Title:
視野検査装置、その制御方法及び視野検査プログラム
Document Type and Number:
Japanese Patent JP7082889
Kind Code:
B2
Abstract:
A visual field test device includes: first probability density function acquisition unit performs step (1) of obtaining a probability density function f(x1) for a result value x1 obtained in a first visual field test; a stimulation threshold determination unit performs step (2) of setting a stimulation threshold t1 to a value in the range of x1 in the f(x1); a test result acquisition unit performs step (3) of obtaining test results indicating if a result greater than or equal to t1 was obtained in the first visual field test; a second probability density function acquisition unit performs step (4) of obtaining a probability density function f(x2) by removing probability density values that's greater than or equal to t1, or removing values that are less than t1 from f(x1); and a determination unit performs step (5) of determining if a standard deviation σ of the f(x2) is below a predetermined value.
