The purpose of this study was to examine the effects of an educational intervention, designed to occupy the waiting time in an eye clinic, on learning about glaucoma and patient satisfaction. Subjects (N = 100) waiting in the eye clinic were randomly assigned to 2 groups: (1) educational intervention and (2) usual clinic care (no structured education during the waiting time in the clinic). Patients who were taught in the clinic had significant gains in knowledge about glaucoma from pretest to posttest and were more satisfied with the education received during the visit.
