Face recognition characteristics in patients with age-related macular degeneration determined using a virtual reality headset with eye tracking [Elektronski vir]Žugelj, Nina ...Background and objectives: Face recognition is one of the most serious disabilities of patients with age-related macular degeneration (AMD). Our purpose was to study face recognition using a novel ... method incorporating virtual reality (VR) and eye tracking. Materials and methods: Eighteen patients with AMD (seven male; median age 83 years; 89% with bilateral advanced AMD) and nineteen healthy controls (five male; median age 68 years) underwent the face recognition test IC FACES (Synthesius, Ljubljna, Slovenia) on a VR headset with built-in eye tracking sensors. Analysis included recognition accuracy, recognition time and fixation patterns. Additionally, a screening test for dementia and imaging with fundus autofluorescence and optical coherence tomography was performed. Results: AMD patients had significantly lower face recognition accuracy (42% vs. 92%; p < 0.001) and longer recognition time (median 4.0 vs. 2.0 s; p < 0.001) in comparison to controls. Both parameters were significantly worse in patients with lower visual acuity. In both groups, eye-tracking data revealed the two classical characteristics of the face recognition process, i.e., fixations clustering mainly in the nose-eyes-mouth triangle and starting observation in the nasal area. Conclusions: The study demonstrates usability of a VR headset with eye tracking for studying visual perception in real-world situations which could be applicable in the design of clinical studies.Source: Journal of clinical medicine [Elektronski vir]. - ISSN 2077-0383 (Vol. 13, iss. 2, [article no.] 636, 2024, str. 1-16)Type of material - e-article ; adult, seriousPublish date - 2024Language - englishCOBISS.SI-ID - 185697795
