AbstractBACKGROUND: To determine the prevalence and severity of diabetic eye disease among adults aged >/=40 years with unrecognized diabetes in Fiji. DESIGN: Population-based cross-sectional survey using multistage cluster random sampling. PARTICIPANTS: 1381 (=73.0% participation). METHODS: Interview-based questionnaire; visual acuity measured; dilated ocular examination performed; glycosylated haemoglobin (HbA1c) concentration determined. MAIN OUTCOME MEASURES: Prevalence and grade of diabetic retinopathy/maculopathy. RESULTS: Sample prevalence of diabetes was 44.8% (95%CI 42.2-47.5%), with 63.4% (95%CI 59.5-67.1%) previously undiagnosed (384/606). Predictors of undiagnosed compared with previously diagnosed diabetes were female gender (P = 0.001), rural residence (P = 0.049) and not having a relative with known diabetes (P 50 years), this was vision-threatening (1.0%; 95%CI 0.3-2.8). Mean HbA1c (10.7 +/- 2.6%) of participants undiagnosed and with diabetes eye disease was higher (P
