| Abstract: | The dark-adapted efectroretinogram (ERG) was investigated in 67 diabetic patients (124 eyes) and in 50 normal subjects (75 eyes). The results showed that the rate of reduced amplitudes and lengthened peak times of a, b waves, as well as the rate of extingaished oscillatory potentials in diabetics ERG were elevated in sequence from no, mild, moderate to severe retinopathy (P<0.01). The rate of reduced amplitudes was higher in eyes with vitreous hemorrhage than those without hemorrhage (P<0.05); and the above stated rate was positively related to the degree of lens opacity (P<0.01). The retina function represented by ERG was greatly related to the severity of diabetic retinopathy, and it was damaged seriously while diabetic retinopathy was severe. It was also found that the amplitudes of a, b waves could be reduced and oscillatory potentials could be extinguished in some diabetic patients without retinopathy. The effects of tens opacity and vitreous hemorrhage upon the results of ERG is also discussed |
