# 5.5 Chiropractic Correlations Panel

![](https://cnri.edu/wp-content/uploads/2026/03/chiro2.jpg)

****Data source****

Spinal segment data is compiled directly into the app (no external asset file is loaded at runtime). The zone-to-segment mapping follows the **pupillary-border research by Velkhover, Liljequist, Felkeconventions**:

| Iris clock position | Spinal region |

|--------------------|---------------|

| 12 o'clock (upper-central) | Upper Cervical C1–C4 |

| 10–11 / 1–2 o'clock (upper) | Mid/Lower Cervical C4–C7 |

| 9 / 3 o'clock (middle) | Upper Thoracic T1–T6 |

| 7–8 / 4–5 o'clock (lower) | Lower Thoracic T7–T12 |

| 6 o'clock (lower-basal) | Lumbar / Sacral L1–S3 |

Both eyes map to the ****same spinal column**** — the spine is midline, so OD and OS findings at the same clock position point to the same vertebral level.
