N2  - BACKGROUND: To assess the driving performance and both the visual scanning and driving compensations of glaucoma patients. <br><br>METHODS: In this case-control pilot study, the driving behavior and performance of 14 patients with glaucoma and 9 healthy age- and sex-similar control subjects were compared in a fixed-base driving simulator. All subjects performed in four scenarios with one to two hazardous situations on urban streets, for a total of five hazards. Measurements taken during the tests included reaction times, longitudinal regulation, lateral control, and eye and head movements. <br><br>RESULTS: Glaucoma patients showed poor driving performance with longer reaction time to hazardous situations than control subjects: pedestrians crossing the road from the left (P<0.022) or from the right (P=0.013), and vehicles coming from the left (P=0.002). Their mean duration of lateral excursion was longer (P=0.045), and they showed more lane excursions in a wide left curve (P=0.045). Glaucoma patients also showed a higher standard deviation of time-headway (P=0.048) with preceding vehicles. Analyses of driving behavioral compensations on curved roads showed that glaucoma patients stayed closer to the center line in large (P=0.006) and small (P=0.025) left curves and on small right curves (P=0.041). Additionally, on straight roads, as compared to control subjects, glaucoma patients showed longer mean time-headway (P=0.032) and lower mean speed (P=0.04). Finally, the glaucoma group exhibited a larger standard deviation of horizontal gaze (P= 0.034) than the control subjects. <br><br>CONCLUSIONS: In a virtual driving environment, glaucoma patients exhibited unsafe driving behaviors, despite their driving and eye-scanning compensations.
