title: Pattern reversal visual evoked potentials in eyes with macular holes and their fellow eyes.
abstract: OBJECTIVE
  To investigate whether the pattern reversal visual evoked potential can be useful in the diagnosis and management of macular hole patients.
  
  
  METHODS
  The pattern reversal visual evoked potential was measured in 66 patients with a macular hole and in 43 healthy control subjects. Check sizes of 34', 17' and 10' were applied.
  
  
  RESULTS
  Results showed that, for the check sizes of 34', 17' and 10', eyes with a macular hole had significantly prolonged N80 and P100 latencies and a significantly reduced P100 amplitude as compared to their fellow eyes. Furthermore, for the 10' check size, the fellow eyes appeared to have a significantly reduced P100 amplitude in comparison with the control eyes, whereas N80 and P100 latencies of the fellow eyes of the macular hole patients were not prolonged.
  
  
  CONCLUSIONS
  Significant pattern reversal visual evoked potential alterations were shown in eyes with macular holes and fellow eyes for small check sizes.
