[Evaluation of static quantitative automated perimetry in the early diagnosis of primary open-angle glaucoma].

The visual field losses in 44 cases (78 eyes) of primary open-angle glaucoma were studied with the Octopus 2000R Static Quantitative Automated Perimeter, revealing the following characteristic changes in the visual field indices: (1) the mean sensitivity (MS) reduced, (2) the mean damage (MD) increased, and (3) the loss variation (LV) or corrected loss variation (CLV) increased. Using the above parameters, not only was the diffuse visual field damage differentiated from the localized, but also the small scotomata due to early visual field damage from localized fluctuations due to scatter or patient incooperation. It was also discovered that the type of field loss correlated with the type of RNFLD.
