WTW, ATA, and STS distances at different meridians.
Fig 2.
Angle to angle (blue lines) and spur to spur (red line) distances measured at the different meridians.
Horizontal white to white was added and shown as orange lines for comparison. Radial axis starts at 5 mm. Diff. means the difference in value between the ATA and the STS.

Pearson correlation coefficient for horizontal white to white (WTW) versus angle to angle (ATA) and spur to spur (STS) measured at different meridians in each refractive group.
All results had a statistical significance (p < 0.05).
