Reproducibility of segmentation error correction in age-related XXXX : Stratus versus Cirrus OCT.

@entity1 @entity1020 @entity2479
INTRODUCTION: The accuracy of @entity2479 in age-related @entity1020 by optical coherence tomography (OCT) is affected by threshold algorithm line errors. The reproducibility of error correction in Stratus and Cirrus OCT should be examined. METHODS: OCT examinations of a consecutive series of 104 @entity1 with neovascular age-related @entity1020 included in another study were reviewed. 72 eyes exhibited failures in Stratus OCT and 32 eyes in Cirrus OCT and were included in this new study. Algorithm line failures of Stratus OCT (retinal thickness program) and Cirrus OCT (Macular Cube 512 128 program) were corrected independently twice by two ophthalmologists and two residents, respectively, using the Stratus and Cirrus OCT built-in software. Reproducibility was assessed by the interclass correlation coefficient (ICC). RESULTS: The corrected values of central retinal thickness were significantly lower than the automated measured values in Stratus OCT for all examiners (p<0.001), while in Cirrus OCT the differences were not significant (p=0.06-0.09). For Stratus OCT, the ICC for central retinal thickness was 0.991 and 0.997 for the experienced ophthalmologists and 0.89 and 0.97 for the residents. For Cirrus OCT, the ICC was 1.0 and 1.0 for the experienced ophthalmologists and 0.99 and 0.95 for the residents. CONCLUSION: The reproducibility of threshold algorithm line failure correction was good overall in Stratus and Cirrus OCT and can therefore be recommended to improve @entity2479 , particularly when experienced examiners perform the corrections.
