Overview | Symptoms | Treatment | Prevention
Granular conjunctivitis; Egyptian ophthalmia
Definition:
An eye infection caused by Chlamydia trachomatis, which may result in chronic scarring and blindness if left untreated.
Causes and Risks Trachoma is caused by infection with the bacteria Chlamydia trachomatis. It has an incubation period of 5 to 12 days and begins slowly as conjunctivitis (irritation near the eye, "pink eye") which if untreated may become chronic and lead to scarring. If the eyelids become inflamed, the eyelashes may turn in and rub against the cornea and lead to ulcers, further scarring, visual loss and even blindness. Trachoma occurs worldwide -- primarily in rural settings among developing countries. It frequently affects children, although the consequences of scarring may not be evident until later in life. While trachoma is rare in the United States, certain populations marked by poverty, crowded living conditions and/or poor hygiene are at higher risk for this illness. Trachoma is acquired through direct contact with eye or nose-throat secretions from affected individuals and inanimate objects which may have been in contact with these secretions, such as towels or clothes can also spread the disease. In addition, certain flies which have fed on these secretions can transmit trachoma.
