These changes in vision function occur in both diabetic and non-diabetic observers and can be demonstrated psychophysically1 as well as with visually-evoked cortical potentials (VEP's)2.

Many previous studies have reported on changes in multiple vision functions with age (e.g. Häkkinen, 1984, Bergman et al. 1992, Rubin et al., 1995). In most previous studies, the oldest-old are often not well-represented. We are currently in the process of assessing vision function on a large battery of tests in a community dwelling older population living in Marin County, California. The randomly selected population which has been followed longitudinally for other epidemiological studies consists of over 2000 people over the age of 55 year (Reed et al. 1995). The oldest-old are over-represented with 500 participants over the age of 85 in the initial sample. Over 800 participants of the 2000 have participated in the vision study conducted in cooperation with the Buck Center for Research in Aging. The battery includes measure of spatial vision, temporal vision,...

Despite having normal or near normal visual acuity, most individuals showed residual deficits in other vision measures, including reduced color vision, contrast sensitivity, and S and M cone sensitivities. The SKILL Card (Figure 1), proved particularly sensitive, showing all of the 'affected eyes' and most (73%) of the unaffected eyes to be abnormal. In many instances, the loss revealed by the SKILL Card was quite dramatic.
