BACKGROUND AND OBJECTIVE: To map retinal sensitivity values within glaucomatous visual field defects (VFD) to corresponding values of scanning laser polarimetry (SLP) of the peripapillary retinal nerve fiber layer using the Wirtschafter disc sector classification.
METHODS: Eyes with glaucomatous VFD (N = 28) underwent SLP and Humphrey automated perimetry. The Wirtschafter disc sector classification was used to obtain SLP values corresponding to VFD. The average and modulated SLP values were calculated and correlated with VFD.
RESULTS: No significant correlation was found between retinal sensitivity and the Wirtschafter disc sector SLP values, using average values (P =.904) or modulated values (P =.409).
CONCLUSION: Despite use of modulation parameters customized to correspond with the Wirtschafter disc sector classification, topographic mapping of retinal sensitivity levels within glaucomatous VFD to corresponding SLP values was not possible in this group of glaucomatous eyes.
