OBJECTIVE: To compare the 24-2 and 10-2 visual fields (VFs) and investigate the degree of differences between the 2 tests in glaucomatous eyes with central VF defects. DESIGN: Retrospective study. PARTICIPANTS: In all, 99 eyes of 99 glaucoma patients who underwent both the 24-2 VF and 10-2 VF tests within 6 months were enrolled. METHODS: Glaucomatous eyes with damage involving a central VF defect were divided into 3 groups based on the average total deviation (TD) of 12 central points in the 24-2 VF test. The TD difference was calculated by subtracting the average TD of the 10-2 VF test from the average TD of 12 central points in the 24-2 VF test. The absolute central TD difference in each quadrant was defined as the absolute value of the TD value obtained by subtracting the average TD of 4 central points in the 10-2 VF test from the innermost TD in the 24-2 VF test in each quadrant. RESULTS: The TD differences differed significantly between the severe group and the early and moderate groups ( p < 0.001). In the superonasal quadrant, the absolute central TD difference was significantly greater in the moderate group than in the early group ( p < 0.05). In the superotemporal quadrant, the absolute central TD difference was significantly greater in the severe group than in the other 2 groups ( p < 0.001). CONCLUSIONS: Our results indicate that the results of VF tests for different VFs can be inconsistent, depending on the degree of central defects and the VF quadrant.
