The COPHy EU program, returning to Lisbon in 2020, again will be devoted to evidence-based debates and discussions amongst session moderators, speakers and the audience, all of whom will examine and analyze the most relevant and controversial issues raised during the course of 2019 and 2020 within the field of ophthalmology. This educational Congress will focus on Retina, but will discuss controversies in other related areas of ophthalmology, including neuro-ophthalmology, ocular imaging, and uveitis. The 11th COPHy EU Congress will emphasize issues related to the region in terms of diagnostics, distinctive responses to treatments and typical complications. Many of the Faculty members will be from Portugal and Spain in order to discuss these typical regional problems. We invite you to participate in the 11th COPHy EU Congress in Lisbon.
