The purpose of this review was to compare the prevalence of diabetic retinopathy (DR) between Indigenous and non-Indigenous Australians with Diabetes Mellitus (DM) using all available reported data, in order to help direct further research to those most susceptible to severe outcomes. All published studies describing prevalence of DR in a defined study population within Australia published between 1985 and 2013 were identified. Potentially relevant studies were reviewed and the following published data was extracted: study design, sample size with self-reported DM, indigenous status, mean age and range, gender, mean duration of DM, prevalence and severity of DR, and method used to grade DR. Six Indigenous studies (2865 persons with DM) and 5 non-Indigenous studies (9801 persons with DM) reporting DR prevalence satisfied inclusion criteria. Estimated prevalence of any DR among Indigenous Australians with DM was 23.4% compared with 28.9% for non-Indigenous Australians (χ 2
