    Example of automated segmentation errors resulting in an underestimation of <t>RNFL</t> thickness values. (Top) The circumpapillary <t>OCT</t> B-scan acquired at baseline is shown with automated segmentation of the anterior RNFL boundary in yellow and posterior RNFL boundary in red. There are two errors along the posterior boundary segmentation; one occurs at the crossing of the superior branch artery and vein (red arrows), resulting in RNFL thickness values that are 15–20% smaller than those for manually refined segmentations in sectors 3 and 4. The second error (red arrowhead) occurs at a vessel crossing in sector 9 (nasal inferior), resulting in values that are 10–15% below the manually refined values. A magnified view of the first error at baseline (inset) is shown persisting over time to the 4-year follow-up visit. (Bottom) The same scans are shown with manually refined segmentations.

    Example of automated segmentation errors resulting in an underestimation of RNFL thickness values. (Top) The circumpapillary OCT B-scan acquired at baseline is shown with automated segmentation of the anterior RNFL boundary in yellow and posterior RNFL boundary in red. There are two errors along the posterior boundary segmentation; one occurs at the crossing of the superior branch artery and vein (red arrows), resulting in RNFL thickness values that are 15–20% smaller than those for manually refined segmentations in sectors 3 and 4. The second error (red arrowhead) occurs at a vessel crossing in sector 9 (nasal inferior), resulting in values that are 10–15% below the manually refined values. A magnified view of the first error at baseline (inset) is shown persisting over time to the 4-year follow-up visit. (Bottom) The same scans are shown with manually refined segmentations.
