Figure 4.

(A–C) Boxplots showing the difference in the threshold between the groups and eccentricity of contrast discrimination tasks (early processing) and form perception tasks (Intermediate processing), displaying the median with 25th and 75th percentiles. Additionally, error bars extending from the boxes signify the range of variability in the data, and dots within the boxes represent individual thresholds of the participants. Note: The numbers printed near the outlier data points correspond to the participant number, where their age, severity, and duration since diagnosis can be found in Supplementary File 1.
