Peran Tes Dynamic Visual Acuity dan Tes Kalori dalam Menilai Gangguan Keseimbangan pada Pasien T uberkulosis yang Mendapat Terapi Streptomisin

Background: Impaired balance is the side effect of Streptomycin administration which can decrease the quality of life Up till now, there is no research yet on dynamic visual acuity (DVA) and caloric test in tuberculosis (TB) patients receiving streptomycin therapy. Objective: This study aims to look at the accuracy of the examination using DVA in TB patients receiving Streptomycin, compared to using electronistagmography (ENG). Methods: A pre-experimental study was used to determine changes in the vestibular function test results in a group of TB patients before and after56times administrationof Streptomycin, or when subjects complained of balance disorders, with DVA test and caloric test during April-October 2014. Designed diagnostic test was used after treatment to compare the two methods of measurement. Result: After therapy there was 31 (77.5%) out of 40 subjects with caloric examination and in 30 (75%) with DVA examination. The mean value of caloric examination before therapy was 93.5±32.07°/sec and after therapy was 82.30±38.43°/sec, the change was -11.25±50.55°/sec. The median value of increased DVA line before therapy was 0 line and after therapy was 3 line, there was a change of 3 (minimum 0-maximum 5) line. DVA examination has a sensitivity of 83%, a specificity of 27%, positive predictive value 17%, negative predictive value 90%, a positive likelihood ratio 1.13 and a negative likelihood ratio 0.63 with caloric examination as the gold standard. Conclusion: DVA examination can be used as a screening tool in bilateral peripheral vestibular weakness in TB patients who received Streptomycin therapy.
