Main » Eye diseases » Trachoma
Trachoma is particularly common in the Middle East and Africa, as well as other parts of the tropics. It is caused by a virus of the Chlamydia group (also known as Bedsonia). Solid colour indicates high incidence; lines indicate lower incidence.
Photo 1. Early lesions. Small pinhead-sized, pale follicles beneath the epithelium over the tarsal plates, especially in the upper lid are a characteristic feature of the disease. The so-called 'TRIC' virus may be identified at this stage, and up to the time scarring commences, in epithelial scrapings.
Photo 2. Entropion and trichiasis. Scarring of the tarsal plates may be extensive and result in entroprion of the edge of the lid. The eyelashes point inwards and rub against the cornea (trichiasis), adding to the damage already done by the virus.
Photo 3. Late corneal scarring and trichiasis.The end point of trachoma is frequently blindness due to corneal scarring and other complications.
