Rates of Vitrectomy among Enrollees in a United States Managed Care Network, 2001-2012

Overall, we observed an increase in the vitrectomy rates per 1000 enrollees in this large managed care network over the course of the past decade. However, among persons with diabetes mellitus, vitrectomy rates declined substantially over this period. These changes may be explained, in part, by advances in surgical instrumentation and imaging methods to detect retinal diseases changing indications for surgery, improvements in diabetes care, and alternative treatment options for managing retinal conditions. These results may be useful for future planning of manpower needs and highlight the need for aggressive prevention of complications in black persons with diabetes.
