A 10-year-old girl presented with esotropia. She had 35 prism diopters of esodeviation at far and near with left inferior oblique muscle overaction (+3). Cycloplegic refraction was +0.5D OD and +0.75D OS, and visual acuity was 20/25 in each eye. The patient was being treated with G-CSF (Leufokine) due to her severe congenital neutropenia (WBC 3350, neutrophil 7.3%, and ANC 170/ul). Despite of l...

A 27 year old woman with systemic lupus erythematosus (SLE) developed vertical diplopia with an apparent bilateral inferior oblique muscle palsy, resulting in a limitation of elevation of the globe in adduction. It resolved with systemic steroid treatment. A transient tenosynovitis affecting the superior oblique tendons was the probable underlying pathological mechanism. This is the first descr...

PURPOSE To clarify the efficacy of a surgical strategy based on the superior oblique tendon traction test. METHODS A retrospective chart review was performed between January 2002 and June 2015. During that period, a single inferior oblique muscle (IO) myectomy and a combined IO myectomy and superior oblique muscle (SO) tuck procedure were performed based on SO tendon looseness as revealed by ...

PURPOSE To establish the surgical results and residual symptoms in 48 cases with unilateral congenital superior oblique muscle palsy that had surgical intervention to the vertical muscles alone. METHODS Myectomy and concomitant disinsertion of the inferior oblique (IO) muscle was performed in 38 cases and myectomy and concomitant IO disinsertion and recession of the superior rectus muscle in ...

PURPOSE To assess the mechanical ability of the inferior oblique neurofibrovascular bundle (NFVB) to act as an ancillary origin for the inferior oblique muscle after anterior transposition. METHODS Stress-strain relations and Young's modulus of elasticity, a measure of tissue stiffness, were determined for the NFVB in vitro, in situ, and in vivo in dynamic and static conditions. For compariso...

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...

PURPOSE To evaluate the outcome of strabismus surgery for congenital superior oblique palsy (SOP) in relation to correction of head tilt and hypertropia. The cohort of patients mainly involved very young children. This is the first study to use a standardized instrument to objectively measure torticollis before and after surgery. MATERIALS AND METHODS A non-comparative interventional case ser...
