Oscillatory potential and nyctometry in insulin-dependent diabetics.

The study draws a comparison between the oscillatory potential of the electroretinogram and the initial dark-adaptation measured by nyctometry, with the aim of assessing the predictive value of nyctometry in juvenile diabetics. The study included 61 insulin-dependent juvenile diabetics, aged 18-49 years, with a disease duration of more than five years. A statistically highly significant correlation could be demonstrated between alterations in the oscillatory potential and in the initial dark-adaptation. The results justify the assumption that nyctometry can be used as an easily handled clinical tool in selecting those at risk of developing proliferative retinopathy in their subsequent 6-8 years.
