Objective: To determine whether racial disparities exist in the use of ancillary testing to evaluate individuals with open-angle glaucoma.
Methods: We identified all enrollees aged 40 years and older in a large US managed care network with retinal or optic nerve conditions that could warrant the use of ancillary testing. Among persons with open-angle glaucoma or glaucoma suspects, we performed repeated-measures multivariable logistic regression to determine the odds and probabilities each year of undergoing visual field testing, fundus photography, and other ocular imaging for black, white, Hispanic, and Asian American men and women and compared the groups.
Purpose: To assess trends in the use of ancillary diagnostic tests in the evaluation of patients with open-angle glaucoma (OAG) and glaucoma suspects over the past decade.
Design: Retrospective, longitudinal cohort analysis.
Participants: A total of 169 917 individuals with OAG and 395 721 individuals with suspected glaucoma aged ≥40 years enrolled in a national United States managed care network between 2001 and 2009.
