Résumé
To investigate the variability in optical coherence tomography angiography (OCTA) image interpretation in a cohort of retina specialists. A survey consisting of a study set of images from 12 eyes examined by OCTA was created. Eight multiple-choice answers were provided as response options for each case. The survey was sent to 100 retina specialists, with instructions to complete the survey only if they had facility with the interpretation of OCTA images. Thirty-eight physicians completed the survey. Data generated were subsequently analyzed and interpreted. Krippendorff's alpha coefficients of agreement and their associated 95% confidence intervals (CIs) were utilized for statistical analyses. For the overall data, the estimated alpha coefficient was 0.366 (95% CI, 0.31-0.47). Although the estimated alpha coefficient is significant, the level of significance is considered low, as it is far from unity (0.366). Therefore, although statistically significant, the overall data did not demonstrate either high reliability or agreement in interpretation. Additional analyses evaluating the influence of years and location of practice, and frequency of OCTA use did not demonstrate a significant effect on reliability measures. Significant variability exists in the interpretation of OCTA images in this cohort of retina specialists. The overall data did not demonstrate high reliability or agreement in interpretation of images, suggesting the need for additional study of this nascent technology.

BACKGROUND AND OBJECTIVE
To investigate the variability in optical coherence tomography angiography (OCTA) image interpretation in a cohort of retina specialists.
PATIENTS AND METHODS
A survey consisting of a study set of images from 12 eyes examined by OCTA was created. Eight multiple-choice answers were provided as response options for each case. The survey was sent to 100 retina specialists, with instructions to complete the survey only if they had facility with the interpretation of OCTA images. Thirty-eight physicians completed the survey. Data generated were subsequently analyzed and interpreted.
RESULTS
Krippendorff's alpha coefficients of agreement and their associated 95% confidence intervals (CIs) were utilized for statistical analyses. For the overall data, the estimated alpha coefficient was 0.366 (95% CI, 0.31-0.47). Although the estimated alpha coefficient is significant, the level of significance is considered low, as it is far from unity (0.366). Therefore, although statistically significant, the overall data did not demonstrate either high reliability or agreement in interpretation. Additional analyses evaluating the influence of years and location of practice, and frequency of OCTA use did not demonstrate a significant effect on reliability measures.
CONCLUSIONS
Significant variability exists in the interpretation of OCTA images in this cohort of retina specialists. The overall data did not demonstrate high reliability or agreement in interpretation of images, suggesting the need for additional study of this nascent technology.
