Trachoma - Preventing the Leading Cause of Blindness

Trachoma is more than just an eye infection; it is the world's leading infectious cause of blindness. Understanding how this neglected tropical disease spreads and recognizing its early symptoms is crucial for preventing irreversible vision loss and protecting your community.

What are the main causes of Trachoma?

• Trachoma is caused by specific serotypes of the bacterium Chlamydia trachomatis, which flourishes in environments with poor sanitation and limited access to clean water.
• This eye infection is highly contagious and spreads through direct contact with eye or nose discharge from an infected person, often via hands or clothing.
• Flies that have been in contact with infected individuals can also easily transmit the bacteria, making environmental hygiene a critical factor in its spread.

Key symptoms of Trachoma to watch for

• Early trachoma symptoms include mild itching and irritation of the eyes, light sensitivity, and a watery discharge containing mucus or pus.
• Repeated infections lead to scarring on the inner surface of the upper eyelid, a key sign used in the clinical diagnosis of trachoma.
• In advanced stages, this scarring causes the eyelashes to turn inward, a painful condition known as trichiasis that scratches the cornea and leads to blindness.

How can you prevent Trachoma effectively?

• The global elimination effort is guided by the SAFE strategy, which includes trachoma surgery to correct trichiasis and prevent further corneal abrasion.
• Antibiotics are a key component of treatment, with a single dose of azithromycin for trachoma being highly effective at clearing the active infection.
• The most crucial long-term prevention of trachoma involves promoting facial cleanliness and hygiene and improving access to clean water and sanitation to reduce transmission.
