title: An analysis of the relationship between high-pass resolution perimetry and neuroretinal rim area in normal-tension glaucoma.
abstract: We evaluated the reproducibility of measurements of the visual function index, 'functional channels', of high-pass resolution perimetry and the correlation between functional channels and topographic changes of the optic nerve head, particularly on the neuroretinal rim area. The median coefficient of variation for the six intra-individual measurements of functional channels with high-pass resolution perimetry was 9.5%. In 26 eyes of 18 normal-tension glaucoma patients, functional channels showed statistically significant correlation with the neuroretinal rim area (rim area) of the optic disc measured by a Rodenstock Optic Nerve Head Analyzer. These results suggested that functional channels of high-pass resolution perimetry may be a useful new parameter for evaluating visual function of glaucoma patients.
