Symptoms And Progression Of Trachoma

Trachoma is a type of eye disease caused by infection with a bacterium known as Chlamydia trachomatis. The condition affects both eyes, and it is contagious, spreading from person to person through contact with infected clothing or bedding. The disease can also be transmitted through skin-to-skin contact, including handshakes, with individuals who have trachoma. Trachoma is the most common cause of preventable blindness throughout the world, and approximately two million cases of trachoma-induced blindness have been reported. The disease is prevalent in rural areas of Africa, South America, Asia, and Australia. Most cases of blindness caused by trachoma have occurred in Africa. Treatment for the condition includes antibiotics such as tetracycline and azithromycin, and these may be enough to eliminate the infection. In the later stages of trachoma, surgical intervention may be available to limit the formation of scar tissue and preserve existing vision.

The signs discussed below are some of the most frequent symptoms associated with early and late stages of trachoma.

Irritated And Itchy Eyes And Eyelids

Irritated and itchy eyes and eyelids are common in the early stages of trachoma. As the condition worsens, irritation and itchiness typically increase over time. The upper eyelids tend to be more irritated and itchy than the lower eyelids, and the upper eyelids often become thicker as irritation increases. Swelling of the eyelids is frequently seen, and the eyelids and eyelashes may turn inward during the late stages of the infection, scratching the cornea and intensifying irritation. Eye specialists can evaluate the severity of any irritation and the potential for eye damage, and they may be able to prescribe certain eye drops that could reduce itching and calm inflammation. For trachoma patients whose eyelashes have started to rub on and irritate the cornea, a surgical procedure called epilation might be considered. This procedure removes the lashes. If this operation is not available in the patient's location, doctors usually recommend placing an adhesive bandage over the eyelashes to prevent them from touching the eye.
