title: Comparison of StratusOCT and Cirrus HD-OCT imaging in macular diseases.
abstract: OBJECTIVE
  The Cirrus HD-OCT (Carl Zeiss Meditec, Dublin, CA) device is a spectral-domain optical coherence tomography system that allows faster data acquisition than the previous generation StratusOCT (Carl Zeiss Meditec, Dublin, CA), which is a time-domain device. The authors compared images from both units to determine the clinical usefulness of spectral-domain optical coherence tomography technology in patients with macular diseases.
  
  
  METHODS
  Six consecutive patients were imaged with both the Cirrus HD-OCT and the StratusOCT devices and the images were compared.
  
  
  RESULTS
  Cirrus HD-OCT images were typically more useful than StratusOCT images for assessing fine architectural details in macular pathology. The Cirrus HD-OCT software also facilitated a better understanding of three-dimensional data volumes.
  
  
  CONCLUSIONS
  Commercially available spectral-domain optical coherence tomography is a clinically useful tool for visualizing and understanding macular diseases and offers benefits not inherent in previous generation machines.
