Web1 de jan. de 1983 · This difference was reflected in the peripheral/foveal threshold ratios of the two subjects and underlines the necessity of ensuring the stability of thresholds. Stereoacuity measurements were also obtained using several different square separations at the fovea and at 2.5°, 5° and W peripheral locations along the horizontal and vertical … WebHowever, VF 10-2 testing with foveal threshold value may yield more accurate measurement of central visual function and more accurate topographic correspondence with FAZ size than the VF 24-2 test. Since this study demonstrated a significant correlation between FAZ size and fVD and pfVD, we can deduce the vascular status of the macula …
