Cerebral palsy (CP) and Duchenne muscular dystrophy (DMD) are neuromuscular disorders characterized by muscle weakness. Weakness in CP has neural and non-neural components, whereas in DMD, weakness can be considered as a predominantly non-neural problem. Despite the different underlying causes, weakness is a constraint for the central nervous system when controlling gait. CP demonstrates decreased complexity of motor control during gait from muscle synergy analysis, which is reflected by a higher total variance accounted for by one synergy (tVAF1 )...

Here, we report a rare case of bilateral medial rectus palsy following closed head injury. An adult male had an accidental fall which rendered him unconscious. This was followed by diplopia and restricted ocular motility. He received supportive medical therapy. He was examined for systemic medical and ophthalmic findings. Routine laboratory tests and imaging techniques were employed as per the symptoms. Diffusion-weighted imaging on magnetic resonance imaging proved it to be a rare presentation of small bilateral midbrain infarct...

Y P Li, W Zhang
Divergence insufficiency is acquired esotropia at distance fixation with symptomatic uncrossed diplopia but fusion at near. It can be divided into two forms: primary isolated form and secondary form associated with neurologic abnormalities, also called divergence palsy. The clinical features of divergence insufficiency include small esotropia only at distance but orthotropia or small esophoria at near, comitant deviation at lateral gaze, reduced divergence fusion, full abduction and normal saccadic velocities in abduction...

Moebius syndrome is characterized by congenital facial palsy and limitation in horizontal gaze. The surgical results of the exotropic pattern are rare and have not been published before. The authors report three cases of exotropic Moebius syndrome. Maximal weakening of the lateral rectus muscles followed by strengthening of the medial recti in exotropic Moebius syndrome can improve exotropia significantly. Most of these cases also need some measures to relieve the often associated severe dry eye. [J Pediatr Ophthalmol Strabismus...

A 46-year-old male patient was referred to our clinic with complaints of diplopia and esotropia in his right eye that developed after a car accident. The patient had right esotropia in primary position and abduction of the right eye was totally limited. Primary deviation was over 40 prism diopters at near and distance. The patient was diagnosed with sixth nerve palsy and 18 months after trauma, he underwent right medial rectus muscle recession. Ten months after the first operation, full-thickness tendon transposition of the superior and inferior rectus muscles (with Foster suture) was performed...

Oculomotor abnormalities are rarely noted in thalamic strokes. We describe isolated right pseudoabducens palsy in a young patient with acute left thalamic infarction revealed by diffusion-weighted magnetic resonance imaging. The patient's horizontal diplopia and oculomotor palsy resolved within 3days. This case supports the hypothesis that a lesion can cause isolated esotropia by interrupting descending inhibitory convergence pathways that traverse the paramedian thalamus and decussate in the subthalamic region to innervate the contralateral third oculomotor nucleus...

Isolated medial rectus palsy due to mesencephalon lesion is extremely rare. We here describe a patient of midbrain infarction involving the medial rectus subnuclei presenting as isolated medial rectus palsy. Axial diffusion-weighted and coronal T2-weighted magnetic resonance imaging showed acute ischemic lesion in mesencephalon.

Central serous chorioretinopathy (CSCR) is an incompletely understood condition in which a primary dysfunction of the choriocapillaris, retinal pigment epithelium, or both causes a detachment of the neurosensory retina. We report the first case of CSCR as a complication of strabismus surgery and explore pathogenic mechanisms.

A woman aged 60 years developed a Millard-Gubler syndrome after a diagnosis of a cavernous angioma in the median and paramedian areas of the pons. In this context, she presented a right VI nerve palsy, right conjugate gaze palsy, facial palsy and left hemiparesis. To improve the complete VI nerve palsy, we planned a modified transposition approach, in which procedure we made a partial transposition of vertical rectus with a silicone band that was fixated posteriorly. After the procedure, the patient gained the ability to slightly abduct the right eye...
