Abstract Purpose: To compare the effectiveness of the 24-2 and 10-2 SITA Standard (SS) visual field strategies in detecting central defects in patients with early-stage primary open-angle glaucoma (POAG) and glaucoma suspects. Methods: A total of 39 eyes from 20 patients diagnosed with early-stage POAG or suspected glaucoma were included. Each patient underwent both 24-2 and 10-2 SS visual field testing on separate days. Evaluated variables included mean deviation, visual field index, and the presence of central defects. Data were analyzed using descriptive statistics and inferential tests, including the Chi-square test and ANOVA. Results: The 24-2 strategy revealed visual field defects in 61.5% of eyes, with arcuate scotoma being the most frequent (35.9%), followed by nasal step (17.9%) and central defects (2.6%). In contrast, the 10-2 strategy identified central defects in 30.8% of eyes, a significantly higher proportion ( P < 0.05). In addition, 20.5% of eyes showed central defects exclusively in the 10-2 test. Conclusion: The 10-2 strategy demonstrated greater sensitivity for detecting central defects in early-stage POAG and glaucoma suspects. Its incorporation into routine practice may enhance diagnostic precision and optimize clinical monitoring.
