Schematic drawing of a modified Goldmann Overlay Map showing the retinal ganglion cell density in a right eye visual field projection (see Rutkowski and May 2016). a The area measured with an ordinary 60–4 Humphrey visual field adjustment is marked in colour; note that the temporal measurements reach only 60 degree. b The area measured with a 20 degree nasal to the fovea adjustment is marked for the nasal (left) and temporal (right) region; note that now the measurement covers up to 80 degree in the temporal side. c The collage demonstrates the combination of both measurements evaluated
