PURPOSE: To compare patient demographic data; level of severity; and clinical, diagnostic, and surgical practice patterns in patients with primary open-angle glaucoma (POAG) in an academic setting (AS) versus non-academic setting (NAS) using the American Academy of Ophthalmology IRIS® Registry (Intelligent Research in Sight). METHODS: A retrospective cohort study of IRIS® Registry data that included patients with POAG who were seen between January 2016 and December 2019 and had at least one year of follow-up. RESULTS: Of 3,707,084 distinct eyes with POAG, 3% (109,920) were included in the academic subcohort and 97% (3,597,164) were included in the non-academic subcohort. Among the findings of greatest note (P < .0001 for all comparisons) were a higher proportion of eyes of Black patients, a higher proportion of eyes with level 3 severity, and a higher mean cup-to-disc ratio in eyes in the AS. The relative frequency of gonioscopy, pachymetry, and visual field testing in conjunction with new patient visits was also notably higher in the AS. For glaucoma surgical procedures, the greatest proportional differences in relative frequency were seen for tube shunt procedures (2.55-fold higher in the AS), iStent and Hydrus procedures (2.52-fold higher in the NAS), and endoscopic cyclophotocoagulation (5.80-fold higher in the NAS). CONCLUSIONS: Based on IRIS® Registry data, notable differences appear to exist with regard to ethno-racial groups, glaucoma severity, and diagnostic and surgical practice patterns in AS versus NAS. By understanding these differences, potential opportunities exist in the development of educational programs related to clinical and surgical glaucoma care.
