Acquired color vision changes in glaucoma. Use of 100-hue test and Pickford anomaloscope as predictors of glaucomatous field change
S. M. Drance, R. Lakowski, M. Schulzer and G. R. Douglas
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 years with a
normal yellow-blue scores. 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 the results in subsequent field defects have been
worked out. The red-green scores were not predictive.
