What is trachoma?
Trachoma is an eye infection caused by the bacterium Chlamydia trachomatis. If not treated, this infection can cause eyelids to turn inwards, so that eyelashes rub on the eyeball, damaging the surface of the eye. This is called trichiasis, and is very painful. Repeated infections can cause blindness.
What causes trachoma?
The bacteria that causes trachoma is spread through direct contact with fluid from the eyes and nose of infected people. The bacteria can also be on personal items such as facecloths. Flies that have been in contact with infected eyes can also carry the bacteria between people.
As trachoma is easily transmitted between children, the condition often starts in childhood, but anybody can get infected at any age. People who have repeated infections can go blind in their 30s.
Trachoma is more common in areas where there is:
- a lot of people living close together
- poor access to water
- poor toilet facilities
- poor hygiene.
Infected eyes might seem sticky, or feel itchy, or be painful. In later stages a person might feel as if they have sand in their eyes.
Health practitioners can diagnose trachoma using magnifiers and a flashlight. They might also take photographs of the eyes.
Australia uses the World Health Organization recommended SAFE strategy. This consists of:
- Surgery - eyelid surgery corrects inturning of eyelashes
- Antibiotics - to treat infection
- Facial cleanliness - to stop infection spreading to others, and reduce re-infection
- Environmental improvements – including improved sanitation and water facilities for households and communities.
Australian health practitioners follow national guidelines to manage trachoma.
These guidelines include simple steps you can take to prevent the spread of infection. These include teaching children good hygiene (thorough face-washing and hand-washing) and making sure family members don’t share towels and facecloths.
Aboriginal and Torres Strait Islander communities
Some Aboriginal and Torres Strait Islander communities have high rates of trachoma.
Health services can provide information on prevention and treatment of trachoma, and refer people to eye specialists.
