PURPOSE: Analyze practice patterns of glaucoma surgeons with and without fellowship training. MATERIALS AND METHODS: Physician-specific 2017 Medicare data were obtained from the Centers for Medicare & Medicaid Services website. Current Procedural Terminology codes identified procedures including iStent, tube shunts, trabeculectomy, complicated trabeculectomy, endoscopic cyclophotocoagulation, internal Xen Implant, external Xen or Express shunt, Gonioscopy-Assisted Transluminal Trabeculotomy, and Kahook Dual Blade Goniotomy. Physicians with fellowship training were identified via the American Glaucoma Society website. RESULTS: A total of 1547 glaucoma surgeons were identified, of which 319 had completed fellowship training. Overall, fellowship-trained glaucoma surgeons performed more services (50.4 ± 47.0 vs 40.5 ± 35.3, P < .001) with a larger variety of procedures (1.8 ± 1.0 vs 1.3 ± 0.6, P < .001) than those without fellowship training. Surgeons without fellowship training were more likely to perform iStent and endoscopic cyclophotocoagulation and less likely to perform the remaining procedures than their fellowship-trained counterparts. Medicare payments did not differ between groups and the number of Medicare beneficiaries only differed for internal Xen implant (P = .03). Patient comorbidity burden was similar between groups with about one-third of patients being diagnosed with ischemic heart disease. CONCLUSIONS: Surgeons without fellowship training can treat a similar volume of glaucoma patients as those with fellowship training. However, based on surgical procedures employed, their practices are skewed towards mild and moderate glaucoma and they are more limited in their breadth of procedures. In addition, ischemic heart disease was prevalent in the glaucoma patient population.
