Supplementary Material for: Incidence of Retinal Detachment in Germany: Results from the Gutenberg Health Study

Purpose: To investigate the incidence of retinal detachment in the German population and to assess potential risk factors. Methods: The Gutenberg Health Study is a population-based cohort study in Mainz, Germany, including subjects (n = 15,010) with an age range from 35 to 74 years at baseline examination. Study participants underwent a comprehensive ophthalmological examination including distant-corrected visual acuity, refraction and slit-lamp examination at baseline examination. A computer-assisted telephone interview was conducted after 2.5 and 5 years, and health events were recorded. The 5-year cumulative incidence of retinal detachment was computed for the study sample and stratified on age decades. Risk factors were analyzed using logistic regression including age, sex, spherical equivalent, pseudophakia and prior laser retinal therapy. Results: 13,416 participants (age 52.2 ± 10.7 years, 48.8% female) were included in this analysis. Twenty-eight subjects had a retinal detachment in one eye, no subject had a retinal detachment in both eyes. The 5-year cumulative incidence of retinal detachment was 0.21% (95% CI 0.14–0.31%), the incidence rate was 42/100,000 person-years. Risk factors were male sex (OR 4.16, p = 0.004), pseudophakia (OR 3.93, p = 0.045) and myopia (OR 1.31 per diopter myopia, p < 0.0001), but not prior retinal laser therapy or age. Conclusion: The incidence of retinal detachment in Germany at the age of 35–74 years is comparable to estimates from neighboring European countries. Risk factors are male sex, pseudophakia and myopia.
