The relevance of stereopsis for motorists: a pilot study

摘要: Purpose: To study the influence of stereoscopic depth perception on automobile driving performance. Methods: Ten patients with strabismus and defective stereopsis were compared ten healthy controls respect to their performance in a series manoeuvres. The two groups individually matched as age, annual miles driven, years licence holding type vehicle owned. After an ophthalmologic examination subjects each group performed following tests: (1) stopping front obstacle, (2) reversing into parking space, (3) through slalom course, (4) estimating relative positions cars. All tests binocularly monocularly (with non-dominant eye covered). Results: Only test did normal perform significantly better than stereo-deficient (odds ratio 10.5; P<0.01). In position, actually worse 0.091; A significant distance 2.5 (95% CI 1.1–5.5; P=0.033) monocular binocular was found for task only, while showed no difference between Conclusion: this study, had positive effect only dynamic situations at intermediate distances.
