Many people don鈥檛 know this, but Indigenous Australian children are than non-Indigenous children.
Yet, at the population level, Indigenous people at the age of 40 three times that of non-Indigenous Australians. Rates of blindness are six times higher among Indigenous adults.
The prevalence of vision problems in Indigenous people is a result of cataracts, diabetic eye disease and a disease non-Indigenous children don鈥檛 get 鈥� trachoma. In fact, trachoma disappeared from mainstream Australia more than 100 years ago with improved hygiene facilities, water infrastructure and living conditions.
Yet, in some areas, 4% of Indigenous children aged from five to nine years old . In the Northern Territory, that rate is 5%, which is considered an endemic level.

What is trachoma?

We used to call trachoma sandy blight (the eyes feel gritty, as if full of sand). It is the world鈥檚 .
Trachoma is caused by the bacterium Chlamydia trachomatis, which leading to scarring. The scars cause the eyelashes to turn inward and scratch the eye, which is intensely painful and made worse by blinking.
Eventually, if left untreated, all the scratching from the lashes will result in the cornea 鈥� the transparent layer at the front of the eye 鈥� going cloudy and the person having irreversible blindness.
Trachoma leads to eyelashes turning inwards and scratching the eye, leading to blindness.
,
Trachoma easily spreads from one child to another through infected eye and nose secretions.
Unlike other infectious diseases, a single episode of trachoma is often not uncomfortable or noticed as being any different from just a runny nose. Nor is a single episode such a problem for the individual child.
The main issue is that children , which keeps the inflammation present. A child may have of reinfection during their childhood and around 160 to 180 infections until the resultant scarring causes blindness.
Each episode of infection , but repeated reinfection turns into a continuing infection and disease. The longer the inflammation goes on, the worse the discomfort and more severe the scarring. And the more severe the scarring the greater the risk of blindness.

Where does trachoma exist?

Australia remains the only high-income country to still have trachoma. Although it doesn鈥檛 exist in mainstream Australia, trachoma persists in remote Aboriginal communities that still lack safe washing facilities and have notoriously poor and chronically overcrowded housing.
Young children with constant eye and nose secretions in remote endemic communities and washing a child鈥檚 face whenever it鈥檚 dirty (with eye and nose secretions) is not common.
But Australia is making progress. In 2009, the Australian government committed to eliminating trachoma by 2020. At that time, between 15% and 20%. Data from 2015 show a massive drop, in endemic areas at 4.6%.

Of equal importance is the dramatic reduction in the number of communities with trachoma. More than 150 of the 200 or so at-risk communities no longer have trachoma and there are only a small number with high rates. These hotpots are mainly in and around Central Australia.
Globally, trachoma affects people with poor personal and community hygiene. In 2016, an are at risk of trachoma in 42 countries 鈥� mainly in sub-Saharan Africa, but also in countries such as Afghanistan, India, Brazil, Colombia and some Pacific Island nations.
The World Health Organisation has set the goal of by 2020. Countries such as Morocco, Ghana, Iran, Mexico, Nepal, China and Cambodia have eliminated trachoma over the last ten years.

What are the treatments?

The World Health Organisation to eliminate trachoma. This includes: surgery to correct the inward eye lashes (S); antibiotics to reduce levels of infection (A); promotion of facial cleanliness to stop transmission (F); and environmental improvements in water and sanitation (E).
In Australia, the antibiotic of someone with trachoma, or everybody in affected communities.
This brings down the level of infection, but without stopping the possibility of transmission, trachoma will bounce back. This is why keeping every child鈥檚 face clean is so important. The essential and sustainable strategy of maintaining trachoma elimination comes down to having clean faces, which goes with access to safe and functional bathrooms and washing facilities.

Improved hygiene will also help reduce other common and very serious infections in remote Indigenous communities.
There are currently effective health promotion activities in Australia such as 鈥淐lean Faces, Strong Eyes鈥�. Bodies such as the Indigenous Eye Health group at the University of Melbourne continue to work closely with community groups to build on this work.
