20.500.12556/DiRROS-28983 Head and eye movements during pedestrian crossing in patients with visual impairment a virtual reality eye tracking study Real-world navigation depends on coordinated head–eye behaviour that standard tests of visual function miss. We investigated how visual impairment affects traffic navigation, whether behaviour differs by visual impairment type, and whether this functional grouping better explains performance than WHO categorisation. Using a virtual reality (VR) headset with integrated head and eye tracking, we evaluated detection of moving cars and safe road-crossing opportunities in 40 patients with central, peripheral, or combined visual impairment and 19 controls. Only two patients with a combination of very low visual acuity and severely constricted visual fields failed both visual tasks. Overall, patients identified safe-crossing intervals 1.3–1.5 s later than controls (p ≤ 0.01). Head-eye movement profiles diverged by visual impairment: patients with central impairment showed shorter, more frequent saccades (p < 0.05); patients with peripheral impairment showed exploratory behaviour similar to controls; while patients with combined impairment executed fewer microsaccades (p < 0.05), reduced total macrosaccade amplitude (p < 0.05), and fewer head turns (p < 0.05). Classification by impairment type explained behaviour better than WHO categorisation. These findings challenge acuity/field-based classifications and support integrating functional metrics into risk stratification and targeted rehabilitation, with VR providing a safe, scalable assessment tool. visual impairment virtual reality eye movement pedestrian crossing okvara vida virtualna resničnost gibanje oči prehod za pešce true false true Angleški jezik Slovenski jezik Neznano 2026-04-15 13:54:34 2026-04-15 13:54:34 2026-04-16 04:06:22 0000-00-00 00:00:00 2025 0 0 Nasl. z nasl. zaslona; Opis vira z dne 23. 10. 2025; str. 1-18 no. 5, [article no.] 55 Vol. 18 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 616.1/.4 1995-8692 10.3390/jemr18050055 254466563 RAZ_Mervic_Mark_2025.pdf RAZ_Mervic_Mark_2025.pdf 1 1720159EDB4841320EA882A821FB2C4F e2bba3a7e43637a9f957150321ab883db8cf03fb74b81aa06bbb1a234db4323a 06badf46-38c2-11f1-9cc3-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=43258 https://www.mdpi.com/1995-8692/18/5/55 1 e165fc36-38c1-11f1-9cc3-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=43257 Univerzitetni klinični center Ljubljana 0 0 0
