PURPOSE: To analyze 10-year trends in utilization of visual field (VF) tests for adult glaucoma or glaucoma-suspect patients using the Korean Health Insurance Review and Assessment (HIRA) data. METHODS: Health claims for the years 2010 to 2019 as recorded via the Republic of Korea's HIRA service were accessed. We identified glaucoma patients using the glaucoma diagnostic codes H40 (glaucoma) and H42 (glaucoma in other diseases classified elsewhere). For verification of the glaucoma diagnosis, information on any anti-glaucoma prescriptions and ocular surgery history also was obtained. VF testing data was isolated using procedural codes E6690 (kinetic perimetry) and E6691 (standard automated perimetry [SAP]) performed in tertiary hospitals. Any changes in VF test utilization were identified using regression trend analysis. RESULTS: From 2010 to 2019, the total number of SAP procedures performed in tertiary hospitals for either glaucoma or glaucoma-suspect patients increased gradually from 93,459 to 216,433. With regard to kinetic perimetry examinations, the total number decreased gradually from 6,364 to 3,792. The yearly average SAP number per patient showed a slight increase, from 1.168 to 1.248 (ß = 0.008, R2 = 0.669, P = 0.004). Meanwhile, the yearly average number of kinetic perimeter examinations per patient showed a significant decrease, from 1.093 to 0.940 (ß = -0.013, R2 = 0.580, P = 0.010). CONCLUSION: Between 2010 and 2019, the yearly average number of SAP procedures performed per glaucoma or glaucoma-suspect patient increased in Korea. Meanwhile, the yearly average number of kinetic perimetry examinations per patient significantly decreased.
