Relationship between Δh and % SC collapse in all eyes and eyes with SC collapse. (A) Using all eyes, a significant, negative correlation was observed between Δh (mm) and the percent collapse of SC (R2 = 0.642, n = 40; P < 0.0001). (B) Using only eyes that exhibited SC collapse, a significant, negative correlation was observed between Δh (mm) and the percent collapse of SC (R2 = 0.528, n = 23; P < 0.001).
