A tooth-enamel protein is found in eyes with a common form of macular degeneration
The finding could point to a new target in treating the ‘dry’ form of the disorder

In an eye with dry age-related macular degeneration, researchers found clumps of hydroxyapatite (pink), a type of mineralized calcium found in tooth enamel, and a protein called amelotin (green) that appears to be involved in producing the deposits.
