This document summarizes a webinar for the ONC Ocular Imaging Challenge. The challenge calls for the creation of an app that improves interoperability between ophthalmic devices, measurement tools, and electronic health records. Specifically, the app should convert data from legacy eye devices to standard formats, archive images and data from multiple sources, display images and data, and integrate with EHRs. The top prize is $100,000. Submissions will be judged on criteria such as the breadth of supported devices, usability, workflow integration, and EHR compatibility. The submission period runs from May 14, 2012 to November 9, 2012.
