OBJECTIVE To evaluate the efficacy of treating Knapp class II superior oblique muscle palsy with 7-mm nasal transposition of the ipsilateral inferior rectus muscle combined with recession of the contralateral inferior rectus muscle when the primary position hypertropia is 10 prism diopters (PD) or less. METHOD A retrospective review of 8 consecutive patients with superior oblique muscle pares...

OBJECTIVE To report the effect of weakening the superior rectus and inferior oblique (IO) muscles on ocular rotations. DESIGN Observational case series. We reviewed a 10-year period of medical records of consecutive patients who underwent bilateral 5- to 11-mm (mean, 8.0 mm; SD, 1.1 mm) superior rectus muscle recessions combined with an IO muscle recession, myectomy, or anterior transposition...

FIG. I Superior and inferior rectus muscles are displaced temporally, the nasal tip of each muscle being attached at the temporal end of the original insertion and the temporal tip being attached at the upper or lower end of the lateral rectus. The direction of the vertical rectus muscles is thereby changed, so that they abduct instead ofadducting. The operation is completed with a recession of...

PURPOSE To compare unilateral versus bilateral surgical treatment of esotropia associated with high myopia. METHODS This retrospective study comprised patients who underwent surgery for esotropia with high myopia performed by the first author (Y.M.) between 2003 and 2008. Surgical results and complications were compared between patients who underwent unilateral versus bilateral surgery. RES...

The extraocular muscles are responsible for all eye movements required to track and fix objects. Superior rectus muscle is located in the superior level of orbital cavity, below musculus levator palpebrae superioris , tilted slightly lateral part orbit. In a routine dissection, we found left, unilateral variation with no other structures, such as nerves vessels. abnormal presented two parts - m...

This article describes a 76 year old man that, after lung cancer surgery, showed left extrinsic oculomotor paralysis and contralateral paralysis of the superior rectus muscle associated with bilateral ptosis. Magnetic resonance imaging confirmed a rare situation characterized by an isolated metastasis in the region of the left third cranial nerve nucleus, probably compromising the superior rect...

OBJECTIVE Establish criteria for the diameters of normal extraocular muscles using computerized tomography in a Thai population. MATERIAL AND METHOD Diameters of extraocular muscles (medial, lateral, superior complex, and inferior rectus) were calculated for 200 patients on coronal direction of screening paranasal sinuses. The effects of age and sex were also analyzed. RESULT Normal ranges ...

The purpose of this study was to determine the possible role of the autonomic nervous system in the function of mammalian extraocular muscle. Experiments were carried out on the cat anesthetized with pentobarbital. Stimulation of the cervical sympathetic nerve and the injection of epinephrine increased the tension of the superior rectus muscle. These responses were unaffected by sympathetic ^-r...

PURPOSE To evaluate the feasibility of autologous extraocular muscle grafting as a type of muscle expansion surgery. METHODS The left superior rectus muscle of twenty-nine rabbits was resected and this fragment was attached to the endpoint of the respective right superior rectus (test group). Thereafter, the superior rectus of the left eye was reattached to the sclera (control group). Both gr...
