Title:
VISUAL-FIELD-TEST ASSISTANCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/132470
Kind Code:
A1
Abstract:
[Problem] To provide a visual-field-test assistance device capable of estimating the present condition of a visual field at each test point. [Solution] With a predetermined mixture distribution as a prior distribution, the present invention refers to time series information from visual-field test results obtained in the past from multiple cases to learn parameters related to the predetermined mixture distribution. A visual-field-test assistance device uses a Bayesian inference to calculate an estimated-test-results vector expressing estimated results that are the results of a visual field test for visual sensitivity at each test point, and conducts information output-processing on the basis of the estimated-test-results vector obtained by the Bayesian inference.
