KRIEGER, Fernanda Teixeira  and  LAMBERT, Anelise Caron. The effect of overacting superior oblique muscle tenectomy associated with anterior transposition of the inferior oblique muscle in patients with dissociated vertical deviation. Arq. Bras. Oftalmol.

Purpose: To analyze the effect of weakening of the superior oblique muscle (HOS) with anterior transposition of the inferior oblique muscle in patients with dissociated vertical deviation (DVD) associated with overaction of superior oblique muscle. Methods: In 14 patients we analyzed the correction of dissociated vertical deviation, the reduction of the superior oblique overaction, and the reduction of the A pattern. Twenty-eight eyes were submitted to anterior transposition of the inferior oblique, and tenectomy of the superior oblique muscle. Results: The correction of dissociated vertical deviation was 65.5% in right eye (RE) and 61.3% in left eye (LE). The reduction in the superior oblique overaction was 81.8% in and right eye 85.0% in left eye. The A pattern was reduced in 92.2%. All these values were statistically significant (p<0.01). Conclusions: The proposed surgery is effective in the correction of dissociated vertical deviation and overacting superior oblique muscle.
