| Abstract: | OBJECTIVE: The device of subjective visual vertical (SVV) was made to test the gravity orientation of subjects visual. METHODS: The normative value was established firstly in the right, left and both eyes respectively. Then the test was applied to evaluate the function of otolith function (utricular function) in normal adult subjects and examined the SVV in some patients suffered from acute unilateral vestibulopathy. RESULTS: The difference of the SVV among right, left and both eyes was not significant and the normative value was lower than +/- 2 degrees. No matter one eye or both eyes, SVV had the tendency to lateraliseze to the right. CONCLUSIONS: The SVV is a reliable choice to test the otolith vestibulopathy, which is at least suitable for acute phase. The bilateral eyes open mode is recommended to test the subjects suspected of utricuar dysfunction. |
