Methods
This was a cross-sectional, prospective study. The study protocol was approved by the Ethics Committee of the Pontificia Universidade Católica do Paraná and an informed consent was signed by all participants. All research adhered to the tenets of the Declaration of Helsinki. All subjects underwent a complete ophthalmological examination, including best-corrected visual acuity measurement, slit-lamp biomicroscopy, applanation tonometry, optic disc evaluation with a 78-diopter lens, and OCT for
Results
Among the 74 subjects included in the study, 55 (74%) were female and 65 (88%) were White. The mean age was 40.9 ± 12.1 years, ranging from 21.8 to 74.6 years. All participants had at least a high school degree and 35 (47%) had at least a graduate degree. Table 1 compares test duration, false-positive responses, number of unreliable exams, foveal threshold, MD, VFI, PSD, GHT, and number of points depressed at P < 5%, P < 2%, P < 1%, and P < 0.5% on the total deviation and pattern deviation
Discussion
SAP offers a standardized and efficient method to evaluate the hill of vision and has been employed for decades to diagnose and monitor functional glaucomatous damage.3,4 However, as a subjective test, it is affected by external factors, including visual fatigue.5,6 To overcome the influence of visual fatigue on the information provided by SAP, strategies have been developed to reduce test time. The SFR represents the latest development in this direction.12 However, before replacing SS with
