Clinical Trial: A Study to Determine the Location of the Blind Spot and the Macula-disc Centre Distance on a Fundus Photograph
Study Status: Completed
Recruit Status: Completed
Study Type: Observational [Patient Registry]
Official Title: A Study to Develop Both a Novel Method for Evaluating the True Size of a Retinal Object on Fundus Photographs and a New Reaction-time Based Method for Studying the Visual Field on Healthy Volunteers
Brief Summary: The study is aimed to develop a new reaction-time based method for examining the visual field and to study the effect of refractive error on the magnification of a fundus photograph in order to evaluate the true size of a retinal feature.
