Resumo: Purpose To investigate the relationship between postural metrics obtained by dynamic visual stimulation in a virtual reality environment and the presence of fear of falling in glaucoma patients. Methods This cross-sectional study included 35 glaucoma patients and 26 controls that underwent evaluation of postural balance by a force platform during presentation of static and dynamic visual stimuli with head-mounted goggles (Oculus Rift). In dynamic condition, a peripheral translational stimulus was used to induce vection and assess postural reactivity. Standard deviations of torque moments (SDTM) were calculated as indicative of postural stability. Fear of falling was assessed by a standardized questionnaire. The relationship between a summary score of fear of falling and postural metrics was investigated using linear regression models, adjusting for potentially confounding factors. Results Subjects with glaucoma reported greater fear of falling compared to controls (-0.21 vs. 0.27

The relationship between a summary score of fear of falling and postural metrics was investigated using linear regression models, adjusting for potentially confounding factors. Results Subjects with glaucoma reported greater fear of falling compared to controls (-0.21 vs. 0.27P = 0.039). In glaucoma patients, postural metrics during dynamic visual stimulus were more associated with fear of falling (R-2 = 18.8%P = 0.001) than static (R-2 = 3.0%P = 0.005) and dark field (R-2 = 5.7%P = 0.007) conditions. In the univariable model, fear of falling was not significantly associated with binocular standard perimetry mean sensitivity (P = 0.855). In the multivariable model, each 1 Nm larger SDTM in anteroposterior direction during dynamic stimulus was associated with a worsening of 0.42 units in the fear of falling questionnaire score (P = 0.001). Conclusion In glaucoma patients, postural reactivity to a dynamic visual stimulus using a virtual reality environment was more strongly associated with fear of falling than visual field testing and traditional balance assessment.Duke Univ, Duke Eye Ctr, Durham, NC 27708 USADuke Univ, Dept Ophthalmol, Durham, NC 27708 USAUniv Fed Sao Paulo, Dept Ophthalmol & Vis Sci, Sao Paulo, BrazilUniv Calif San Diego, Dept Ophthalmol, La Jolla, CA 92093 USAUniv Fed Sao Paulo, Dept Ophthalmol & Vis Sci, Sao Paulo, BrazilWeb of ScienceNational Institutes of Health/National Eye Institute [EY021818]Brazilian National Council for Scientific and Technological Development (CNPq) [233829/2014-8]Alcon Laboratories (Fort Worth, TX)Bausch & Lomb (Garden City, NY)Carl Zeiss Meditec (Jena, Germany)Heidelberg Engineering (Heidelberg, Germany)Merck (White House Station, NJ)Allergan (Irvine, CA)Sensimed (Lausanne, Switzerland)Topcon (Livermore, CA)Reichert (Dewey, NY)National Eye Institute (Bethesda, MD)Novartis (Basel, Switzerland)nGoggle (San Diego, CA)CNPq [233829/2014-8]Public Library Science2020-07-02T18:52:20Z2020-07-02T18:52:20Z2017info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion-application/pdfhttp://dx.doi.org/10.1371/journal.pone.0187220Plos One.
