Retinitis pigmentosa patient; MM700 and Specvis visual field graphical maps.

A. The results from MM700 were mapped according to a decibel scale where NO indicates a lack of response to the stimulus in predefined locations. B, C and D. Visual field graphical maps obtained with the Specvis application in three subsequent tests. Color scale of the Specvis maps is expressed in dB. The white X marker indicates the location of predefined, assumed blind spot location. Axes intersect at the fixation point with tick marks at 10° intervals. E. Average over three subsequent Specvis tests. F, G and H. Standard deviation (SD), variance (SD2) and standard error of the mean (SEM), respectively, for three subsequent tests.
