Purpose: The application for a physical disability certificate for vision is certified with either the Goldmann perimeter (GP) or the Humphrey field analyzer (HFA). However, some discrepancies in the results have been noted. This study compared the results between GP and HFA in the same case.
Subjects and methods: Included patients were defined as those who underwent both GP and HFA to apply for a physical disability certificate in four years since 2019. The proportion of patients who fell into the mild category with HFA compared with GP was examined using ordinal logistic regression analysis of differences by causal disease adjusted for age and gender.
Results: A total of 137 patients were included in this study. The average age was 62.1±15.0 years, and the proportion of men was 50.4%. The causative diseases were glaucoma in 56 cases, optic nerve disease in 28, macular disease in 22, and retinitis pigmentosa in 21 cases. Compared with glaucoma, the proportion of the patients who were classified as mild in the visual impairment grade of HFA was significantly higher in those who had retinitis pigmentosa (adjusted odds ratio 3.9, p=0.01) and optic nerve disease (adjusted odds ratio 3.4, p=0.04). No differences concerning age or gender were noted.
Conclusion: The evaluation of physical disability ratings using GP and HFA tend to differ depending on the disease.
