purpose : to evaluate the results of anterior and nasal transposition (ant) of the inferior oblique muscle (io) in patients with the io muscle overaction methods : this retrospective case series included patients with io muscles overaction, in whom ant of the io muscle was performed. in patient with simultaneous horizontal deviation, horizontal strabismus surgery was also performed. they were e...

Purpose To report a case of inferior rectus muscle hypoplasia with esotropia, which was treated successfully by resection and anterior transposition of the inferior oblique muscle. Observations A 1-year-old boy presented with esotropia. He had esotropia of 15-30° and intermittent left hypertropia. At the age of 3 years, the alternate prism cover test showed esotropia of 35Δ and left hypertrop...

BACKGROUND Anterior transposition of the inferior oblique muscle is a popular treatment for dissociated vertical divergence. It seems that this surgical procedure may alter the palpebral fissure. OBJECTIVES To investigate the alteration of the palpebral fissure with inferior oblique muscle anterior transposition when it is performed as the sole operative procedure and to report the cases of p...

BACKGROUND/AIMS Among the various weakening techniques of inferior oblique muscle overaction, the most commonly used techniques include myectomy, recession, and anterior transposition. Anterior transposition and myectomy were compared to evaluate the surgical results in inferior oblique overaction. METHODS 20 children with bilateral +3 overacting inferior oblique muscles underwent a prospecti...

BACKGROUND The anti-elevation syndrome is an adverse outcome of anterior transposition of the inferior oblique muscle. The presumed cause is an excessive anti-elevating force vector that occurs with attempted elevation in abduction. This causes apparent overaction of the contralateral inferior oblique muscle due to fixation duress. It has been suggested that excessive residual extorsion may hel...

We report the effects of unilateral recession-resection surgery of the horizontal recti muscles with inferior displacement and augmented anterior transposition of the inferior oblique muscle with a posterior intermuscular suture in a patient with large exotropia and considerable hypertropia.

PURPOSE To evaluate the efficacy of transposition of the belly of the inferior oblique muscle in treating inferior oblique overaction with small angle hypertropia. METHODS The medical records of 10 patients who underwent inferior oblique belly transposition from March 2014 to July 2016 were reviewed. Transposition of the inferior oblique muscle belly consisted of suturing the entire body of t...
