Abstract
PurposeTo evaluate racial/ethnic differences in the use of microinvasive glaucoma surgery (MIGS) for the management of mild-moderate primary open-angle glaucoma (POAG) in the United States. DesignRetrospective cohort study. ParticipantsPatients with a diagnosis of mild or moderate POAG, as defined by current procedural terminology (CPT) codes, were included. The experimental group comprised African American (AA) patients and the control group consisted of patients without an AA designation in the TriNetX database. MethodsPropensity scoring was used to match cohorts for age at diagnosis, Charlson Comorbidity Index, sex, nicotine dependence, glaucoma medications, family history of POAG, Body Mass Index, and weight. Outcome was incidence of MIGS over 1 year of follow up. Odds ratios were calculated between cohorts Main Outcome MeasureIncidence of MIGS over 1 year of follow-up post-POAG diagnosis. Results63,418 POAG patients were included (50% AA, 50% non-AA). AA patients were found to undergo MIGS at a significantly lower rate (1,268 of 31,709) compared to non-AA patients (1,508 of 31,709) (OR 0.834, 95% CI: 0.773 – 0.900). ConclusionAlthough POAG is understood to be more prevalent among African Americans, these patients display lower utilization of MIGS, suggesting a possible nationwide racial disparity in the management of POAG.
