Area of visual field and colour discrimination combined as a predictor of chronic open-angle glaucoma.
Area of visual field and colour discrimination were assessed in 167 eyes with ocular hypertension (from 100 women and 67 men with a mean age of 59.8 +/- 11.3 years). The patients were then followed for 3 years. During the follow-up period chronic open-angle glaucoma was diagnosed in 8 (8%) of the 100 eyes with a normal visual field and normal colour discrimination, 7 (14%) of the 50 eyes with a subnormal visual field or subnormal colour discrimination, and 17 (100%) of the 17 eyes with both a subnormal visual field and subnormal colour discrimination, a total of 32 eyes (19%). Our results suggest that chronic open-angle glaucoma develops early in ocular hypertensive eyes in which both the visual field and colour discrimination are subnormal. Glaucoma may not develop at all in eyes with normal values.
