Correlation between mean ROPtool and human-expert rankings of optical coherence tomography–generated retinal vessel maps for tortuosity and/or dilation. Correlation was strong (r = 0.87) for tortuosity rankings (A), moderate (r = 0.47) for dilation rankings (B), and strong (r = 0.86) for combined tortuosity/dilation rankings (C). Correlation of ROPtool combined tortuosity/dilation rankings and human-expert rankings with clinical examination diagnosis (D). r, Pearson correlation coefficient.
