New imaging approach simplifies retina exams by enabling digital refocusing
September 10, 2025
A team of researchers from Johns Hopkins University, Boston University, and collaborators has now demonstrated a new type of fundus camera that removes one of the main challenges: focusing. Instead of relying on mechanical adjustments of a lens, the system uses a special diffuser that captures 3D light information during imaging. With this data, a computer can reconstruct and refocus images after they are taken.
