Abstract
Recently, several laboratories have introduced chromatic adaptation techniques to automated perimetry in an effort to isolate the activity of short-wavelength-sensitive (SWS) mechanisms. 1-6 In particular, short-wavelength sensitivity losses in the visual field have been reported to be more prevalent than deficits obtained with standard perimetry in ocular hypertensives and patients with early glaucomatous damage. 1-4 In addition, we have found that short wavelength sensitivity losses appear to have both diffuse and localized components, 1,3 that short wavelength sensitivity defects are generally larger in area than those found with standard automated perimetry,3 that there is partial but not complete overlap between short wavelength sensitivity losses and visual field defects with standard perimetry,3 and that short wavelength sensitivity losses in ocular hypertension and glaucoma display nerve fiber bundle patterns. 4 These results indicate that short wavelength sensitivity losses may be an early indicator of glaucomatous damage.
