High-pass resolution perimetry and light-sense perimetry in open-angle glaucoma.

To determine the correlation between the results obtained with light-sense and ring perimetry in glaucoma, we examined 201 eyes of 107 patients with ocular hypertension or different stages of glaucoma using Octopus 1-2-3 and the Ophthimus ring perimeter. Statistical parameters describing the mean visual field defect ["global defect, GD," or "neural capacity, NC" (Ophthimus)] were significantly correlated (P < 0.0001). Statistical parameters describing the local deviations were significantly correlated as well ["loss of variance, LV" (Octopus) and "local defect, LD" (Ophthimus), P < 0.0001]. Correlation between the MD and the LV or LD was somewhat less significant. As compared with the MD or LV (Octopus) the Ophthimus parameters GD, NC, and LD were less often pathological. We conclude from our data that due to the good correlation between light-sense and resolution perimetry results, both perimeters are equally suited for the follow-up of glaucoma patients. Sensitivity to early glaucomatous damage seems to be higher in light-sense perimetry (Octopus 1-2-3).
