Research design for longitudinal data analysis. The superior-inferior asymmetry in the rate of visual field (VF) loss of eyes starting at different stages of severity and sequences with different number of visits. GEE = generalized estimating equation; MD = mean deviation.

4. Figure 3
Region-wise and point-wise asymmetric patterns of visual field (VF) loss. A–C, The region-wise asymmetric patterns of VF loss of the eyes with primary open-angle glaucoma (POAG) in the early, moderate, and advanced stages, respectively. Dark regions indicate significant superior-inferior asymmetry; regional total deviation (TD) values in the superior hemifield were significantly worse than their counterpart in the inferior hemifield (P ≤ 0.05). D–F, The point-wise asymmetric patterns of VF loss of the eyes with POAG in the early, moderate, and advanced stages, respectively. Dark points indicate significant superior-inferior asymmetry; TD values of the points in the superior hemifield were significantly worse than their counterpart in the inferior hemifield (P ≤ 0.05).

5. Figure 4
Point-wise asymmetric rate of visual field (VF) loss of the eyes with primary open-angle glaucoma (POAG). Top and bottom: The point-wise asymmetric rates of VF loss of the eyes with baseline in the early and moderate stages of glaucoma, respectively. Left to right: The number of visits of the VF sequences analyzed: 5 to 15 visits. Dark points indicate significant superior-inferior asymmetry; rate of VF loss in the test point in the superior hemifield was significantly faster than the rate of VF loss in the test point in the inferior hemifield (P ≤ 0.05).
