Cases of RD were identified using a combination of International Classification of Diseases, Ninth revision, Clinical Modification (ICD-9-CM) and ICD-10-AM (Australian modification) diagnosis and procedure codes from routinely collected hospital inpatient data provided by the WA Data Linkage Branch. A Poisson regression model was used to examine the influence of age group, gender, season and year of surgery on RD incidence rates.Main outcome measures Age-standardised and sex-standardised incidence of first-eye RD and incidence rate ratio (IRR) of first-eye RD associated with age, sex and season. Counts of RD repair according to surgical technique.Results There were 4376 first-eye RD between 2000 and 2013. Age-standardised incidence ranged between 12.78 and 16.20 cases per 1 00 000 person-years. After adjusting for age, year and season, males had a higher risk than females for incident detachment (IRR 1.82, 95% CI (CI) 1.71 to 1.93), as did those aged 60–79 years (IRR 33.26, 95% CI 27.60 to 40.08) compared with those aged less than 20 years. RD repair with vitrectomy alone increased by 59% over the study period.Conclusion The incidence of first-eye RD remained stable between 2000 and 2013. The risk was higher in males and with older age.
