1) The author established the representation of the lower motor center of all the extrinsic ocular muscles by means of HRP labeling in the rat. 2) The muscles which are supplied by the neurons on both sides of the oculomotor nuclei are the levator palpebrae superioris, superior rectus, medial rectus, inferior oblique, inferior rectus, superior oblique and lateral rectus. 3) The muscles which ar...

Although the surgical treatment is a relatively effective and predictable method for correcting residual or recurrent strabismus, such as posterior fixation sutures, medial rectus marginal myotomy, unilateral or bilateral rectus re-recession and resection, unilateral lateral rectus recession and adjustable suture, no standard protocol is established for the surgical style. Different surgical ap...

PURPOSE To report consecutive esotropia in contralateral lateral rectus recession and medial rectus resection for recurrent intermittent exotropia after unilateral lateral rectus recession and medial rectus resection and to evaluate the surgical outcome of modified contralateral lateral rectus recession and medial rectus resection for exotropia after unilateral lateral rectus recession and medi...

BACKGROUND The association of oblique palpebral fissures and A- or V-pattern has not been clarified. We report two cases of A-pattern esotropia with marked mongoloid slanting palpebral fissures associated with vertical displacement of the horizontal rectus muscle. CASES Case 1 was a boy with Prader-Willi syndrome. He showed A-pattern esotropia with upward slanting palpebral fissures. Severe s...

Eighty-five adults with horizontal concomitant strabismus were treated with an injection of a low dose of botulinum toxin A (BTXA) into the lateral or medial rectus muscle. The ocular deviation was reduced by an average of 60% independently of its size and whether or not surgery had previously been performed. The change was temporary, however, except in those cases with binocular functions, whe...

PURPOSE Although the rectus abdominis and its sheath are well known structures, their development in the human fetus is poorly understood. MATERIALS AND METHODS We examined rectus abdominis and sheath development in semiserial horizontal sections of 18 fetuses at 5-9 weeks of gestation. RESULTS Rectus muscle differentiation was found to commence above the umbilicus at 6 weeks and extend inf...

Atrophy developing in the quadriceps femoris muscle following knee injury is one of the serious problems not only in the field of orthopedics but also of rehabilitation. However the pathogenesis of this atrophy has not yet been elucidated. The author therefore produced a complex ligament injury model using the knee joints of rats in order to study the pathogenesis of this atrophy. After severin...

113 To the Editor: Ophthalmoplegia can cause diplopia, with a lot of etiologies including cerebrovascular disease. Nuclear ophthalmoplegia resulted from brainstem infarction is often accompanied by other symptoms of brainstem dysfunction. It is fairly rare that midbrain infarction only manifests as isolated medial rectus nuclear palsy. Here, we provided such an uncommon case and discussed the p...
