Comparison of the variations in (a) Exx and (b) Eyy in the central quadrants for the AL of control (n = 19), 3-day OHT (n = 11) and 6-week OHT (n = 10), where T, temporal; N, nasal; S, superior; I, inferior. Similar quadrant variations were present for Exx and Eθθ (not shown) among the different groups, but Eyy and Err (not shown) tended to be more homogenous between the four quadrants in 3-day OHT and 6-week OHT. *p < 0.05.
