Variability and Sensitivity of Short-Wavelength Color Visual Fields in Normal and Glaucoma Eyes

It has been shown that color visual fields 1) differentiate between normal and glaucomatous eyes; 1 - 4 2) show deficits in many suspect eyes when standard fields remain normal; 3 3) indicate more extensive damage across the retina than evidenced by standard visual fields; 4) show progressive loss sooner than standard fields in many eyes with primary open angle glaucoma; 5 and 5) can identify early functional loss in suspect eyes at greatest risk for glaucoma. 6 These results suggest that color visual field testing may be a useful clinical test for assessing functional damage in ocular hypertension and primary open angle glaucoma. However, its clinical utility depends in large part on its ability to reliably detect glaucoma in a patient population.
