OBJECTIVE: To investigate the probability of undergoing filtration surgery in either one or both eyes in patients in whom open-angle glaucoma was newly diagnosed. METHODS AND DESIGN: A retrospective community-based study of 295 residents of Olmsted County, Minnesota, in whom open-angle glaucoma was newly diagnosed between January 1st, 1965, and December 31st, 1980, was performed. Kaplan-Meier methods were used to estimate the cumulative probability of undergoing filtration surgery during a 20-year period. RESULTS: At 20 years of follow-up, the Kaplan-Meier cumulative probability of undergoing filtration surgery in at least one eye was estimated to be 23% (95% confidence interval, 16-30%), and in both eyes the estimate was 12% (95% confidence interval, 6-17%). Patients with optic nerve damage at the time of diagnosis were more likely to undergo surgery than patients with elevated intraocular pressure but no damage (one eye, 39% versus 15%; both eyes, 27% versus 5%). CONCLUSIONS: This retrospective study of a white population newly diagnosed as having and treated for open-angle glaucoma indicates that while most patients did not undergo filtration surgery in the course of glaucoma therapy, at least one-third of those with glaucomatous damage at the time of diagnosis underwent filtration surgery.
