Background/aims The aim of our study was to investigate the associations between driving self-regulation and glaucoma severity, and between driving self-regulation and glaucomatous visual field (VF) defect patterns.
Methods In 247 patients with primary open-angle glaucoma included in this prospective observational study, a battery of ophthalmic examination was performed, including visual acuity (VA) and VF. Integrated binocular VF was constructed and mean of total deviation (mTD) values in four sectors was calculated (mTDsup-peri, mTDsup-centre, mTDinf-peri and mTDinf-centre). In addition, all participants answered seven questions regarding their avoidance in driving. (1) at night, (2) in rain, (3) in fog, (4) on freeways, (5) lane changing, (6) at high speed and (7) close to the car in front. The associations between these driving behaviours and 10 variables (age, gender, best VA, worst VA, the four sectorial average TD values, years holding a driver’s licence and distance driven per week) were analysed using the generalised linear model with binomial distribution, followed by the model section method using the corrected Akaike information criterion.
Results As a result of the model selection, it was suggested that deterioration of mTDsup-peri was associated with (1) avoiding driving at night and (2) avoiding driving in rain. On the other hand, mTDsup-centre was related to (3) avoiding driving in fog.
Conclusion Damage in visual function was related with driving behaviours in patients with glaucoma.
