The priority given to vision loss
Like all ophthalmologists, Jackson instinctively knew the importance of good vision and eye health. The treatment of eye disease and the prevention of blindness is our highest priority; it is our calling. As ophthalmologists, we all accept the importance of good vision without question.
In 1980, the World Health Organization (WHO) asked me to review eye services in Pakistan at the request of the Pakistani government. When I presented my report to the Pakistani Minister of Health, he received the
Population-based evidence
Epidemiologic field studies can provide a wide range of information. In ophthalmology, they have given us great information about the prevalence and incidence of eye diseases and disease risk factors. In 1991, there were no coherent data on the magnitude or causes of vision loss in Australia. At best, only fragmented reports were available. To address this gap, the “Melbourne Visual Impairment Project” (VIP) was started. It was a large, population-based survey to determine the prevalence and
The prevalence and causes of vision loss
These various epidemiologic surveys carried out in different countries show a remarkably consistent picture. Even though there may be large differences in ethnic minorities, economic status, and health care delivery in these different developed economies, the age-specific rates and causes of vision loss are remarkably consistent. These studies demonstrated that the amount of vision loss and eye disease increases dramatically with increasing age. For each decade over the age of 40, the amount of
The impact of vision loss
Over the last few years, studies in Australia and in the US have shown that even relatively small degrees of visual impairment can have a major impact on the quality and length of life. The critical level of vision is that level usually required for an unrestricted driving license. People with less than 20/40 vision have a significantly increased risk of falls,28, 29 hip fractures,30, 31 and depression.32, 33 They have a substantial loss of social independence,34, 35 and they are likely to be
The costs of vision loss
More recently, we have analyzed the economic impact and cost of vision loss in Australian communities.37, 38 We found that vision loss and its costs had been totally overlooked.
Throughout the following analyses I have used Australian dollars. The exchange rate is usually AU $1.00 to between US $0.70 to US $0.75. International dollars have been introduced to give a comparison of the relative Purchasing Power Parity of a currency in its own country, sometimes called the “Big Mac Index”.39 In
The costs of eye care
Most blindness and vision loss now can be prevented or treated, usually by highly cost-effective measures. You will remember that WHO considers an intervention to be cost-effective if it costs less than three times GDP per capita to avert one lost Quality Adjusted Life Year or QALY (an economic measure of a year of good health).45 In Australia, this threshold is set at less than $112,000 per QALY . However, if an intervention costs less than one GDP per capita, $37,000 per QALY, then is very
Dollars and sense
At long last, armed with this information, we now are able to discuss priorities with health bureaucrats and policy makers, and Ministers of Health, in a way we could not do in the past. We now have the information that is required to place the needs for eye care in perspective and to compare it with other health priorities. We can quantify and rank the impact of vision loss and of even more importance, the cost of not addressing it.
In November 2005, the Australian governments released a
