Ten-year all-cause mortality and its association with vision among Indigenous Australians within central Australia: methodological issues - response

We would like to thank Safari and Ayubi1 for their interest in our recent paper.2 The Central Australia Ocular Health Study, which began in 2005, was the largest epidemiological study of Indigenous Australian ocular health in central Australia since the 1970s. Data collection and analysis for the project yielded important ocular morbidity data for this unique and highly disadvantaged group. Limited funding support meant that only assessments collected between 2005 and 2007 were available for the project which explains why only baseline visual acuity data could be used in the analysis.
