To determine if glaucomatous visual field defect severity is associated with fear of falling.
This is a cross-sectional study. A total of 387 consecutive subjects with POAG were enrolled in this study along with 293-ocular disease-free control subjects, who were screened at the same institutions. We defined mild POAG as MD of −6 dB or better, moderate POAG as MD of −6 to −12 dB, and severe POAG as MD of −12 dB or worse in the better eye. All participants were requested to answer a questionnaire on fear of falling. Associations between POAG severity and the prevalence of fear of falling were evaluated with the Cochran-Armitage trend test. Multivariable factors including age-adjusted odds ratios (ORs) for the prevalence of fear of falling and 95% confidence intervals (CIs) were evaluated with logistic regression models.
The prevalence of fear of falling was 35/293 (11.9%) in the control group, 38/313 (12.1%) in the mild POAG group, 12/48 (25.0%) in the moderate POAG group, and 6/26 (23.1%) in the severe POAG group, and the trend was statistically significant (P = 0.028 Cochran-Armitage trend test). The adjusted ORs for prevalence in the mild, moderate, and severe POAG groups compared with that in the control group were 1.44 (95% CI: 0.83–2.51), 2.33 (95% CI: 1.00–5.44), and 4.06 (95% CI: 1.39–11.90), respectively.
Among patients with POAG, the severity of visual field defects is associated with fear of falling. (http://www.umin.ac.jp/ctr/index.htm number, UMIN000005574.)
