title: [Pattern reversal visual evoked potentials analysis in patients with noninsulin-dependent diabetes mellitus].
abstract: OBJECTIVE
  To explore the alteration of pattern reversal visual evoked potentials (PVEPs) in patients with noninsulin-dependent diabetes mellitus (NIDDM) and its values in clinical application.
  
  
  METHODS
  PVEPs were recorded in 30 cases with NIDDM and 30 cases of normal individuals.
  
  
  RESULTS
  The abnormal rate of PVEPs in patients with NIDDM was 58.33%, and the latency of P100 was markedly prolonged. The wave-forms were poor-differentiated, and the amplitudes of waves were low.
  
  
  CONCLUSIONS
  Abnormal PVEPs can be regarded as one of the index of visual function in patients with NIDDM. The abnormality of PVEPs is related to blood sugar in empty stomach, course of NIDDM. peripheral nerve lesions and diabetic retinopathy.
