SIGNIFICANCE: On comparing the Humphrey Field Analyzer (HFA) 24-2C Faster, which tests 10 additional points in the central field, with the 24-2 Swedish Interactive Thresholding Algorithm (SITA) Standard for detecting central field defects, we found that the HFA 24-2C Faster may be used for the initial field evaluation in glaucoma with the advantage of a shorter testing time. PURPOSE: This study aimed to compare the HFA 24-2C Faster with the 24-2 SITA Standard and 10-2 among patients with glaucoma for the number of defective central points, global indices, and testing time. METHODS: Sixty eyes of 60 patients with glaucoma and glaucomatous visual field defects on the 24-2 SITA Standard algorithm underwent the 24-2C Faster and 10-2 field tests. The number of central points detected, global indices, and reliability indices were compared between the 24-2C Faster and the 24-2 SITA Standard and 10-2 field tests. RESULTS: The 24-2C Faster, on average, detected 5.5 defective points more on the total deviation plot and 2 defective points more on the pattern deviation plot than the 24-2 SITA Standard in central 10°. The 10-2 algorithm detected 2.5 times more points on the total deviation plot than the 24-2C Faster. There was excellent consistency by an intraclass correlation coefficient of 0.95 for the mean deviation and 0.93 for the pattern standard deviation between the 24-2C Faster and the 24-2 SITA Standard. There was good consistency by an intraclass correlation coefficient of 0.80 for both mean deviation and pattern standard deviation between the 24-2C Faster and the 10-2. The testing time was significantly lower with the 24-2C Faster compared with the 24-2 SITA Standard and 10-2 test. CONCLUSIONS: Our study demonstrates that the HFA 24-2C Faster may be used for the initial evaluation of the visual field in glaucoma with the added advantage of a shorter testing time compared with the 24-2 SITA Standard program.
