Ophthalmia
Ophthalmia (also called ophthalmitis) is inflammation of the eye. It results in congestion of the eyeball, often eye-watering, redness and swelling, itching and burning, and a general feeling of irritation under the eyelids. Ophthalmia can have different causes, such as infection from bacteria, viruses, fungi, or may result from a physical trauma to the eye, chemical irritation, and allergies. A bacteria infection can result in a mucus and ussecretion. Severe cases of ophthalmia can cause blindness if not treated, especially in newborns, who contract it from the environment in the womb. Treatments vary according to the nature of the cause, with minor irritations going away on their own. Types Types include sympathetic ophthalmia (inflammation of both eyes following trauma to one eye), gonococcal ophthalmia, trachoma or "Egyptian" ophthalmia, ophthalmia neonatorum (a conjunctivitis of the newborn due to either of the two previous pathogens), photophthalmia and actinic conjuncti ...

Sympathetic Ophthalmia
Sympathetic ophthalmia (SO), also called spared eye injury, is a diffuse granulomatous inflammation of the uveal layer of both eyes following trauma to one eye. It can leave the affected person completely blind. Symptoms may develop from days to several years after a penetrating eye injury. It typically results from a delayed hypersensitivity reaction. Signs and symptoms Eye floaters and loss of accommodation are among the earliest symptoms. The disease may progress to severe inflammation of the uveal layer of the eye (uveitis) with pain and sensitivity of the eyes to light. The affected eye often remains relatively painless while the inflammatory disease spreads through the uvea, where characteristic focal infiltrates in the choroid named Dalén–Fuchs nodules can be seen. The retina, however, usually remains uninvolved, although perivascular cuffing of the retinal vessels with inflammatory cells may occur. Swelling of the optic disc (papilledema), secondary glaucoma, v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photophthalmia
Photophthalmia ( pho·toph·thal·mia (''fōt″of-thal´me-ah'') ) is ophthalmia or inflammation of the eye, especially of the cornea and conjunctiva due to exposure to intense light of short wavelength (as ultraviolet light Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nm (with a corresponding frequency around 30 PHz) to 400 nm (750 THz), shorter than that of visible light, but longer than X-rays. UV radiati ...), as in snow blindness. It involves occurrence of multiple epithelial erosions due to the effect of ultraviolet rays, especially between 311 and 290 nm. Snow blindness occurs due to reflection of ultraviolet rays from snow surface. Photoretinitis is another form that can occur due to infra-red rays (eclipse burn of retina). Presentation It can present with the following: * severe burning pain * lacrimation * photophobia * blepharospasm * swelling of palpebral conjunctiva * retrotarsal folds Usually the eff ...

Neisseria Gonorrhoeae
''Neisseria gonorrhoeae'', also known as ''gonococcus'' (singular), or ''gonococci'' (plural), is a species of Gram-negative diplococci bacteria isolated by Albert Ludwig Sigesmund Neisser, Albert Neisser in 1879. It causes the sexually transmitted infection, sexually transmitted genitourinary infection gonorrhea as well as other forms of gonococcal disease including disseminated gonococcemia, septic arthritis, and gonococcal ophthalmia neonatorum. It is oxidase test, oxidase positive and aerobic, and it survives phagocyte, phagocytosis and grows inside neutrophils. Microbiological culture, Culturing it requires carbon dioxide supplementation and enriched agar (chocolate agar) with various antibiotics (Thayer–Martin agar, Thayer–Martin). It exhibits antigenic variation through genetic recombination of its pilus, pili and surface proteins that interact with the immune system. Sexual transmission is through vaginal, anal, or oral sex. Sexual transmission may be prevented throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actinic Conjunctivitis
Actinic conjunctivitis is an inflammation of the eye contracted from prolonged exposure to actinic (ultraviolet) rays. Symptoms are redness and swelling of the eyes. Most often the condition is caused by prolonged exposure to Klieg lights, therapeutic lamps or acetylene torches. Other names for the condition include Klieg conjunctivitis, eyeburn, arc-flash, welder's conjunctivitis, flash keratoconjunctivitis, actinic ray ophthalmia, X-ray ophthalmia and ultraviolet ray ophthalmia. Symptoms Conjunctivitis eye condition contracted from exposure to actinic rays. Symptoms are redness and swelling. Causes Conjunctivitis is prevalent among children of the highlands of Ecuador. The finding supports the hypothesis that prolonged exposure to the sun at altitude, in the less dense atmosphere (with the resultant lower UV absorption), is one cause of the condition. Diagnosis Management See also * Conjunctivitis * Photokeratitis Photokeratitis or ultraviolet keratitis is a painf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Rushton
Edward Rushton (1756–1814) was a British poet, writer and bookseller from Liverpool, England. He worked as a sailor aboard a slave ship as a young man, and became an abolitionist as a result. After losing his own vision, he opened a school for the blind, the oldest such school in continuous operation in the world. Early life Edward Rushton was born in Liverpool, Lancashire, England on 13 November 1756. He was enrolled at the Liverpool Free School from the age of 6 until the age of 9. He left school and at the age of 11 he became an apprentice with Messrs. Watt and Gregson, a firm that traded in the West Indies. Life at sea Rushton quickly became an experienced sailor. For example, at age 16, he took the helm of a ship which the captain and crew were about to abandon and guided them safely back to Liverpool. Because of this event, he was promoted from his apprenticeship to the position of second mate. In addition, at the age of 17 he survived the sinking of a slave ship ...

Elizabeth Blackwell Elizabeth Blackwell (3 February 182131 May 1910) was a British physician, notable as the first woman to receive a medical degree in the United States, and the first woman on the Medical Register of the General Medical Council for the United Kingdom. Blackwell played an important role in both the United States and the United Kingdom as a social awareness and moral reformer, and pioneered in promoting education for women in medicine. Her contributions remain celebrated with the Elizabeth Blackwell Medal, awarded annually to a woman who has made a significant contribution to the promotion of women in medicine. |
