ocular motor function in patients with bilateral vestibular weakness
نویسندگان
چکیده
introduction: patients with bilateral weakness (bw) have many difficulties in gaze stability that interfere with their normal function. the aim of this study was to evaluate ocular motor functions in patients with bw to better understand the problem of gaze instability in these patients. materials and methods: patients were referred from the otolaryngology department for vestibular assessment to our clinic between november 2014 and march 2015. we assessed ocular motor function (gaze, saccade, and smooth pursuit) in patients over the age of 18 years with bw, as verified by a caloric test. results: seventy-eight patients completed all the tests. the mean age of patients was 51.9 (±15.9) years, and 47 (60%) were female. abnormal results were found in five (6.4%), 32 (41%), and seven (9%) patients with respect to gaze, smooth pursuit, and saccade, respectively. there were positive but relatively weak relationships between age and ocular motor results. conclusion: patients with bw suffer from dizziness and unsteadiness. these patients have abnormal function in ocular motor (especially smooth pursuit) tests. the ocular motor dysfunction is responsible for gaze instability in static positions such as standing.

متن کاملLong-term changes of central ocular motor signs in patients with vestibular migraine.
BACKGROUND A high percentage of patients with vestibular migraine (VM) were reported to have central ocular motor dysfunctions (COMD) in the symptom-free interval. Since VM is a chronic disorder, it is of interest if COMD worsen over time. METHODS Thirty VM patients and 11 control patients participated in an 8-year-long observational study with follow-up. All patients underwent standardized n...
