Geographic Variation in the Use of Diagnostic Testing of Patients with Newly Diagnosed Open-Angle Glaucoma

In many US communities, a high proportion of patients are undergoing testing according to established practice guidelines. However, in several communities, less than 60% of patients with newly diagnosed OAG are undergoing VF testing in the 2 years after initial OAG diagnosis, and in a few communities >1 in 4 patients have no record of glaucoma diagnostic testing of any type. Additional research is needed to understand factors driving this variation in practice patterns and its impact on patient outcomes.
