Figures

FIGURE 1
FIGURE 1
The probability of distortion at 2×2 degree intervals across the visual field for six diagnoses. Warmer colors indicate areas where there is a high probability for distortion to occur. The smaller plots to the right of each diagnostic probability map show the upper and lower 95% confidence intervals for the probability estimate at each location.
FIGURE 2
FIGURE 2
Figure 2A. An example of the convex hull and distortions for one eye in an individual with Wet AMD. The dates indicate the time the Amsler was shown to the patient. Figure 2B. The maximum change in area across all pairwise comparisons of all grids within an individual plotted against the corresponding change in time (months) between the two grid assessments. The red line is the best-fit regression line. Each point represents the maximum change in one individual as a function of the time passed between the two grid assessments. Figure 2C. The maximum change in centroid location across all pairwise comparisons of all grids within an individual plotted against the corresponding change in time (months).
