purpose : we describe clinical and radiologic findings and surgical outcome of an orbital dermoid cyst located in the superior oblique muscle tendon. this unusual location for dermoid tumors has not been reported previously. case report : a 15-year-old girl referred to us with an orbital mass in superonasal quadrant of the left orbit reportedly to be present from birth. computed tomography reve...

this article presents a new technique for weakening the superior oblique muscle by lengthening it's tendon. lengthening is accomplished by a nasal superior oblique tenotomy, and by inserting a segment of silicone band 240 between the cut ends of the tendon. this technique is useful for the treatment of brown syndrome and cases with superior oblique overaction.

Background: In 1991, Wright described a superior oblique expander procedure for browns syndrome and superior overaction with good results. Originally, this procedure has been performed with silicone band expander. The aim of this study was to report the results of treatment of a series of patients with A-pattern strabismus associated with overacting superior oblique muscle using the fascia lata...

BACKGROUND AND PURPOSE Congenital superior oblique palsy is known to relate to trochlear nerve absence and a variable degree of superior oblique muscle hypoplasia. The purpose of this study was to determine whether superior oblique muscle volume predicts trochlear nerve absence in congenital superior oblique palsy. MATERIALS AND METHODS A retrospective study of high-resolution MR imaging to e...

PURPOSE To report masked superior oblique muscle tightness as a possible mechanism causing A-pattern exotropia with intorsion after inferior rectus muscle recession in the context of thyroid eye disease. METHODS Three patients with thyroid eye disease and involvement of the superior oblique muscle are presented, along with a fourth comparison case without superior oblique muscle involvement. ...

AIM To identify ARIX gene polymorphisms in patients with congenital superior oblique muscle palsy and to find the relation between the ARIX gene and congenital superior oblique muscle palsy. METHODS The three exons of the ARIX gene were sequenced by genomic DNA amplification with polymerase chain reaction (PCR) and direct sequencing in 15 patients with superior oblique muscle palsy (13 with c...

PURPOSE To search for a new definition of muscle hypoplasia in congenital or idiopathic superior oblique muscle palsy. DESIGN Retrospective case-control study. METHODS Cross-sectional areas of the superior oblique and 4 rectus muscles near the eye globe-optic nerve junction were measured by an image analysis software on magnetic resonance images of 50 patients with congenital or idiopathic ...
