Doctors may soon be able to detect Alzheimer's in patients' eyes.

Researchers at the Center for Ophthalmic Research at Brigham and Women's Hospital in Boston have developed a series of techniques that track beta amyloid protein in the eye.

Findings were presented this month at the Optical Society of America annual meeting in Tucson, AZ.

A buildup of beta amyloid protein in the brain is a signal of the disease. Many researchers have been trying to find ways to detect the protein elsewhere in the body, including the eye.  In 2003, Dr. Lee Goldstein and his colleagues of the center published work detailing the presence of beta amyloid in the eye.
