A contagious disease of the conjunctiva and cornea of the eye, producing painful sensitivity to strong light and excessive tearing.
A contagious disease of the conjunctiva and cornea, producing photophobia, pain, and lacrimation, caused by Chlamydia trachomatis.
A contagious virus disease of the eye characterized by granular conjunctivitis.
A contagious disease of the conjunctivas. It is related to psittacosis and lymphogranuloma venereum. It is characterized by conjunctival congestion, swelling of the eyelids, and may involve the entire cornea. It is the leading cause of blindness on a worldwide basis.
A contagious viral inflammation of the eyelids, common in tropical countries, which can cause blindness if the conjunctiva becomes scarred.
Chronic infection of the eye, caused by Chlamydia trachomatis, common in many tropical areas, especially where sanitation is limited; in the United States it occurs primarily in the Southwest, esp. on American Indian reservations. Early inflammation, pus, and tearing may lead to scar formation, causing blindness. Treatment is by antibiotics.
An eye infection caused by Chlamydia trachomatis bacteria. Trachoma causes inflammation of the cornea of the eye and clouding of vision. The eye becomes scarred, causing malformation of the eyelids and an abnormal inward growth of the eyelashes. The cornea, which is continually scraped by the eyelashes, hardens and becomes opaque, leading to a loss of vision. Trachoma is diagnosed by microscopic identification of the bacteria in scrapings from the eyes. Tetracycline and erythromycin are the antibiotics used to treat the infection. If the eyelids are deformed, surgery is required to restore normal appearance and function.
A chronic contagious eye disease, a severe form of conjunctivitis, caused by the virus-like organism Chlamydia trachomatis; it is common in tropical regions. The conjunctiva of the eyelids becomes inflamed, leading to discharge of pus. If untreated, the conjunctiva becomes scarred and shrinks, causing the eyelids to turn inward so that the eyelashes scratch the cornea (trichiasis); blindness usually follows. Treatment with tetracyclines is effective.
Trachoma is a severe type of conjunctivitis. This chronic contagious condition is caused by Chlamydia trachomatis, a bacterium with virus-like characteristics. The disease affects 150 million people worldwide and is common in developing countries, where it is the leading cause of preventable blindness. It may be seen in immigrant populations in developed countries, although it is usually inactive. The bacterium is transmitted by flies and causes inflammation of the conjunctiva and cornea with consequent scarring. The active disease is treated with tetracycline tablets and eye drops; cure is usually satisfactory. In theory, trachoma should be easy to eliminate. The World Health Organization, which aims to do this by 2020, is using a four-pronged strategy to tackle the disease.
A chronic, contagious form of conjunctivitis that is the leading cause of blindness in the world. It is caused by Chlamydia trachomatis, which is endemic in Africa, India, and the Middle East and is seen also in the southwestern U.S. The disease is transmitted by flies, clothing, bedding, and hands contaminated by exudate. Over time, the inflammation is followed by scarring, which causes the cornea to become opaque.
Trachoma is a chronic infectious ailment that affects the cornea and conjunctiva of the eye. It stems from the bacteria Chlamydia trachomatis and spreads through direct contact, potentially facilitated by flies. While the prevalence of this condition is low in the UK, globally, trachoma stands as the leading cause of blindness. Treatment involves the use of antibiotic medications.
A highly infectious viral condition affecting the eyelids, marked by shiny bumps on the conjunctiva, followed by significant scarring, tightening, and distortion of the eyelids, which can result in blindness.
