falls and postural control in older adults with cataracts

background: there is increasing evidence that visual impairment contribute to falling. the aim of this study was to determine the influence of vision impairment of old adult patients with cataract on the occurrence of falls and postural control. methods:according to the results of screening ophthalmic examination, 48 cataract patients (mean±sd aged 68.5 ± 6.08 yrs.) and 50 individuals without any obvious eye disorders (mean age ± sd 70.7 ± 5.97 yrs.) were enrolled in this study. the postural control was determined using the clinical test of sensory interaction and balance (ctsib) and timed up and go (tug) test. results:the results of this study revealed that 18% (n = 9) of the normal individuals and 22.9% (n =11) of the cataract patients had at least two falls in the past 12 months. however, the result of chi-square test did not show any differences between the two groups (p= 0.36). the mean ± sd tug times in cataract and control groups in our study were15.17 ± 3.58 and13.77 ± 4.90, respectively. however, no significant differences were found between the two groups (p= 0.12).the results of ctsib test showed no significant differences between the two groups on standing on the floor with eyes open and eyes closed (p= 0.61,p= 0.89) and on standing on the foam with eyes open and eyes closed (p= 0.32, p= 0.74 ). conclusion:according to the results of ctsib and tug tests, vision impairment of old adultpatients with cataract is not associated with falls and balance disorders. further work including assessment of postural control with advanced devices and considering other falls risk factors are also required to identify predictors of falls in cataract patients.
