Iridodialysis
Iridodialysis is a localized separation or tearing away of the iris from its attachment to the ciliary body.Cline D; Hofstetter HW; Griffin JR. ''Dictionary of Visual Science''. 4th ed. Butterworth-Heinemann, Boston 1997. Cassin, B. and Solomon, S. ''Dictionary of Eye Terminology''. Gainesville, Florida: Triad Publishing Company, 1990. Symptoms and signs Those with small iridodialyses may be asymptomatic and require no treatment, but those with larger dialyses may have corectopia or polycoria and experience monocular diplopia, glare, or photophobia.Rappon JM"Ocular Trauma Management for the Primary Care Provider." Pacific University College of Optometry. Accessed October 12, 2006.

Ciliary Body
The ciliary body is a part of the eye that includes the ciliary muscle, which controls the shape of the lens, and the ciliary epithelium, which produces the aqueous humor. The aqueous humor is produced in the non-pigmented portion of the ciliary body. The ciliary body is part of the uvea, the layer of tissue that delivers oxygen and nutrients to the eye tissues. The ciliary body joins the ora serrata of the choroid to the root of the iris.Cassin, B. and Solomon, S. ''Dictionary of Eye Terminology''. Gainesville, Florida: Triad Publishing Company, 1990. Structure 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 aqueous humor then flows through the pupil into the anterior chamber. The ciliary bo ...

Asymptomatic
In medicine, any disease is classified asymptomatic if a patient tests as carrier for a disease or infection but experiences no symptoms. Whenever a medical condition fails to show noticeable symptoms after a diagnosis it might be considered asymptomatic. Infections of this kind are usually called subclinical infections. Diseases such as mental illnesses or psychosomatic conditions are considered subclinical if they present some individual symptoms but not all those normally required for a clinical diagnosis. The term clinically silent is also found. Producing only a few, mild symptoms, disease is paucisymptomatic. Symptoms appearing later, after an asymptomatic incubation period, mean a pre-symptomatic period has existed. Importance Knowing that a condition is asymptomatic is important because: * It may develop symptoms later and only then require treatment. * It may resolve itself or become benign. * It may be contagious, and the contribution of asymptomatic and pre-symptomat ...

Corectopia
Corectopia is the displacement of the eye's pupil from its normal, central position. It may be associated with high myopia or ectopia lentis, among other conditions. Medical or surgical intervention may be indicated for the treatment of corectopia in some cases.

Polycoria
Polycoria is a pathological condition of the eye characterized by more than one pupillary opening in the iris.Cassin, B. and Solomon, S. ''Dictionary of Eye Terminology''. Gainesville, Florida: Triad Publishing Company, 1990. It may be congenital or result from a disease affecting the iris. It results in decreased function of iris and pupil, affecting the physical eye and visualization. In the early history of China, double pupils were seen as a sign that a child would become a great king or sage. Epidemiology Polycoria is extremely rare, and other conditions are frequently mistaken for it. Polycoria is often congenital, however not diagnosed until adulthood. The general cause of polycoria is unknown, but there are some other eye conditions that are in association with polycoria. These include (although not often) polar cataracts, glaucoma, abnormally long eyelashes, abnormal eye development, and poor vision. There have been cases diagnosed from age 3 to adulthood. The prevale ...

Avulsion Injury
In medicine, an avulsion is an injury in which a body structure is torn off by either trauma or surgery (from the Latin ''avellere'', meaning "to tear off"). The term most commonly refers to a surface trauma where all layers of the skin have been torn away, exposing the underlying structures (i.e., subcutaneous tissue, muscle, tendons, or bone). This is similar to an abrasion but more severe, as body parts such as an eyelid or an ear can be partially or fully detached from the body. Skin avulsions The most common avulsion injury, skin avulsion often occurs during motor vehicle collisions. The severity of avulsion ranges from skin flaps (minor) to degloving (moderate) and amputation of a finger or limb (severe). Suprafascial avulsions are those in which the depth of the removed skin reaches the subcutaneous tissue layer, while subfascial avulsions extend deeper than the subcutaneous layer.Jeng, S.F., & Wei, F.C. (1997, May). Classification and reconstructive options in foot plant ...

Water Balloon
A water balloon or water bomb is a balloon, often made of latex rubber, filled with water. Water balloons are used in a summer pastime of cooling off through water balloon fights. Water balloons are also popular for celebrations, including celebrating Holi and Carnival in India, Nepal, and several other countries. Types Water balloons are common in sizes from though larger sizes are available. Typically water balloons are sold in quantity and often include a filling nozzle in the packaging. Many of the low cost brands use small water balloons and generic nozzles which both tend to be difficult to use. Another form of water bomb is a sheet of paper folded to form a container capable of holding water. These are then filled and used in a similar way to latex versions. Gas balloons (air or helium types) may be used as water balloons, but are not typically preferred because the balloon wall thickness is different. A water balloon is designed to be filled up to the approximate ...

Boxing
Boxing (also known as "Western boxing" or "pugilism") is a combat sport in which two people, usually wearing protective gloves and other protective equipment such as hand wraps and mouthguards, throw punches at each other for a predetermined amount of time in a boxing ring. Although the term "boxing" is commonly attributed to "western boxing", in which only the fists are involved, boxing has developed in various ways in different geographical areas and cultures. In global terms, boxing is a set of combat sports focused on striking, in which two opponents face each other in a fight using at least their fists, and possibly involving other actions such as kicks, elbow strikes, Knee (strike), knee strikes, and headbutts, depending on the rules. Some of the forms of the modern sport are western boxing, Bare-knuckle boxing, bare knuckle boxing, kickboxing, Muay Thai, muay-thai, lethwei, savate, and Sanda (sport), sanda. Boxing techniques have been incorporated into many martial ar ...

Airbag
An airbag is a vehicle occupant-restraint system using a bag designed to inflate extremely quickly, then quickly deflate during a collision. It consists of the airbag cushion, a flexible fabric bag, an inflation module, and an impact sensor. The purpose of the airbag is to provide a vehicle occupant with soft cushioning and restraint during a collision. It can reduce injuries between the flailing occupant and the interior of the vehicle. The airbag provides an energy-absorbing surface between the vehicle's occupants and a steering wheel, instrument panel, body pillar, headliner, and windshield. Modern vehicles may contain up to 10 airbag modules in various configurations, including: driver, passenger, side-curtain, seat-mounted, door-mounted, B and C-pillar mounted side-impact, knee bolster, inflatable seat belt, and pedestrian airbag modules. During a crash, the vehicle's crash sensors provide crucial information to the airbag electronic controller unit (ECU), including colli ...

Bungee Cord
Bungee cords equipped with metal hooks A bungee cord (sometimes spelled bungle; also known as a shock cord) is an elastic cord composed of one or more elastic strands forming a core, usually covered in a woven cotton or polypropylene sheath. The sheath does not materially extend elastically, but it is braided with its strands spiralling around the core so that a longitudinal pull causes it to squeeze the core, transmitting the core's elastic compression to the longitudinal extension of the sheath and cord. Specialized bungees, such as some used in bungee jumping, may be made entirely of elastic strands. Uses upA child on a bungee cord device in Moscow, Russia Bungee cords have been used to provide a lightweight suspension for aircraft undercarriages from before World War I, and are still used on many small homebuilt aircraft where weight remains critical. Bungee cords were also used in parachuting to assist in opening the old-style parachute container after the ripcord wa ...

Bottle Cap
A bottle cap or bottle top is a closure for the top opening of a bottle. A cap is sometimes colourfully decorated with the logo of the brand of contents. Plastic caps are used for plastic bottles, while metal with plastic backing is used for glass; plastic caps are commonly made from PE or PP, whilst metal caps are usually either steel or aluminum. Plastic caps may have a pour spout. Flip-Top caps like Flapper closures provide controlled dispensing of dry products. Caps for plastic bottles are often made of a different type of plastic from the bottle. A cork is another type of closure for the top of a bottle. Types Caps were originally designed to be pressed over and around the top of a glass bottle to grab a small flange on the bottleneck. Crown cork The crown cork was patented by William Painter on February 2, 1892 (U.S. Patent 468,258). It had 24 teeth and a cork seal with a paper backing to prevent contact between the contents and the metal cap. The current versio ...

Bed Rest
Bed rest, also referred to as the rest-cure, is a medical treatment in which a person lies in bed for most of the time to try to cure an illness. Bed rest refers to voluntarily lying in bed as a treatment and not being confined to bed because of a health impairment which physically prevents leaving bed. The practice is still used although a 1999 systematic review found no benefits for any of the 17 conditions studied and no proven benefit for any conditions at all, beyond that imposed by symptoms. In the United States, nearly 20% of pregnant women have some degree of restricted activity prescribed despite the growing data showing it to be dangerous, causing some experts to call its use "unethical". Medical uses Extended bed rest has been proven to be a potentially harmful treatment needing more careful evaluation. Pregnancy Women who are pregnant and are experiencing early labor, vaginal bleeding, and cervix complications have been prescribed bed rest. This practice in 2013 wa ...

Fireworks
Fireworks are a class of Explosive, low explosive Pyrotechnics, pyrotechnic devices used for aesthetic and entertainment purposes. They are most commonly used in fireworks displays (also called a fireworks show or pyrotechnics), combining a large number of devices in an outdoor setting. Such displays are the focal point of many cultural and religious Celebration (party), celebrations. Fireworks take many forms to produce four primary effects: noise, light, smoke, and floating materials (confetti most notably). They may be designed to burn with colored flames and sparks including red, orange, yellow, green, blue, purple and silver. They are generally classified by where they perform, either 'ground' or 'aerial'. Aerial fireworks may have their own Air propulsion, propulsion (skyrocket) or be shot into the air by a Mortar (weapon), mortar (aerial shell). Most fireworks consist of a paper or Card stock, pasteboard tube or casing filled with the combustion, combustible materia ...
