Lessons in retinopathy of prematurity from Shanghai

The third World Retinopathy of Prematurity (ROP) Congress, held in Shanghai in October 2012, showed that international collaborations have already built up from the previous 2 events. The participants learned about ROP from across the world: who it affects and its behavior, and in a way that would not be possible from the literature. Emerging technologies and treatments are set to have a major impact on the identification and treatment of ROP. Undoubtedly, the picture will have changed dramatically by the fourth World ROP Congress in Mexico in 3 years.
