• A five-year follow-up of eyes with elevated intraocular pressures, but without field defects, in which the color vision had been assessed by the 100-Hue test and an anomaloscope was carried out. Field defects developed in eight of 42 eyes with a low 100-Hue score, whereas field defects developed in ten of 13 eyes with a high abnormality in the 100-Hue test score. In the case of the anomaloscope (Pickford Nicholson) scores, field defects developed in four of five eyes with poor yellow-blue scores, whereas similar field defects developed in only nine of 40 eyes with a normal yellow-blue score. With regard to blue-green scores, field defects developed in six of 11 eyes with a poor blue-green score, whereas field defects developed in only seven of 40 eyes with a normal blue-green score. These differences are statistically significant, and the probabilities of an abnormal color vision that results in subsequent field defects have been worked out. The red-green scores were not predictive.
