Objective: The visual system is one of the 3 most essential systems for maintaining balance. However, the evaluation of refractive error such as myopia has always been neglected in balance studies. This paper aimed to examine the differences in balance and proprioception measurements between individuals with myopia and their healthy peers.
Materials and Methods: Fifteen subjects with myopic eye defects and 15 healthy peers were included in the study. Balance evaluations consisted of the tandem walk test (TWT), the limits of stability test (LOS), and the modified clinical test of sensory interaction and balance (mCTSIB). These evaluations were performed with a computer-aided NeuroCom Balance Master device. Additionally, proprioception was measured with the Biodex System 3 isokinetic dynamometer.
Results: Individuals with myopic defects had higher step widths (P = .001), and end-sway (P = .007) than their healthy peers. The reaction time, maximum excursion, and directional control values of the myopia group were lower than those of the healthy peer group, but there was no difference between the results of the LOS and the m-CTSIB tests (P > .05 for all parameters). Moreover, the 60° proprioception evaluation deviation was higher in the myopia group for both dominant and non-dominant extremities. However, this deviation was not statistically significant (P > .05).
Conclusion: This study showed some differences in the measured values for balance in myopic individuals compared to healthy peers. We think that the evaluation of the participants with the orthoses they use will provide more accurate results from the measurements in future studies evaluating balance and proprioception.
