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...

The selectivity of axonal regeneration to the extraocular muscles in teleosts has been reinvestigated by mapping, with retrogradely transported HRP, the motor pools of the muscles innervated by the oculomotor nerve. In normal goldfish, the motoneurons of the superior rectus, inferior rectus, and inferior oblique muscles formed discrete, nonoverlapping motor pools; the motor pool of the medial r...

PURPOSE To employ magnetic resonance imaging (MRI) to seek evidence of compartmental lateral rectus atrophy consistent with a lesion involving selective denervation of only 1 of the 2 neuromuscular compartments of the lateral rectus. DESIGN Prospective observational case-control series. METHODS At a single institution, surface coil coronal MRI was obtained at 312 μm resolution in quasi-coro...

PURPOSE Overcorrection of hypotropia subsequent to adjustable suture surgery following inferior rectus recession is undesirable, often resulting in persistent diplopia and reoperation. I hypothesized that overcorrection shift after suture adjustment may be unique to thyroid eye disease, and the use of a nonabsorbable suture may reduce the occurrence of overcorrection. METHODS A retrospective ...

BACKGROUND AND AIM Rectus muscle insertions are usually linear or slight curved with the anterior convexity. While operating squint surgeries, we found a presence of ridge-like structure at the medial rectus insertion. None of the other rectus muscle insertions had such structure. MATERIALS AND METHODS Patients undergoing squint surgery were included in the study. All the patients had negativ...

The electromyographic (EMG) study of patients with Duane's retraction syndrome has shown that there is a gross abnormality of innervational pattern in this condition. Most commonly the lateral rectus is affected and shows an innervation differing from the normal in several respects. The first description of the EMG pattern in two patients came from Breinin (I957) when he reported little activit...

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...

PURPOSE We report a case of inferior rectus muscle aplasia in a 65-year-old woman. METHODS Images were obtained using ocular motility photography and magnetic resonance imaging (MRI), and operative findings were analyzed. RESULTS A 65-year-old woman presented with marked right hypertropia. The right eye also had microcornea, iris coloboma, and completely restricted downward movement. MRI sh...

33 patients with active, moderate-severe Graves' ophthalmopathy (GO) received 4.5 g methylprednisolone for 12 weeks and were divided by efficacy into two groups (responsive and unresponsive). All patients and 10 controls underwent orbital MRI examination at baseline. No significant difference was seen in baseline clinical characteristics between the two GO groups. The values of exophthalmos wer...
