title: Rod-cone interaction: some indirect evidence.
abstract: A group of diabetic patients were found to have losses in green-blue colour discrimination and significantly early transition times in dark adaptation. Analysis showed that the green-blue losses were significantly related to early transition time. Pre-receptoral factors cannot account for these results but selective degeneration of the blue cone mechanism can. The results are in agreement with a proposal of rod-blue cone linkage after Trezona (1970).
