Abstract Purpose:To compare the measurements of the Goldmann perimeter(GP)and the binocular Esterman test(ET), 10-2 program(10-2)with an automatic perimeter for the visual field classification of the visual impairment certification standard revised in July 2018. To compare with Functional Field Score(FFS)class.

Subject and method:The subjects were 88 patients who consented to this study, 52 males, 36 females, and average age 70.1±12.5 years(glaucoma, 60 cases;diabetic retinopathy, 11 cases;retinitis pigmentosa, 3 cases;chorioretinal atrophy, 2 cases;homonymous hemianopia, 5 cases;others, 7 cases). The right and left eyes were measured using GPⅢ/4e, Ⅰ/4e, and Ⅰ/2e, and the kinetic visual field grade and FFS class were classified. Binocular ET and 10-2 were measured with the right and left eyes using the OCTOPUS 900 perimeter, and the static visual field grades were classified.

Results:The number of cases classified as visual field impairment were 39 out of 88. 18 cases(46.2%)had the same grade of kinetic and static classifications. Of the cases in which the visual field grade was classified heavier by static than by kinetic, 13 cases(33.3%)were 1 grade heavier, 3 cases(7.7%)were 2 grades heavier, and 2 cases(5.1%)were 3 grades heavier. In 3 cases 1 grade heavier by kinetic than static(7.7%). Thirty out of 88 cases corresponded to either the kinetic visual field grade or the FFS class. The kinetic visual field grade and FFS class were the same in 19 cases(63.3%), the FFS class was 1 heavier than the kinetic visual field grade in 6 cases(20%), and the kinetic visual field grade was 1 heavier than the FFS class in 5 cases(16.7%).

Conclusion:By Japanese standards, only 46.2% classified in the same class by the kinetic and static visual field testings. Comparing the kinetic visual field grade and the FFS class, 63.3% of the cases had the same classification.
