Summary
Cataract is a major cause of correctable visual loss with surgery the only treatment available. Cataract surgery is now one of the most commonly performed operations. With the ageing population, the number of operations is set to double within the next 12 years in Western Australia, from 10,000 procedures a year currently. Although surgery is successful in most cases, complications do occur.

Cataract surgery is now one of the most commonly performed operations. With the ageing population, the number of operations is set to double within the next 12 years in Western Australia, from 10,000 procedures a year currently. Although surgery is successful in most cases, complications do occur. Endophthalmitis (infection of internal structures of the eye), incomplete cataract removal, detachment of the retina and corneal decompensation (opacity of the clear front of the eye) are four major complications of cataract surgery. These complications may cause blindness and are expensive to treat. We propose to investigate these serious, potentially blinding, complications of cataract surgery by measuring how often these complications occur and to examine if changes in surgical technique over the past 20 years have resulted in better outcomes. We will also evaluate risk factors for endophthalmitis; and determine the quality of life and economic costs of endophthalmitis after cataract surgery. Our study findings will enable us to better inform eye surgeons, the general community, health policy makers and the scientific community about the cost versus safety of different forms of cataract surgery. Unless effective strategies can be found to reduce the rate of complications, the personal and community burden of these devastating complications will only increase as the number of operations continues to increase.Read moreRead less
ENDOPHTHALMITIS IN WESTERN AUSTRALIA (1980-2002): INCIDENCE, MANAGEMENT AND EFFECTIVENESS OF CHEMOPROPHYLAXIS

Summary
Endophthalmitis is a serious sight threatening infection of the internal cavities of the eye. Although endophthalmitis is not a common post-operative complication of eye surgery, 200 cases of this serious sight threatening infection occur each year in Australia following cataract surgery. Not only is this condition extremely distressing to the patients and surgeons alike, around A$4 million per year is spent each year treating the infection. Also, there is significant expenditure on methods to p ....Endophthalmitis is a serious sight threatening infection of the internal cavities of the eye. Although endophthalmitis is not a common post-operative complication of eye surgery, 200 cases of this serious sight threatening infection occur each year in Australia following cataract surgery. Not only is this condition extremely distressing to the patients and surgeons alike, around A$4 million per year is spent each year treating the infection. Also, there is significant expenditure on methods to prevent the infection that have not, as yet, been demonstrated beneficial. Our study will use a multidisciplinary team consisting of consultant ophthalmologists, public health researchers, a biostatistician and health economist to assess the impact of endophthalmitis in WA from 1980-2002 (around 480 cases). The population-based WA Linked Database provides a unique opportunity to produce what will be the largest population study of endophthalmitis. Data from the study will provide important information to develop best-practice treatment guidelines to prevent endophthalmitis following cataract surgery. The significance of this study will be that accurate information on the clinical epidemiology and true cost of endophthalmitis will be obtained for WA. By studying the records of patients with endophthalmitis and comparing them with matched patients, who did not have post-operative endophthalmitis following cataract surgery, we will characterise the risks for this severe complication by identifying the underlying factors that are responsible for the infection. We will also better understand the effect of methods used to prevent the infection. The use of a whole population-based study to assess methods of endophthalmitis prevention has not been done before and will have a significant beneficial impact on health policy and best-practice, not only in Australia, but also internationally.Read moreRead less
Metabolic Syndrome, Inflammation And Non-alcoholic Fatty Liver Disease In Busselton

Summary
The metabolic syndrome is a clustering of obesity, insulin resistance, high cholesterol and high blood pressure. It could affect up to 30% of the population and often leads to diabetes and heart disease. Fatty liver disease is a chronic liver condition that often has no symptoms but can lead to serious liver damage. It could affect up to 25% of the population and is common even in people who drink very little alcohol. The rising prevalence of obesity in Australia suggests that the metabolic synd ....The metabolic syndrome is a clustering of obesity, insulin resistance, high cholesterol and high blood pressure. It could affect up to 30% of the population and often leads to diabetes and heart disease. Fatty liver disease is a chronic liver condition that often has no symptoms but can lead to serious liver damage. It could affect up to 25% of the population and is common even in people who drink very little alcohol. The rising prevalence of obesity in Australia suggests that the metabolic syndrome and fatty liver disease may be on the increase and therefore so too could diabetes and heart disease which already consume significant health resources. Using the unique health data collection of the Busselton Health Study in Western Australia, this project will help to determine how common these conditions are in Australia and lead to a better understanding of the nature and causes of these conditions including the possible role of chronic inflammation. This important information will be used to provide opportunities for better risk assessment, disease prevention, and earlier intervention.Read moreRead less

Summary
This project concerns operations to unblock or bypass the coronary arteries that supply the muscle of the heart. The project has two parts. One is concerned with checking that changes in medical and surgical treatment of coronary artery disease have been followed by improvements in survival of affected patients.

The project has two parts. One is concerned with checking that changes in medical and surgical treatment of coronary artery disease have been followed by improvements in survival of affected patients. The second will use data on changes in the Australian population, changes in the frequency of heart disease and changes in treatments for heart disease to predict how many coronary operations will be needed in Australia over the next decade. This is a vital step in planning hospital services for patients with coronary disease.Read moreRead less
