Comparison between Fundus Automated Perimetry and Humphrey Field Analyzer: performance and usability of the Fundus Automated Perimetry and Humphrey Field Analyzer in healthy, ocular hypertensive, and glaucomatous patients

Purpose: We compared the performance and usability of the Fundus Automated Perimetry (FAP) and Humphrey Field Analyzer (HFA) in patients with glaucoma, ocular hypertension, and healthy subjects. Materials and methods: A total of 60 participants, divided in three groups of 20, glaucoma (POAG), ocular hypertension (OHT), and controls group, underwent a HFA test 24-2 SITA standard and a FAP test 24-2 ZEST sequence, in randomized order. The mean differences between perimeters of mean deviation (MD), pattern standard deviation (PSD) were correlated using the t-test and the Bland–Altman plot while execution time, Glaucoma Staging System 2 (GSS2), Hodapp–Parrish–Anderson staging system, localization of the defect, false positives (FP), and false negatives (FN) were compared with t-test analysis. Usability was measured through answers of a dedicated questionnaire. Results: MD’s difference was higher for FAP than HFA: OHT −2.20 ± 1.33 dB ( p Conclusion: Considering MD and GSS2 classification, FAP finds more severe defects. Moreover, although FAP duration is longer, this method is preferred by most of the patients.
