Before a child with CLN3-Batten disease loses the ability to read a face or cross a room unassisted, something quiet and foundational is already failing deep within the eye. Researchers at the University of Rochester have built a three-dimensional retina from human stem cells to study this rare inherited condition, and what they found reframes the disease entirely: vision is not lost because light-sensing cells fail first, but because the support cells that sustain them collapse, taking everything built upon them down as well. In identifying a specific enzyme deficiency — acid ceramidase — as
