Perimetric thresholds of normal and red-green-deficient persons were measured using three colored test stimuli and a low-intensity white background. Meridians of 45°, 135°, 225° and 315° were tested within 30° peripherally. A statistically significant sensitivity difference between the quadrants was found at eccentricities of 5–30° from the center with the highest sensitivity in the lower temporal field and the lowest one in the upper nasal field, this difference being slightly larger when tested with red (615 nm) or violet (443 nm) light compared with blue-green (497 nm) test light. No difference in the field quadrant sensitivity was observed between the results of the series of normal and red-green-deficient persons.
