A correction (25 Nov., p. 1308) for the caption that accompanied photographs in the article (Research News, 11 Nov., p. 973) about the report by Leonard F. M. Scinto et al. "A potential noninvasive neurobiological test for Alzheimer's disease" (11 Nov., p. 1051), was itself incorrect. The photos showed the undilated and dilated eye of a normal 36-year-old member of the Scinto group, not the undilated and dilated eye of an Alzheimer's patient, as the correction stated. The error was the result of a misunderstanding between Science and the Brigham and Women's Hospital news office, which took the photos. A patient photo was not supplied, Scinto says, because subjects were not then being studied and hospital policy does not permit treatment of a patient, even with dilute eyedrops, for the purpose of taking a photo. As the photo subject was a normal individual, Scinto also notes that the dilation was achieved by a 1% solution of tropicamide (a standard dose), rather than the 0.01% used in the trial. Science regrets the error.
