paraplegia, quadriplegia, coronary heart disease, and bowel or bladder incontinence, and diseases involving disfiguring skin lesions or the feeling of “rotting away” as in cancer or gangrene, can all cause changes in body image. Body image is frequently disturbed in schizophrenia, and patients may feel that their body or its parts are changing in size or shape or are ugly or threatening. Rape or violent physical assault can disturb the feeling of being secure in one's own body. Changes in body image involving sexual attractiveness or sexual identity, such as surgery or trauma involving the genitals or breasts and tubal ligation, hysterectomy, or vasectomy, can be especially difficult for the patient to deal with. Intrusive therapeutic or diagnostic procedures, such as insertion of a nasogastric tube, bladder catheterization, administration of intravenous fluids, endoscopy, and cardiac catheterization, can also threaten a patient's body image.

The reaction of a patient to an alteration in body image can include mourning the loss of the former body image, fear of rejection by significant others, hostility, and experiencing of “phantom” sensations from missing body parts. Patients with less ability to cope with their loss may respond with denial or depression. This can lead to a rejection of the altered body image and feelings of depersonalization that can involve avoidance of interpersonal contact and an unwillingness to discuss the deformity or to accept corrective medical treatment or vocational rehabilitation.

Mentioned in: Cataracts, Uveitis

ciliary body 

Part of the uvea, anterior to the ora serrata and extending to the root of the iris where it is attached to the scleral spur. It comprises the ciliary muscle and the ciliary processes and is roughly triangular in sagittal section. The whole ciliary body forms a ring. The part just beyond the ora serrata is smooth and is thus known as pars plana (orbiculus ciliaris). Anterior to this lies a region of ridges, which are the ciliary processes; this region is called the pars plicata (corona ciliaris). From the sclera inward the ciliary body consists of: the supraciliaris (supraciliary layers) which is made up of strands of collagen containing melanocytes and fibroblasts; the ciliary stroma which contains blood vessels, melanocytes and the ciliary muscle; and the ciliary epithelium which comprises an inner non-pigmented layer and an outer pigmented layer and is a continuation of the internal limiting membrane of the retina and of the retinal pigment epithelium, respectively. The cells of these layers (particularly those of the non-pigmented layer) appear to be actively engaged in ion and water transport and the production of aqueous humour. See angle recession; cyclitis; iridodialysis; supraciliary space; stria; ultrafiltration.

Intraocular medulloepitheliomas are congenital tumors of the nonpigmented ciliary epithelium, typically diagnosed during the first decade of life.
Free tumor cells express TGF-[beta] and VEGF, are spread via the aqueous humor between the vitreous base and ciliary epithelium for 360[degrees], migrate through the pupil where they become implanted into the iris, and cause neo vascularization of the iris.
Topics include transport in the anterior segment, (including aquaporins and water treatment in the cornea, corneal epithelial epithelial ion transport, Vitamin C transport, and management of function), transporters of the ciliary epithelium (including mechanisms of aqueous humor formation), lens transporters (including advances in treatment of cataract), transport across the blood-retinal barrier, transport across the retinal pigment epithelium (including treatment for age-related conditions), transporters in the retina) genetic variants of ocular transporters, and ocular drug delivery.
