Graz, Austria What is the background for this study? What are the main findings?

Response: Knowledge about risk factors and/or pathways involved in pathogenesis is from special importance in order of preventing diseases.

The role of sunlight in several eye diseases is unclear. In our study we found a close relation between sun light exposure – evaluated by a full body skin examination and a personal questionnaire – and iris freckles. Therefore we suggest the presence of iris freckles as a novel biomarker indicating high ocular sun exposure. What should readers take away from your report?

Response: The evaluation of iris freckles might help to understand the role of sunlight in pathogenesis of several eye diseases. What recommendations do you have for future research as a result of this study?

Response: Iris freckles are easy to evaluate – therefore I hope that a broad spectrum of diseases will be evaluated. I am really exited about the upcoming results
