The painting:
Basically the painting tells the viewer that life is controlled by the change of the environment. This change has taken place within thousands of years, yet man within an eye blink can cause the same change in the land for the sake of development.
The artist:
My mother is fifth generation Australian of European descent and my father a Torres Strait Islander. I grew up knowing I was an Islander but had no knowledge of my family or culture.

What is known about the eye health of Indigenous Australians?
The eye health of Indigenous people before non-Indigenous
people came to Australia was probably very good [1].
In fact, it is believed that the vision of Indigenous people
was better than that of non-Indigenous people [2].
Today, however, it is likely that the eye health of Indigenous
people is not as good as that of non-Indigenous people. The
level of blindness among Indigenous people appears to be higher
than that among non-Indigenous people, with some eye problems
much more common among Indigenous people than among non-Indigenous
people [2, 3].
Importantly, Indigenous people are less likely than non-Indigenous people to receive appropriate levels of eye health services and treatment [4] as should be expected in a prosperous country like Australia.
What are the main types of eye conditions that affect Indigenous people?
The main conditions affecting the eye health of Indigenous people are:
- blindness
- eye focussing problems (refractive error)
- eye problems caused by diabetes (diabetic retinopathy)
- cataracts
- Infections, including trachoma and gonococcal conjunctivitis
(For details of each of these conditions, see What
is known about eye health?)
Information about how these conditions affect Indigenous people
is provided in the following sections.
What is known about blindness among Indigenous people?
A report on Indigenous eye health in 1997 reported that
blindness occurred up to 10 times more often in the Indigenous
population than in the non-Indigenous population [2].
For Indigenous people blindness was mainly caused by cataracts
or damage to the eyes from trachoma.
A major national survey of more than 10,000 Indigenous people
in 2004-2005 found that:
- about one in three people living in non-remote areas, and about one in four people living in remote areas, reported eye or sight problems;
- blindness was around one-and-a-half times more common
for Indigenous than for non-Indigenous people.
[3].
What is known about eye focussing problems (refractive error) among Indigenous people?
The major national survey of more than 10,000 Indigenous people in 2004-2005 found that:
- about one in six people were long sighted - needed glasses to see close objects and
- about one in ten people were short-sighted - needed glasses to see far objects [3].
The main issues for Indigenous people with eye focussing problems are:
- being able to have their eyes tested; and
- the cost and repair of glasses [4].
This is largely because Indigenous people often didn’t use mainstream government schemes that provided low-cost glasses [2]. (Low-cost glasses for looking at close objects, which can be bought from community or town stores, are fine to use and do not do any harm.)
The Nganampa Health Council, which provides health services to people in the AP lands of north-western South Australia, makes low-cost glasses available through community stores [4]. These are popular, even after improved access to subsidised, prescription (specially-made) glasses had been organised. The Council covers the ‘gap’ payment between the price and the state subsidy for one pair of prescription spectacles per person per year – if these are broken or lost many people turn to the ready-made store spectacles.
What is known about eye problems caused by diabetes (diabetic retinopathy)?
Many Indigenous people have diabetes, which can cause an
eye problem called diabetic retinopathy and can lead to blindness,
as well as a number of other health problems.
There is not much information available about diabetic retinopathy
in the Indigenous population, but a study in the Katherine
region of the Northern Territory in 1993 and 1996 found that
that about one in five Indigenous people with diabetes had
eye problems due to diabetic retinopathy [5].
About one in twelve Indigenous people with diabetes were at
risk of losing their eyesight, which is a rate similar to
that of non-Indigenous people with diabetes.
A study of over 1,500 Indigenous adults living in remote SA
between 1999 and 2004 included over 700 people with diabetes,
one in five of whom had signs of diabetic retinopathy [6].
One in twelve of those with diabetic retinopathy had leakage
of blood vessels on the central part of the retina, the macula,
which is responsible for reading and fine detail vision.
There are a number of relatively simple ways to screen for
diabetic retinopathy [7]. Screening with
special cameras has been carried out successfully in a number
of Indigenous settings.
People with diabetes should have their eyes checked every
year, unless they already have diabetes related
eye problems in which case they should have their eyes checked
more often.
With the high and increasing levels of diabetes among Indigenous
people, it is likely that blindness from diabetic retinopathy
will become more common among Indigenous people unless the
level of screening and treatment increases [8].
What is known about cataract among Indigenous people?
According to the major national survey of more than 10,000
Indigenous people in 2004-2005 cataracts were around one-and-a-half
times more common among Indigenous people than among non-Indigenous
people [3]. Cataract was reported more frequently
by Indigenous females (3 in 100 females) than by Indigenous
males (1 in 100 males).
The level of cataract among Indigenous people is slightly
higher among Indigenous people than among non-Indigenous people,
but many Indigenous people have quite long delays in having
the surgery that can improve their eyesight [2,
4].
The delays are mainly caused by limited access to the surgery, but delays can also because of:
- lack of understanding of the need for surgery
- language barriers;
- financial cost;
- worries about being in a hospital; and
- being away from family and land [4, 8].
What is known about eye infections among Indigenous people?
Trachoma and gonococcal conjunctivitis are two eye infections affecting Indigenous people more than non-Indigenous people.
Trachoma
Trachoma, which has been a major cause of blindness among Indigenous people, is still quite common in some communities in northern and central Australia. Recent evidence about trachoma among Indigenous people includes:
- more than one-third of children up to 10 years of age
living in the Katherine region of the NT in the 1990s had
trachoma [5].
- trachoma was found in more than one-half of the children
surveyed in the Pilbara region in 1996 [1]
and one in seven schoolchildren aged 5 to 16 years in the
Kimberley region in 2000 (Trachoma doesn’t occur as
often as it used to in wealthier regions like Broome, Derby
and Kununurra [9].
- less than one in four of more than 800 children aged 4-15 years living in East Arnhem Land in 2002 were found to have trachoma [10].
The drop in recent years in the number of people affected by trachoma In the Anangu Pitjantjatjara lands of SA is thought to be due to improvements in social and economic conditions, community development and increased access to medical care [9].
Trachoma was found to be more common in the wet season than in the dry season among preschool and school-aged children living in two communities in the west Kimberley region of WA [11].
Trachoma control programs are based on the strategy SAFE which stands for Surgery, Antibiotic, Facial cleanliness, Environment (see background info) [4]. In areas where people move from place to place, trachoma control programs need to cover larger areas rather than just a single community.
An antibiotic called azithromycin, an effective treatment for trachoma, is available as a free or subsidised medicine [12].
Nearly all the recent information about trachoma among Indigenous people relates to the infectious stages, when the disease can pass from person to person. There is little information about Indigenous people suffering the later effects of trachoma, where scars can be formed or eyelashes turn in causing damage to the eye, but the following studies give some details:
- more than one-half of the 200 adults attending eye clinics
in Indigenous communities in remote central Australia in
2003 had scarring from trachoma [13].
- 17 of the nearly six hundred Indigenous people aged 50
years or over screened in the Kimberley region of WA in
1998 were found to have eyelashes damaged by trachoma [14].
- a study in 1990 of over 1,500 people living in the Anangu Pitjantjatjara lands of SA found that more than one in four, mainly older people, had signs of the later stages of trachoma (such as scarring and in-turned eyelashes) [15].
Gonococcal conjunctivitis
There have been several outbreaks of gonococcal conjunctivitis in Indigenous populations in central Australia [16]. (See What is known about eye health?, for details about gonococcal conjunctivitis.) A large outbreak occurred in 1997 when nearly 500 people were affected. It is important to monitor the situation and use laboratory tests to confirm cases when outbreaks occur.
Why is the use of eye health services less among Indigenous people than among non-Indigenous people?
The use of eye services is less among Indigenous people
than among non-Indigenous people for a variety of reasons.
This is partly because many more Indigenous people than non-Indigenous
people live in rural and remote parts of Australia, where
specialist eye health services – by ophthalmologists
(eye doctor) and optometrists (another type of health care
professional specialising in eye health) – are less
accessible than in major urban and regional centres.
As well as the lack of services where many Indigenous people
live, other factors contributing to their lower use of eye
health services include:
- financial aspects
- limited transport
- cultural and language barriers;
- lack of culturally appropriate services
- lack of understanding of the need for screening and surgery;
- worries about being away from family and land and of
hospitals.
