Impact of Binocular Visual Field Loss on Driving Performance in Glaucoma Patients
Overview
Affiliations
Aim: To evaluate the driving performance in young and middle-aged Chinese glaucoma patients with mild to severe visual field loss compared to those without glaucoma by using a driving simulation test.
Methods: Twenty-nine participants were included in this study: nine patients with glaucoma but pass the binocular Esterman visual field test, ten patients with glaucoma and fail the binocular Esterman visual field test, and ten age-matched healthy controls. A driving simulation test was designed as a frequency-based analysis of a lane-keeping task. The total performance error, the control-response amplitude and delay were calculated.
Results: Esterman visual field test fail group showed the longest delay of control-response among three groups (=0.02). And the delay in lane-keeping task was significantly associated with inferior field of better-eye (=0.51, =0.004) and integrated visual field (=0.55, =0.002).
Conclusion: Young and middle-aged glaucoma patients with binocular visual field loss suffered from a longer delay of response in driving simulation test, while inferior visual field having more impact than superior visual field.
