Fig 1.
Inclusion/Exclusion process of the study participants.
The flowchart illustrates the number of identified subjects at the beginning and the number of finally included subjects among the reasons for exclusion. The red boxes represent the subjects with protanopia; the black boxes represent the control group.
Fig 2.
Analysis of the subject with protanopia PRO-06 (A), the subject with normal trichromacy PRO-11 (B) and the subject with protanopia PRO-22 (C), separately for the right (RE) and left eye (LE). The data points are drawn onto a visual field map, showing the loci of the subjects´ stimulus detections. For analytical purposes, the points are superimposed to the boxplots. These boxplots are visualizing the statistical parameters median (middle line) and interquartile range (IQR: 25th and 75th quartile, lateral borders of the box). The individual thresholds of each condition were measured along the horizontal meridian (horizontal lines) by using the Goldmann stimulus characteristics III1e. The RWR was calculated by dividing the extent obtained for the red marks by the extent obtained for the white marks, respectively.
Fig 3.
RWR medians for the right eyes of subjects with protanopia (red points, n = 5) and those with normal trichromacy (grey points, n = 6).
The single data points are superimposed to the boxplots, which are visualizing the median (middle line) and interquartile range (IQR: 25th and 75th quartile, lateral borders of the box). The whiskers represent 1.5 times the interquartile range. The individual thresholds of each condition were measured along the horizontal meridian. The results are plotted separately for the two intensities III4e (left part) and III1e (right part).
Fig 4.
Graphical analysis of the reaction times RT [in seconds] for the subjects with protanopia (red points) and the control group with normal trichromacy (grey points).
Each data point represents the calculated median out of the RT-measurement, repeated three times, for each condition. For description of the boxplot, see legend of Fig 3. The boxplots are shown separately for the intensities III4e and III1e and are additionally labeled for the stimulus color white (black boxes) and red (red boxes).
