Studies that evaluate the relationship between strabismus and vestibular functions are very scarce with no consensus between their results. Hence, this study was designed to evaluate vestibular functions in patients with strabismus and to find out the effect of surgical correction of strabismus on vestibular functions.
Materials and methods
Thirty patients with strabismus aged between 10 and 33 years constituted the study group. The following procedures were carried out: otological examinations, detailed vertigo history, neurological and ophthalmological examinations, basic audiological evaluation, office tests for vestibular evaluation, videonystagmography, and computerized dynamic posturography. These vestibular tests either office tests or laboratory tests were performed three times, before eye surgery and 1 month and 2 months after eye surgery.
Before surgery, in office tests for vestibular function, 36.6% of patients had abnormal results in dynamic visual acuity, whereas 26.7 and 16.7% had abnormalities in head thrust and head shake tests. In addition, 43.3% had abnormal sharpened Fukuda stepping test, whereas 33.3 and 13.3% had abnormal CTSIB and Fukuda stepping test. Reduction in equilibrium scores as well as condition 3, 5, and 6 of sensory organization test in all patients showed abnormal videonystagmography test results. Improvement occured postoperatively in office as well as laboratory tests.
Vestibular functions in strabismus patients are globally better in postoperative than in preoperative conditions, and this improvement appeared to be stable.
