Neurofibromatosis type 2 usually presents with bilateral acoustic schwannomas. We highlight the rare presentation of neurofibromatosis initially involving third nerve. A 23-year-old Malay female presented with left eye drooping of the upper lid and limitation of upward movement for 8 years. It was associated with right-sided body weakness, change in voice, and hearing disturbance in the right ear for the past 2 years. On examination, there was mild ptosis and limitation of movement superiorly in the left eye...

Pituitary adenomas usually arise from the anterior lobe of the pituitary gland and are manifested with hormonal disorders or mass effect. Mass effect usually occurs in nonfunctional tumors. Pituitary adenomas may be manifested with visual field defects or rarely in the form of total oculomotor palsy. Visual field defect is most frequently in the form of bitemporal hemianopsia and superior temporal defect. Sudden loss of vision, papilledema and ophthalmoplegia may be observed. Pituitary apoplexy is defined as an acute clinical syndrome characterized with headache, vomiting, loss of vision, ophthalmoplegia and clouding of consciousness...

Stomatognathic system is strictly correlated to other anatomical regions; many studies investigated relationship between temporomandibular joint and posture, several articles describe cranio-facial pain from dental causes, such as trigger points. Until now less interest has been given to connections between dental occlusion and ophthalmology, even if they are important and involving. Clinical experience in dental practice claims that mandibular latero-deviation is connected both to eye dominance and to defects of ocular convergence...

The authors report a rare case of an intracranial dermoid cyst found in Meckel's cave. A 63-year-old woman developed left oculomotor nerve palsy and was referred to their hospital. Magnetic resonance imaging revealed a cystic lesion in the left Meckel's cave and prepontine cistern, but her symptoms gradually improved during conservative observation. However, three years later she complained of left facial pain in the territory of the second branch of the trigeminal nerve. The left oculomotor nerve palsy exacerbated again...

INTRODUCTION: Visual impairment, specifically eye movement disorders and vestibular dysfunction may have a negative influence on the functional recovery in post-stroke patients. This type of sensory dysfunction may further be associated with poor functional outcome in patients' post-stroke. METHODS: In phase 1, a cross-sectional survey (n = 100) will be conducted to determine the prevalence of eye movement disorders and vestibular dysfunction in patients who sustained a stroke...

Ophthalmic complications associated with endoscopic sinus surgery (ESS) are quite rare. There is a paucity of reliable data and limited experience on the clinical findings and treatments of these injuries. Our study here is to characterize the types of orbital injury following ESS, in particular extraocular muscle injury, and to evaluate the long-term therapeutic outcomes as compiled from a relatively large sample of Chinese patients.A series of 27 patients (21 males and 6 females; mean age = 42.6 years, ranges: 10-60 years) were retrospectively reviewed...

BACKGROUND: Autosomal recessive cerebellar ataxias (ARCA) are a group of neurodegenerative disorders characterized by early onset of gait impairment, disturbed limb coordination, dysarthria, and eye movement abnormalities, most likely due to the degeneration of cerebellum, brainstem, and spinal cord. Despite of the rarity, ARCA are both clinically and genetically heterogeneous. To date, more than 30 culprit genes have been identified in ARCA. Unraveling the specific causative mutation in cases with ARCA remains challenging so far...

Neuro-ophthalmic emergencies can cause life-threatening or sight-threatening complications. Various conditions may have acute neuro-ophthalmic manifestations, including inflammatory or ischemic processes, as well as tumoral, aneurysmal compression or metabolic and systemic diseases. Diplopia related to a partial third nerve palsy with pupillary involvement may reveal an intracranial aneurysm. Abnormalities of conjugate gaze may reveal an inflammatory or ischemic lesion, most often of the brainstem. An intracranial tumor may also manifest itself as a single or multiple oculomotor palsy, or causing various visual field defects, due to optic nerve, chiasm or retrochiasmal involvement...

BACKGROUND: Tumors of the middle fossa or cavernous sinus (CS), or intraorbital tumors, can penetrate each other through the superior orbital fissure (SOF) or neighboring tissue. These complicated pathologies are often treated with highly invasive surgical procedures. In this article, we demonstrate surgical anatomic dissections of the CS, SOF, orbital apex (OA), and dura mater extending to the periorbita from the middle fossa, by performing an epidural dissection via a lateral orbitotomy approach, and discuss findings that may provide guidance during surgery in these regions...

Oculomotor nerve palsy can be due to varied causes that include diabetic neuropathy, myasthenia gravis, brainstem infarction, demyelinating conditions, and cerebral aneurysms. Among the aneurysmal causes of oculomotor nerve palsy, aneurysm of the posterior communicating artery has been observed to be the most common. Pupillary dysfunction is considered to be an important feature of aneurysmal oculomotor nerve paresis. A case of a 7-year-old boy with partial oculomotor nerve palsy with pupillary sparing is being reported here, the etiology of which is tortuous and ectatic distal internal carotid artery...

We describe a patient with oculomotor nerve palsy due to secondary orbital infiltration from the primary malignant lymphoma of the cheek. The patient was a 78-year-old female who had non-Hodgkin lymphoma (diffuse large B cell lymphoma [DLBCL]) of the cheek. The patient received chemotherapy and local radiation therapy. The combined treatment brought about complete remission. About 6 months after the last treatment the patient began to have left blepharoptosis and impaired vision. Findings from ophthalmological and neurosurgical examinations suggested no intraorbital or intracranial lesions...

BACKGROUND AND AIMS: Intra-operative identification and preservation of extraocular motor nerves is one of the main goals of surgeries for skull base tumours and this is done by monitoring the extraocular movement (EOM). Intra-operative electromyographic monitoring has been reported, but it is a complex and skilful process. Electrooculography (EOG) is a simple and reliable technique for monitoring EOMs. We aimed to assess the utility of EOG monitoring in preventing extraocular motor nerve dysfunction during skull base surgeries...

PURPOSE: The cisternal segments of the oculomotor nerve (OMN), which courses through the interpeduncular and oculomotor cisterns (OMC) have not been well delineated on neuroimages. The present study aimed to explore the cisternal segments of the OMN using magnetic resonance (MR) imaging. METHODS: A total of 92 patients were enrolled in this study. A constructive interference in steady-state sequence was performed in coronal and axial sections. RESULTS: On coronal images, cisternal portions of the OMN were entirely delineated in 97 % on the right and in 98...
