The authors, in an extensive 2-year study commissioned by Pharmacia & Upjohn, Uppsala, Sweden, describe patterns of care for patients newly diagnosed with primary open-angle glaucoma or ocular hypertension in 6 Western European countries, Australia, Canada, and the United States. The observational data are then used in detailed Markov cost-simulation models to examine differences in direct costs of care during the first 2 years after diagnosis. The authors are to be commended for completing such an ambitious and challenging project. The study makes several important contributions, albeit with several limitations.
