PURPOSE: To describe a tangent perimeter developed on an Apple iPad (Melbourne Rapid Field, MRF). METHODS: -test and repeatability returned from Bland-Altman analysis. RESULTS: < 0.05). Simulated defects with a mean defect (MD) of -3.3 dB are detected by the MRF. The Coefficient of repeatability was 9.6% (SD ∼2.9 dB) in normal regions and 48.1% (SD ∼8.0 dB) in areas of simulated scotoma. CONCLUSIONS: Tablet technology can return efficient and reliable thresholds to 30° as a tangent perimeter. TRANSLATIONAL RELEVANCE: The MRF will allow testing at a bedside, at home, in rural or remote areas, or where equipment cannot be financed.
