Prevalence of trichiasis
- Measure 1.3.2
- The estimated number, and proportion of First Nations adults in at-risk communities with trichiasis.
Repeated trachoma infections can result in scarring and in-turned eye lashes, trichiasis. Early detection and treatment of trichiasis can prevent blindness (Figure 11 and Figure 12).
Figure 11: Prevalence of trichiasis, 2011 to 2022
Prevalence of trichiasis, 2011 to 2022
This dual axis combined line graph and scatter plot shows the percentage and number of Indigenous adults aged 40 and over with trichiasis, from 2011 to 2022. The chart shows that, from 2011 to 2022, the percentage of First Nations people aged 40 and over with trichiasis fell from 1.6% to 0.1%.
In 2022 less than 1% of adults in at-risk communities suffered from trichiasis.

Prevalence of trichiasis: Interactive data
This interactive visualisation shows 2 separate charts showing the prevalence of trichiasis in at-risk Indigenous communities, for First Nations people by various characteristics.
Prevalence of trichiasis in communities that screened by age, 2022
This dual axis combined vertical bar chart and scatter plot compares the percentage and number of First Nations people with trichiasis in at-risk Indigenous communities, in two broad age groups, and for all Australians aged 15 and over in 2022. The chart shows that there were 8 First Nations people aged 40 and over with trichiasis, a prevalence rate of 0.11%. There were no Australians aged 15–39 with trichiasis in these communities.
Prevalence of trichiasis in communities that screened among those aged 40 and over, by jurisdiction, 2022
This dual axis combined vertical bar chart and scatter plot compares the number and percentage of Indigenous adults aged 40 and over with trichiasis, for 3 jurisdictions in 2022. The chart shows that the prevalence of trichiasis in First Nations people aged over 40 was highest in Western Australia and South Australia (both 0.2%). Norther Territory had no cases of trichiasis and Queensland had no screening.
- The proportion of First Nations people aged 40 years and over with trichiasis fell from 1.6% in 2011 to 0.1% in 2022.
- Among the 3 jurisdictions that undertook screening in 2022, the prevalence of trichiasis in First Nations people was 0.2% in South Australia and 0.2% in Western Australia. In the Northern Territory, no adults aged 40 years and over who were screened were found to have trichiasis.
