Incidence of retinal vein occlusion and its association with mortality - results from the Gutenberg Health Study. Ophthalmology. Published online February 17, 2025. A pilot study of feasibility and for establishing process sequences was conducted between 2005 and 2007

The baseline assessment of the population-based cohort of 15,010 men and women aged 35 to 74 at the time of inclusion started in April 2007 and was completed in March 2012

An interdisciplinary examination protocol was applied, including general, anthropometric, cardiovascular, psychological and ophthalmological tests lasting 5 hours. A computer-assisted interview and questionnaires elucidated the classic psychosocial, environmental, physical activity, nutritional and lifestyle risk factors

Two and a half years after the baseline examination, the participants were contacted for a follow-up investigation by computer-assisted telephone interview, which recorded the end-points, medical history and self-reported medication and lifestyle factors. Five years after the baseline visit, the participants are invited to the study center for a follow-up visit, comprising of repeated measurements with an extended examination protocol lasting nearly 6 hours

A second telephone interview will take place 7.5 years after the baseline visit. Furthermore, a 10-year follow-up of the whole cohort is planned commencing in 2017
