ADDENDUM

After this paper was accepted for publication, the authors were informed of a poster presentation at the Association for Research in Vision and Ophthalmology in 1983 by M. J. Nissen, S. Corkin, J. Growdon, S. Wray and J. Bauer entitled ‘Spatial contrast sensitivity in Alzheimer's disease’. They reported that an unselected group of Alzheimer patients showed spatial frequency contrast sensitivity deficits at all frequencies between 0.5 and 8.0 c/deg. Because their testing procedure was similar to ours, it is not clear what caused the discrepancy between our results and theirs. One possibility is that all our patients had Snellen acuity equivalent to age-matched controls whereas theirs may not have. Since they do not report Snellen acuity in their poster, it is difficult to ascertain whether this is a critical variable. For the moment we still wish to conclude that most Alzheimer patients with normal Snellen acuity also have normal contrast sensitivity functions.
