What is trachoma?

Trachoma is the world’s leading infectious cause of blindness, and is part of a group of conditions known as neglected tropical diseases (often referred to as NTDs).

The End is in Sight: our campaign to eliminate trachoma

About the campaign

Trachoma starts off as a bacterial infection that’s a bit like conjunctivitis, and can be easily treated.

But if it’s not, over time it causes scarring to the eyelid that pulls the eyelashes inward, so with every blink they scrape against the eye. This advanced form of trachoma is called trichiasis, and the pain can be so intense that many people resort to pulling out their eyelashes to reduce the agony of blinking. Over time, if it’s not treated, trichiasis can lead to blindness.

What causes trachoma?

The disease thrives where there are water shortages, poor sanitation and infestations of flies. It’s caused by repeated infection with bacteria known as ‘chlamydia trachomatis’, and it spreads through contact with infected flies and via hands, clothes or bedding that have been in contact with an infected person.

The agony and disability of blinding trachoma can lead to a cycle of poverty, limiting many people’s access to health services, education and employment.

What are the symptoms of trachoma?

The most common signs that a person is suffering from trachoma include:

  • Discharge from the eyes
  • Irritated eyes
  • Redness

Because the infection spreads via hands, clothes and bedding, it disproportionately affects women and children: globally women are 1.8 times more likely than men to be blinded by the disease. If trachoma is not treated, it can lead to trichiasis.

What is trichiasis?

Trichiasis, sometimes called advanced trachoma, is when the eyes get inflamed after repeated trachoma infections. Scar tissue builds up on the inside of the eyelid, making the eyelid tight and pulling the eyelashes inwards. When the eyelashes rub the cornea, it causes immense pain and can lead to blindness.

Did you know?

Charles Dickens‘ novel Nicholas Nickleby was inspired by a 19th-century boarding school devastated by trachoma.

The history of trachoma

How is trachoma treated?

Antibiotics

Antibiotic tablets, donated by pharmaceutical company Pfizer, are used to treat the infection. Treatment is usually repeated annually for up to five years.

Surgeons operate on a trachoma patient.

Trichiasis surgery

Advanced trachoma (trichiasis) can cause the eyelashes to turn inwards. An operation stops the eyelashes rubbing against the eyeball, and can stop people going blind.

Cleanliness and hygiene

Communities are encouraged to change behaviour that can put them at risk of trachoma, and are taught about the importance of face washing, hygiene and sanitation.

Our work to treat trachoma

Our aim is to eliminate trachoma in the countries where we work, and this goal is now closer than ever.

In April 2021, The Gambia became the second country in sub-Saharan Africa to eliminate the disease. Yet there are still 44 countries that count trachoma as a public health problem, where people are at risk of being blinded by trichiasis.

We help to control the impact and spread of trachoma by implementing the World Health Organization’s SAFE strategy: the acronym describes the four methods used to control the disease.

Trachoma prevention: the SAFE strategy

  • Surgery: to stop eyelashes from rubbing against the eyeball and helping to halt the cycle of repeated infection that can lead to blindness.
  • Antibiotics: medication, distributed via mass drug administration, treats the trachoma infection and reduces the spread of the disease. It is usually repeated annually for up to five years.
  • Facial cleanliness: teaching local communities the importance of face washing, and encouraging good hygiene to prevent the infection being spread.
  • Environmental improvements: to improve access to water and sanitation to reduce exposure and re-infection, and eliminate conditions in which flies breed.
