Abstract
ABSTRACT
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.
