Figure 6.

Two examples of the primary stimulus locations (diamond symbols) for the sinusoidal stimulus that we selected to target the glaucomatous damage to the RNFL. The black diamonds indicate that contrast sensitivities to the oriented stimuli were below the 95% reference range and the white diamonds indicate that contrast sensitivity was not below the reference range. These two patients (patients 3 and 4) responded at all but a few locations using the suprathreshold strategy (see Fig. 3, third and fourth rows), yet had abnormal contrast sensitivity for the sinusoidal stimulus at similar locations.
