Uveitis
|
|
Uveitis The inflammation of structures of the inner eye, including the iris (the colored tissue that holds the lens of the eye) and the choroid plexus (a network of blood vessels around the eyeball). Uveitis occurs with some rheumatic diseases, including ankylosing spondylitis and juvenile rheumatoid arthritis.
RELATED TERMS--------------------------------------
Inflammation
A reaction to an injury to the body - by infection, chemicals or physical agents. The symptoms can be - depending on the location of the injury- redness, swelling, heat and pain. The purpose of the inflammation is to dilute and destroy the agent causing the inflammation. To do this, the immune system starts a cascade of actions that causes active cells to gather at the affected location. It is these cells and fluids that cause the redness, swelling, heat and pain.
Eye
The organ of sight. The eye has a number of components. These components include but are not limited to the cornea, iris, pupil, lens, retina, macula, optic nerve, choroid and vitreous.
Iris
The colored part of the eye with a hole (pupil) in the center. It regulates the amount of light entering the eye – the dimmer the lighting the more light the iris lets into the eye by widening the pupil.
Tissue
Biological tissue is a group of cells that perform a similar function.The study of tissues is known as histology, or, in connection with disease, histopathology.The classical tools for studying the tissues are the wax block, the tissue stain, and the optical microscope, though developments in electron microscopy, immunofluorescence, and frozen sections have all added to the sum of knowledge in the last couple of decades.
Lens
The lens of the eye is like an adjustable lens of a camera and focuses light rays on to the retina for sharp images. A condition called presbyopia occurs when the lens is no longer able to adjust for objects at different distances.
Choroid
This is the vascular coat between the sclera and the retina, which furnishes blood and nutrition to the outer layer of the retina.
Plexus
A network of nerves or veins.
Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.
Uveitis
The inflammation of structures of the inner eye, including the iris (the colored tissue that holds the lens of the eye) and the choroid plexus (a network of blood vessels around the eyeball). Uveitis occurs with some rheumatic diseases, including ankylosing spondylitis and juvenile rheumatoid arthritis.
Ankylosing
Undergoing ankylosis (stiffening or fusion of a joint).
Spondylitis
Inflammation of the vertebrae.
Arthritis
Inflammation of a joint, usually accompanied by pain, swelling, and stiffness, and resulting from infection, trauma, degenerative changes, metabolic disturbances, or other causes. Arthritis occurs in various forms, such as the arthritis associated with infections, osteoarthritis, or rheumatoid arthritis. Many forms of vasculitis can also be associated with arthritis.

Uracil
A nitrogenous base normally found in RNA but not DNA; uracil is capable of forming a base pair with adenine.
Urine
The waste fluid secreted by the kidneys, transported by the ureters, stored in the bladder, and voided through the urethra.
Urethra
A narrow tube that transports urine from the bladder to the outside of the body. In males, it also conducts sperm and semen to the outside.
Uterus
The uterus is a hollow, pear-shaped organ located in a woman's lower abdomen, between the bladder and the rectum, that sheds its lining each month during menstruation and in which a fertilized egg (ovum) becomes implanted and the fetus develops.
Uveitis
Ulna

Ultram
Tramadol.
Urology
The study and treatment of diseases that affect the urinary system.
