Purpose: To evaluate the agreement and repeatability of Melbourne Rapid Fields (MRF) 24-2 Rapid visual field testing performed in Natural Viewing Mode using a large projector screen, compared with Humphrey Field Analyzer SITA-Faster (HFA-SFr). Natural Viewing Mode allows patients to view the test at 1 metre wearing only their usual distance correction, removing the need for near-vision correction and reducing perimetry setup time. Method: Thirty-nine patients underwent same-day right-eye visual field testing with HFA-SFr and MRF in Natural Viewing Mode (test order randomised). MRF testing was repeated to assess test-retest repeatability. Agreement between HFA and MRF Test 1 Mean Deviation (MD) and Pattern Deviation (PSD/PD) was assessed. Results: The cohort included 39 patients had a mean age of 66.1 years [rang 30–89]. Diagnoses included 11 normal controls, 1 ocular hypertension, 25 open-angle glaucoma and 2 angle-closure glaucoma. Agreement between HFA-SFr MD and MRF Test 1 MD was excellent, with Intraclass Correlation ICC(2,1)=0.906 [95% Limit of Agreement LoA -4.59, +6.62dB]. Agreement for PD was good, with ICC(2,1)=0.809 [95% LoA -4.66, +5.05dB]. MRF showed excellent test-retest repeatability for MD, with ICC(2,1)=0.983 [95% LoA -2.65, +2.56dB]. False-positive and fixation-loss rates were not significantly different between HFA-SFr and MRF. Test duration was similar between HFA-SFr and MRF (3.0±0.5min). Conclusion: MRF 24-2 Rapid Natural Viewing Mode demonstrated strong agreement with HFA and excellent test-retest repeatability. By eliminating near-correction setup this approach may improve perimetry workflow efficiency with implications for glaucoma screening and ongo
