Correlation between the SITA Standard 24-2 and SITA Faster 24-2 strategies to assess campimetric damage in patients with Primary Open Angle Glaucoma.

Abstract

INTRODUCTION: An ideal campimetry should ideally test all the intensities in all the locations, however, it has been found that it is not very practical to carry out tests with the different intensities and, sometimes, it is not even possible due to the limitations that they imply in the duration. SITA Standard strategies were used for more than two decades, but still seeking to improve time without losing quality, a new shorter strategy was created again, which they called the FASTER strategy. OBJECTIVE: To determine the correlation between the SITA Standard 24-2 and SITA Faster 24-2 strategies to evaluate the visual field damage in patients with Primary Open Angle Glaucoma. METHODOLOGY: Analytical observational study. RESULTS: 74 visual field analysis results were analyzed using two techniques SITA Standard 24 - 2 and SITA Faster 24 - 2. The test time for the SITA Standard strategy was 379.64 ± 72.75 seconds and for the SITA strategy Faster 170.93 ± 49.17 (p <0.0001), proving a 55% time reduction for the second. The mean deviation, standard deviation and visual field index values ??do not show statistically significant differences between both tests. The Glaucoma Hemifield Test with the calculation of the Cohen's Kappa index gives a value of 0.316 with a 95% confidence interval of (0.098 - 0.534) which indicates that it is statistically significant. DISCUSSION: The overall results indicate that it is possible to replace the SITA Standard 24-2 strategy with the SITA Faster 24-2 strategy. This change will be especially useful to increase the frequency of campimetric examinations. A greater frequency of examinations is important for earlier detection of glaucoma progression and thus improve the therapeutic behaviors that are taken with the patients who come to our service.
