Oculomotor nerve palsy limits the specific direction eyeball movement, and represents diplopia, mydriasis, and ptosis. The vascular-associated etiologies of oculomotor nerve palsy are the microvascular ischemia due to hypertension or diabetes, or compression of the nerve by the aneurysm. For the aneurysm, if not treated properly, it may result in mortality or severe neurological impairment. Thorough history taking, physical examinations, and proper imaging modality are needed to make an accurate diagnosis. A 76-year-old female with decreased mentality and anisocoria presented at our emergency department. An 83-year-old female presented with right ptosis and lateral-side deviated of the right eyeball. No definite lesion was noted on the initial non-contrast brain computed tomography (CT) and magnetic resonance imaging diffusion. An aneurysm was detected on CT angiography taken several hours later in the former patient. For the latter patient, a giant aneurysm was detected on magnetic resonance angiography that had been performed at another hospital 4 days earlier. These two patients underwent transfemoral cerebral angiography with coiling. They were discharged with no neurological sequelae.

Congenital cranial dysinnervation disorders are a group of diseases caused by abnormal development of cranial nerve nuclei or their axonal connections, resulting in aberrant innervation of the ocular and facial musculature. Its diagnosis could be facilitated by the development of high resolution thin-section magnetic resonance imaging. The purpose of this review is to describe the method to visualize cranial nerves III, IV, and VI and to present the imaging findings of congenital cranial dysinnervation disorders including congenital oculomotor nerve palsy, congenital trochlear nerve palsy, Duane retraction syndrome, Möbius syndrome, congenital fibrosis of the extraocular muscles, synergistic divergence, and synergistic convergence.

PURPOSE: The purpose of our study was to evaluate the cause of acquired third, fourth, and sixth nerve palsy while also establishing recovery rates and important factors for recovery. METHODS: A retrospective chart review was performed for 92 patients who visited the ophthalmologic department of Konyang University Hospital with acquired third, fourth, and sixth nerve palsy from March 2015 to February 2016. Recovery rates and factors for recovery were evaluated in only 66 patients who received first ocular exam within 2 weeks of onset and who were followed up for at least 6 months. Complete recovery was defined as both complete recovery of the angle of deviation and the restoration of eye movement in all directions. For the degree of ocular motor restriction, −4 was defined as not crossing the midline and −2 was defined as 50% eye movement. The degree of ocular motor restriction was analyzed from −1/2 to 4. RESULTS: The fourth nerve was affected most frequently (n = 37, 40.2%), followed by the sixth cranial nerve (n = 33, 35.9%), the third cranial nerve (n = 18, 19.6%), and a combination of 2 or more cranial nerves (n = 4, 4.3%). Vasculopathy (n = 44, 47.8%) was the most common etiology, followed by trauma (n = 14, 15.2%), idiopathic (n = 13, 14.1%), inflammation(n = 10, 10.9%), neoplasm (n = 9, 9.8%), and aneurysm (n = 2, 2.2%). Complete recovery rate occurred for 66.7% (n = 44) of patients, and the overall recovery rate (i.e., at least partial recovery) was 86.3% (n = 57). Significant factors for complete recovery were the initial deviation angle and the limitation of extraocular movement (p < 0.001, p = 0.005, respectively, according to univariate analysis). CONCLUSIONS: In this study, paralytic strabismus due to vasculopathy was the most common etiology, and a lower degree of initial deviation resulted in an improved complete recovery rate. In addition, a high overall recovery rate was possible through quick diagnosis and early treatment of cranial nerve palsy.

PURPOSE: To investigate the neuro-ophthalmic diagnosis and clinical manifestations of intracranial aneurysm. METHODS: A retrospective survey of 33 patients who were diagnosed with intracranial aneurysm and underwent neuro-ophthalmic examination from April 2008 to December 2016. Frequency of the first diagnosis of intracranial aneurysm in ophthalmology, neuro-ophthalmic diagnosis, location of intracranial aneurysm, examination of intracranial aneurysm rupture, and neurologic prognosis of Terson's syndrome patients were analyzed by image examination, neurosurgery, and ophthalmology chart review. RESULTS: Of the 33 patients, most patients (n = 31, 94%) were diagnosed with intracranial aneurysm at the neurosurgical department and only 2 patients were diagnosed initially at the ophthalmology department. Causes and association were: Terson's syndrome (n = 10, 30%), third cranial nerve palsy (n = 10, 30%), internclear ophthalmoplegia (n = 4, 12%), visual field defect (n = 3, 9%), optic atrophy (n = 3, 9%), sixth cranial nerve palsy (n = 2, 6%), and nystagmus (n = 1, 3%). The location of intracranial aneurysms were: anterior communicating artery (n = 13, 39%), medial communicating artery (n = 12, 36%), and posterior communicating artery (n = 5, 15%). Ten of 33 patients had Terson's syndrome, and 6 patients (60%) with Terson's syndrome had apermanent neurological disorder such as agnosia, gait disorder and conduct disorder. CONCLUSIONS: Third cranial nerve palsy was the most common neuro-ophthalmic disease in patients presenting with intracranial aneurysm. The neuro-ophthalmic prognoses for those diseases were relatively good, but, if Terson's syndrome was present, neurological disorders (agnosia, gait disorder, conduct disorder) were more likely to remain after treatment.

PURPOSE: To report a case of cavernous sinus dural arteriovenous fistula following Tolosa-Hunt syndrome. CASE SUMMARY: A 64-year-old female with a history of hypertension, presented with blepharoptosis and periorbital pain in the right eye and diplopia. Her right pupil was dilated. She had right exotropia and right hypertropia with inability to elevate, depress, and adduct the right eye. Magnetic resonance imaging including angiography, revealed hyperintensities in the right cavernous sinus consistent with inflammation and no vascular abnormalities. Three days after oral corticosteroid therapy, the pain disappeared. A presumptive diagnosis was Tolosa-Hunt syndrome presenting as a form of complete oculomotor nerve palsy. Two months later, she experienced severe pain in the right periocular area, even though blepharoptosis was resolved and ocular motility was improved. A rapid response to high-dose intravenous corticosteroids was consistent with recurrence of Tolosa-Hunt syndrome. Three months later, she had normal ocular motility, but developed a conjunctival injection, pulsatile orbital bruits, and exophthalmos in the right eye. Cerebral angiography showed a cavernous sinus dural arteriovenous fistula. She received a transvenous coil embolization and her symptoms markedly improved over 2 months. CONCLUSIONS: Tolosa-Hunt syndrome, a granulomatous inflammation in the cavernous sinus may be followed by cavernous sinus dural arteriovenous fistula and should be considered during follow-up.

PURPOSE: To report two patients with positive ice tests who had diplopia and blepharoptosis caused by something other than ocular myasthenia gravis. CASE SUMMARY: A 35-year-old female presented with a one-week history of inability to adduct the left eye and left blepharoptosis. Although the ice test was positive, serum anti-acetylcholine receptor binding antibody and the repetitive nerve stimulation test were negative. Brain angiography showed an aneurysm of the left posterior communicating artery, leading to the diagnosis of left pupil-sparing oculomotor nerve palsy. A 25-year-old female presented with an 8-month history of intermittent horizontal diplopia and blepharoptosis in the right eye. The ice test was positive, however serum anti-acetylcholine receptor binding antibody and the repetitive nerve stimulation test were negative. Anti-nuclear antibody was positive (titer 1:160). CONCLUSIONS: The ice test is a useful screening test for myasthenia gravis. However, a series of differential diagnoses including blepharoptosis and ocular motility disorder should be considered because these conditions also show a positive result in the ice test.

PURPOSE: Isolated oculomotor nerve palsy in preeclampsia patients have not been reported in Korea. Herein, we report 1 case of a patient in her 32nd week of gestation diagnosed with preeclampsia experiencing oculomotor nerve palsy in the left eye which improved after delivery. CASE SUMMARY: 28-year-old pregnant woman in her 32nd week of gestation with no underlying diseases visited our clinic with the chief complaint of diplopia and left eye ptosis. The patient suffered headache symptoms 1 week prior and did not undergo any exams. The visual acuity, anterior segment, and, fundus showed no abnormal signs and the pupil light reflex was normal, but the patient showed left eye ptosis with +2 mm/-2 mm on the marginal reflex distance (MRD) exam, 25 prism exotropia and 6 prism hypotropia, supraduction and adduction limitation -2 and, infraduction limitation -1. To exclude other systemic disorders and brain lesions, laboratory tests and brain magnetic resonance imaging (MRI) was performed, and preeclampsia was diagnosed based on high blood pressure (150/110 mm Hg) and mild proteinuria. Imaging and labatory tests showed other disorders thus the patient was treated conservatively. Two weeks after the ocular symptoms appeared, the left ptosis and ocular movement restriction worsened, but systemic signs and tests shown no aggravation, thus we maintained conservative therapy and after delivery at 37-weeks, the symptoms slowly improved and recovered completely after 2 months. CONCLUSIONS: Full systemic examination including MRI and laboratory tests must be performed in pregnant women who suddenly experience ocular symptoms and are diagnosed as oculomotor motor nerve palsy. If diagnosis and treatment are appropriate, good prognosis can be expected in this disease.

Isolated oculomotor nerve palsy (ONP) attributable to mild closed head trauma is a distinct rarity. Its diagnosis places high demands on the radiologist and the clinician. The authors describe this condition in a 36-year-old woman who slipped while walking and struck her face. Initial computed tomography did not reveal any causative cerebral and vascular lesions or orbital and cranial fractures. Enhancement and swelling of the cisternal segment of the oculomotor nerve was seen during the subacute phase on thin-sectioned contrast-enhanced magnetic resonance images. The current case received corticosteroid therapy, and then recovered fully in 13 months after injury. Possible mechanism of ONP from minor head injury is proposed and previous reports in the literature are reviewed.

Lemierre's syndrome is characterized by anaerobic septicemia, internal jugular vein thrombosis, and septic emboli associated with infections of the head and neck. We describe an unusual and clinically confusing case of a young woman with an acute paresis of the abducens nerve and partial paresis of the right oculomotor nerve. After an extensive imaging diagnostic procedure, we also documented a peritonsillar abscess and various types of thromboses in intracranial and extracranial veins. Furthermore, we found brain and lung abscesses, which led us to establish the diagnosis of Lemierre's syndrome. Despite intensive anti-coagulation and antibiotic therapy, the patient developed a mycotic aneurysm in the right internal carotid artery directly adjacent to the previously thrombosed cavernous sinus. In summary, we were able to confirm that Lemierre's syndrome may occur in conjunction with uncharacteristic symptoms. Due to the sometimes confusing clinical symptoms as well as clinical and radiological specialties, we had to work on an interdisciplinary basis to minimize the delay prior to establishing the diagnosis and therapy.
