A protein fragment that litters the brains of people with Alzheimer's disease may also bear responsibility for some of the vision loss in glaucoma, a new study in rats shows.

Some glaucoma patients, however, experience vision loss even with normal eye pressure, indicating that other factors are sometimes involved.
