A new scoring system for comparing the results of high-pass resolution perimetry and differential light sensitivity...

Using a new standard, we compared the visual field defects detected by high-pass resolution perimetry (HRP) and differential light sensitivity (DLS) perimetry in 61 eyes of 61 open-angle glaucoma patients. Abnormal test points were determined using probability plot analysis of HRP and total deviation probability maps of the Humphrey Field Analyzer. To evaluate the agreement between the two tests, we developed a new scoring system. Thirty-three eyes, 23 eyes, and 5 eyes had good, fair, and poor agreement, respectively. In relation to Aulhorn's stage classification, the more advanced the glaucomatous stage, the more increased the percentages of good agreement. These results suggest that the distribution and severity of visual field defects demonstrated by HRP agree closely with those found using DLS perimetry in glaucomatous eyes, especially those with advanced visual field changes.
