title: Correlation between ERG oscillatory potential and psychophysical contrast sensitivity in diabetes.
abstract: Correlation between the electroretinographic oscillatory potential and psychophysical contrast sensitivity function was examined in patients with different stages of diabetic retinopathy. Contrast sensitivity function was evaluated by Arden's grating test. The amplitude of the oscillatory potential was significantly reduced in cases with low contrast sensitivity (P less than 0.01).
