Materials and Methods: Visual field tests of a randomly selected eye of 105 glaucoma patients were included in this prospective study. Swedish Interactive Thresholding Algorithm (SITA)-Faster 24-2 and SITA-Faster 24-2C tests were performed on all patients. Test duration, global visual field indices and pattern deviation map results were analyzed.

Results: The SITA-Faster 24-2C test is statistically longer than the SITA-Faster 24-2 test (p=0.014). There was no significant difference in Mean Deviation (MD), Pattern Standard Deviation (PSD), or Visual Field Index (VFI) between the two visual field strategies. There was a statistically significant difference in terms of Glaucoma Hemifield Test (GHT) between the 24-2 grid and 24-2C grid visual field tests (p = 0.0001). Comparing the number of scotomas detected by both test strategies in the 10° central visual field, the 24-2C algorithm detected a significantly higher rate of central scotomas (p=0.017).

Conclusion: Although the 24-2C test was slightly more time-consuming than the 24-2 test, it provided comparable results in terms of global visual field indices and was superior at detecting CVFD.
