title: [Comparison of thickness values in nine macular subfields using time-domain and spectral-domain optical coherence tomography].
abstract: OBJECTIVE
  To compare macular thickness measurements with spectral-domain (Cirrus HD-OCT) and time-domain (StratusOCT) optical coherence tomography.
  
  
  METHODS
  Macular thickness was measured in nine ETDRS subfields in the same eye of 20 healthy subjects using both instruments. Using Cirrus HD-OCT both the Macular Cube 512×128 and Macular Cube 200×200 protocol, using StratusOCT the Fast Macular Thickness Map protocol was performed. Reproducibility of all three measurement series was assessed and the average of the measurement series was compared on each field.
  
  
  RESULTS
  Measurement values obtained by StratusOCT were significantly lower than those obtained by Cirrus HD-OCT (p<0.001) in all subfields. Correlation coefficient between the results obtained by the two protocols of Cirrus HD-OCT was 0.977.
  
  
  CONCLUSIONS
  By using Cirrus HD-OCT we could observe better repeatability than with StratusOCT. Using Cirrus HD-OCT significantly higher measurement values could be obtained in all subfields than those measured with Stratus. Using different OCT instruments we get significantly different values, therefore care needs to be taken when comparing data.
