Diabetic short-wavelength sensitivity: variations with induced changes in blood glucose level.
OBJECTIVE
To investigate variations in diabetic short-wavelength sensitivity with acute, induced changes in blood glucose level.


METHODS
Increment threshold measures were obtained for short-wavelength-sensitive and middle/long-wavelength-sensitive cone pathways after an induced, acute change in blood glucose level in diabetic observers.


RESULTS
Diabetic observers showed an increase in short-wavelength sensitivity, but no change in middle/long-wavelength sensitivity, with a rapid drop in blood glucose level.


CONCLUSIONS
Experimentally induced changes in diabetic blood glucose levels can directly affect diabetic short-wavelength sensitivity.
