Long-Term Use of Selective Serotonin Reuptake Inhibitors and Risk of Glaucoma in Depression Patients

This study investigated whether the long-term use of selective serotonin reuptake inhibitors (SSRIs) influences the risk of primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG) in the Chinese ethnic population in Taiwan.The authors retrieved the data under analysis from the National Health Insurance Research Database in Taiwan and identified 26,186 newly diagnosed depression patients without preexisting glaucoma. The study cohort included 13,093 patients with over 1 year of SSRI use, and a comparison cohort of 13,093 patients who had never used SSRIs. The main outcome was a diagnosis of POAG or PACG during follow-up. The authors used univariable and multivariable Cox proportional hazards regression models to assess the effects of SSRIs on the risk of POAG and PACG.The cumulative incidences of POAG and PACG between the SSRI and comparison cohorts exhibited nonsignificant differences (log-rank test P=.52 for POAG, P=.32 for PACG). The overall incidence of POAG in the SSRI cohort was nonsignificantly higher than that in the comparison cohort (1.51 versus 1.39 per 1000 person-years), with an adjusted hazard ratio of 1.07 (95% confidence interval=0.82-1.40). The overall incidence of PACG in the SSRI cohort was nonsignificantly lower than that in the comparison cohort (0.95 versus 1.11 per 1000 person-years), with an adjusted hazard ratio of 0.85 (95% confidence interval=0.62-1.18).The long-term use of SSRIs does not influence the risk of POAG or PACG in depression patients.
