Vitreous opacities (so-called “eye floaters”) are an increasingly common problem – not only in older, but also in younger patients. In particular, patients with myopia often experience a significant reduction in their quality of life.
The assessment of symptoms caused by vitreous opacities is usually performed using subjective questionnaires. However, there is currently no uniform, standardized tool for classifying and quantifying the visual impairments caused by floaters.
To improve the diagnosis and monitoring of these symptoms, we are providing you with the validated questionnaire from the Floater Intervention Study (FLIES) for download. The placebo-controlled, double-blind FLIES study was conducted in 2021 at the Nutrition Research Centre Ireland (NRCI) – an independent, multidisciplinary research center specializing in studying the effects of nutrition and lifestyle on health.
As part of the study, participants completed the questionnaire before and after a six-month intake of VitroCap®N. The analysis showed that visual disturbances significantly improved in 67% of patients after six months of treatment with VitroCap®N.
The FLIES questionnaire enables a structured assessment of symptoms and can help reliably evaluate individual treatment success. You can download the questionnaire either as a fillable PDF for your patient records or as a print version for hard copies. Page two contains extended patient information. This makes the questionnaire suitable for early completion in the waiting room or for regular monitoring at home.
