| ABSTRACT: Purpose: To investigate 4 variants of multifocal pupillographic perimetry using a prototype of the TrueField Analyser, which objectively assesses both visual fields concurrently. Methods: We tested 42 normal and 44 glaucoma subjects. Multifocal stimuli of 4 min. duration were presented dichoptically with 24 or 44 regions/eye extending to 30 deg eccentricity. Presentation rates per region were 0.25, 1, or 4 /s. All subjects were also examined with Matrix and HFA perimetry, and Stratus OCT. Results: The 44 region, 1 presentation/s stimuli, gave areas under ROC plots for mild, moderate, and severe fields of 0.743, 0.808, 0.964. Conclusion: Excellent diagnostic accuracy for test durations of 2 min/eye were obtained from this new binocular method. |
