Nationwide Analysis of Glaucoma Surgeries in Fiscal Years of 2014 and 2020 in Japan

Nationwide trends in glaucoma surgical procedures were assessed by using the NDB Open Data 2014 and 2020. In Japan, 33,340 non-laser, 54,569 laser, 88,019 total surgeries performed 2014. 2020, 60,108 60,547 120,655 performed. The rates from to 2020 180%, 111%, 137%, respectively. each procedure, angle surgery (326%), tube shunt (383%), ciliary coagulation (489%), gonio-laser (225%) remarkably increased, while iridectomy (75%) iris laser (77%) decreased during same period. An increase was seen young age groups, namely, 55–59 years old younger, non-laser increased 45–49 older. 47.6 48.0 95.6 per 100,000 persons. None of vital statistics, including prefectural population, mean age, rate ≥65-year-old people, significantly associated with number surgeries. Glaucoma practice patterns changed time a new device or procedure introduced. results current study reflected use procedures, such as minimally invasive surgery, shunt, selective trabeculoplasty, micropulse cyclophotocoagulation.
