Factors affecting resolution of oculomotor nerve palsy following endovascular embolization of posterior communicating artery aneurysms.

PURPOSE: To investigate the effect of endovascular embolization of posterior communicating artery (Pcom) aneurysms on concomitant oculomotor nerve palsy (OMNP) and factors affecting the effect of treatment. MATERIALS AND METHODS: Patients with the Pcom aneurysms concomitant with OMNP were retrospectively enrolled for endovascular treatment of the aneurysms. All patients had the endovascular management. The clinical effect, degree of OMNP, size of the aneurysm, type of treatment, subarachnoid hemorrhage (SAH), and time from onset to treatment were analyzed on the resolution of OMNP. RESULTS: Ninety-six patients with 99 Pcom aneurysms were enrolled and treated endovascularly, with the success rate of 100%. Immediately after endovascular treatment, 75 aneurysms (75.75%) got complete occlusion, and 24 (24.24%) nearly complete occlusion. Followed up for 3-18 (mean 8.52±0.56) months, complete resolution of the OMNP was achieved in 63 patients (65.63%), partial resolution in 21 (21.88%), and non-recovery in the other 12 (12.50%). The degree of OMNP at onset, SAH, and time from onset to treatment were significantly (P<0.05) correlated with the resolution of OMNP. Univariate analysis revealed that younger age of the patient, degree of OMNP at onset, presence of subarachnoid hemorrhage, and time from disease onset to treatment were significantly (P<0.05) associated with the recovery of OMNP. Multivariate analysis revealed that the younger age, degree of OMNP at onset, and time from disease onset to treatment were significantly (P<0.05) associated with the recovery of OMNP. CONCLUSION: Endovascular embolization of Pcom aneurysms concomitant with OMNP can effectively improve the OMNP symptoms, especially for patients with moderate and a shorter history of OMNP. Younger age, degree of oculomotor nerve palsy at onset, and time from onset to treatment may significantly affect recovery of oculomotor nerve palsy.

Acupuncture therapy for isolated ischemic oculomotor nerve palsy: A case report.

BACKGROUND: Isolated ischemic oculomotor nerve palsy as a type of ophthalmic disease is rarely observed in clinical practice. Quality of life is frequently impacted by isolated ischemic oculomotor nerve palsy due to its lack of treatment options and long-term visual impairment. We describe an acupuncture-treated instance of isolated ischemic oculomotor paralysis. METHODS: Acupoints including Jingming (BL 1), Chengqi (ST 1), Cuanzhu (BL 2), and Sizhukong (TE 23) on the right side, and bilateral Fengchi (GB 20), Waiguan (TE 5), Hegu (LI 4), and Zulinqi (GB 41) were selected for needling. Each treatment lasted for 30 minutes, once every other day. Acupuncture treatment was administered for a total of 11 times. RESULTS: Acupuncture is a promising treatment option for isolated ischemic oculomotor nerve palsy. CONCLUSIONS: Ischemic oculomotor nerve paralysis can affect the quality of life of patients. Acupuncture intervention can promote the recovery of the disease is a very effective treatment measure.

Immediate effects of electroacupuncture in oculomotor nerve palsy following brainstem infarction: A case report.

INTRODUCTION: Research has demonstrated that electroacupuncture (EA) stimulation of paralyzed muscles significantly improves nerve regeneration and functional recovery. DESCRIPTION: An 81-year-old man with no history of diabetes mellitus or hypertension presented with a history of brainstem infarction. Initially, the patient had medial rectus palsy in the left eye and diplopia to the right in both eyes, which almost returned to normal after six sessions of EA. METHODS: The CARE guidelines informed the case study report. The patient was diagnosed with oculomotor nerve palsy (ONP) and photographed to document ONP recovery after treatment. The selected acupuncture points and surgical methods are listed in the table. DISCUSSION: Pharmacological treatment of oculomotor palsy is not ideal, and its long-term use has side effects. Although acupuncture is a promising treatment for ONP, existing treatments involve many acupuncture points and long cycles, resulting in poor patient compliance. We chose an innovative modality, electrical stimulation of paralyzed muscles, which may be an effective and safe complementary alternative therapy for ONP.

Acupuncture treated oculomotor nerve palsy with diabetes mellitus: A case reported.

The incidence of diabetes mellitus is increasing rapidly, and this condition often results in severe complications. One such complication, diabetic oculomotor nerve palsy (ONP), that can lead to significant impairment of visual function is increasingly recognized. However, there are few reports in the literature on the treatment of diabetic ONP. In the present case, the use of needling a selection of local and distal acupoints showed promising results for the treatment of diabetic ONP. We also present a brief literature review related to this case.

Effects of endovascular treatment and prognostic factors for recovery of oculomotor nerve palsy caused by posterior communicating artery aneurysms: a multi-center retrospective analysis.

BACKGROUND: Oculomotor nerve palsy (ONP) may result from posterior communicating artery (PcomA) aneurysms. We aimed to evaluate the resolution of ONP after endovascular treatment with the intention of clarifying predictors of nerve recovery in a relatively large series. METHODS: A total of 211 patients with ONP caused by PcomA aneurysms underwent endovascular coiling between May 2010 and December 2020 in four tertiary hospitals. We evaluated the demographics, clinical characteristics, aneurysm morphology parameters and ONP resolution to analyze the predictors of ONP recovery using univariate and multivariate analyses. RESULTS: At the last available clinical follow-up, ONP resolution was complete in 126 (59.7%) patients, partial in 73 (34.6%) patients, and no recovery in 12 (5.7%) patients. The median resolution time after endovascular treatment was 55 days (interquartile range: 40-90 days). In multivariate analysis, degree of ONP (incomplete palsy) on admission (OR 5.396; 95% CI 2.836-10.266; P < 0.001), duration of ONP (≤ 14 days) before treatment (OR 5.940; 95% CI 2.724-12.954; P < 0.001) were statistically significant predictors of complete recovery of ONP. In the subgroup analysis of patients with unruptured aneurysms, aspirin showed a higher complete recovery rate in univariate analysis (OR 2.652; 95% CI 1.057-6.656; P = 0.038). CONCLUSION: Initial incomplete ONP and early management might predict better recovery of ONP after endovascular treatment.

Acupuncture for oculomotor nerve palsy:A systematic review and meta-analysis.

BACKGROUND: To evaluate the safety and efficacy of acupuncture in the treatment of oculomotor nerve palsy (ONP). METHODS: The following database will be required from PubMed, Cochrane Library, Medline, Chinese Biomedical Literature Database, China National Knowledge Infrastructure (CNKI), Wanfang data. Randomized controlled trials (RCTs) comparing acupuncture alone versus no treatment/another active therapy/sham acupuncture or comparing acupuncture with another active therapy versus the same active therapy were included. Meta-analysis was conducted according to the 2020 PRISMA guidelines. Data was analyzed using RevMan 5.4 software. Results were reported as risk ratios (RR) for dichotomous outcomes or mean differences (MD) for continuous outcomes, with 95 % confidence intervals (CI). The Cochrane risk of bias tool was used to access the methodological quality of the trails. RESULTS: Eighteen RCTs with 1150 participants comparing acupuncture versus other therapies were included. The results showed a significant differences in the clinical efficiency rate (RR = 1.30, 95 %CI = 1.23-1.37, P < 0.001), scores of diplopia (MD = - 0.78, 95 %CI = - 1.39 to - 0.77, P < 0.001), palpebral fissure size (MD = 1.04, 95 %CI = 0.41-1.68, P = 0.001), the pupil diameter (MD = - 0.56, 95 %CI = - 0.70 to - 0.42, P < 0.001), quality of life (MD = 8.96, 95 %CI = 6.79-11.13, P < 0.001) between the experiment and control groups. However, there were no significant differences in the adverse effects (RR = 0.52, 95 %CI = 0.22-1.22, P = 0.13). The quality of the evidence test by GRADE was low or very low. CONCLUSION: Most included studies suggested that acupuncture was more effective than the control group in the treatment of ONP. However, the quality evidence of most of the studies was low and most of them were performed in China.

A bibliometric analysis of research on the treatment of facial nerve palsy.

BACKGROUND: There are various treatments for facial nerve palsy, and research into this topic is ongoing. In the present study, we carried out bibliometric and visualized analyses to identify the trends of research into facial nerve palsy treatment. METHODS: To identify articles, the SCOPUS database was searched for articles published from its inception to December 27, 2020. The search was conducted twice, with Search 1 investigating general treatment trends and Search 2 narrowing the scope to complementary and alternative treatment. The extracted keywords were analyzed using the Visualization Of Similarities (VOS) viewer. Through analysis of keywords, research hotspots in the treatment of facial nerve palsy were identified. RESULTS: A total of 1609 and 223 articles were identified in Searches 1 and 2, respectively. The number of articles published each year showed a tendency to increase, and most of the studies were only conducted in a few countries. In terms of subject area, "medicine" was overwhelmingly the most common(77.6%). Based on the analysis of 316 keywords in Search1, "medication treatment," and "complementary and alternative treatment" were the hotspots of research. CONCLUSION: This study provides the overall trends of facial nerve palsy treatment. To date, research on medication treatment has been main focus, and antiviral use among medication treatment and complementary and alternative treatment has emerged in recent years.

Nasopharyngeal B-cell lymphoma with pan-hypopituitarism and oculomotor nerve palsy: a case report and review of the literature.

BACKGROUND: Primary nasopharyngeal lymphoma (NPL) is a very rare tumor of Waldeyer ring (WR) lymphoid tissue. It is challenging to differentiate lymphoma infiltration of pituitary from a pituitary adenoma, meningioma infiltration, and other sellar lesions to plan a suitable treatment strategy. We presented for the first time a unique case of NPL with an unusual presentation of oculomotor nerve palsy associated with pan-pituitary involvement in a diabetic patient. CASE PRESENTATION: A 64-year old diabetic woman with no previous history of malignancy presented with intermittent diplopia for about the last nine months. Severe headache, left eye ptosis and hypoglycemic episodes were added to her symptoms after a while. Further complaints include generalized weakness, loss of appetite, generalized musculoskeletal pain, and 6-7 kg weight loss within six months. Her family history was unremarkable. Physical examinations of eyes indicated left eye 3rd, 4th, and 6th nerve palsy. But, she was not anisocoric, and the pupillary reflexes were normal on both eyes. No lymphadenopathy, organomegaly and other abnormalities were found. Magnetic resonance imaging (MRI) showed a heterogeneous enhancement in the seller and suprasellar regions, enlargement of the stalk, parasellar dural enhancement and thickening of the sphenoid sinus without bone erosion. Also, both cavernous sinuses were infiltrated and both internal carotid arteries were encased by the neoplastic lesion. It suggested an infiltrative neoplastic lesion which compressed the cranial nerves. Pituitary hormone levels assessment indicated a pan-hypopituitarism. Following nasopharyngeal mucosal biopsy, the immunohistochemistry (IHC) findings revealed a low-grade non-Hodgkin's B-cell lymphoma. Systemic workup, including cerebrospinal fluid (CSF) studies, bone marrow aspiration, chest and abdominopelvic high-resolution computed tomography (HRCT) indicated no other involvement by the lymphoma. After chemotherapy courses, central adrenal insufficiency, partial central diabetes incipidious (CDI) and central hypothyroidism have been resolved. To our best knowledge, we found 17 cases of NPL with cranial nerve palsy, 1 case of NPL with pan-hypopituitarism and no NPL case with both cranial nerve palsy and pituitary dysfunction. CONCLUSIONS: The incidence of cranial neuropathy in patients with diabetes should not merely be attributed to diabetic neuropathy without further evaluation.

Comparison of surgical clipping and endovascular coiling in the treatment of oculomotor nerve palsy caused by posterior communicating artery aneurysm.

Oculomotor nerve palsy (ONP) caused by posterior communicating aneurysm (PcomAA) is mainly treated by surgical clipping or endovascular coiling. However, there are still some controversies about which treatment method could provide the more beneficial prognosis. This study aimed to compare ONP recovery rate between surgical clipping and endovascular coiling in patients diagnosed as PcomAA combined with ONP, and explore the potential risk factors of ONP recovery.The clinical data of 152 patients with ONP caused by PcomAA were retrospectively analyzed. Diameter of aneurysm, different treatment methods (surgical clipping or endovascular coiling), subarachnoid hemorrhage (SAH), degree of preoperative ONP, time from ONP onset to treatment, as well as degree of ONP symptom recovery were collected from medical records. All patients were followed up for at least 1 year.One hundred twelve patients underwent surgical clipping and 40 patients received endovascular coiling. There were no significant differences in age, gender, aneurysm diameter, hypertension, dyslipidemia, time from ONP symptom onset to treatment, SAH, and preoperative ONP degree between the 2 groups (all P > .05). Time to complete or partial recovery was 86.7 ±â€Š35.7 days for patients receiving surgical clipping and 132.6 ±â€Š37.5 days for patients receiving endovascular coiling, respectively (Log rank test, P < .001). The recovery rate was 94.6% in the surgical clipping group and 65.0% in the endovascular coiling group. The difference between the two groups was statistically significant (P < .001). Postoperative ONP recovery in the surgical clipping group was significantly superior to that of patients in the endovascular coiling group (HR, 2.625; 95% CI: 1.423-4.841; P = .002). Time from ONP symptom onset to treatment exerted the obvious effect on the ONP prognosis (HR, 0.572; 95% CI: 0.384-0.852; P = .006). In addition, the ONP recovery in patients with SAH before surgery was also independently associated with ONP prognosis (HR, 1.276; 95% CI, 1.043-1.562; P = .018). There was no treatment-related death in either group, and postoperative complications were within the manageable range.The recovery rate and recovery degree of ONP after surgical clipping was significantly better than that of endovascular coiling in PcomAA patients combined with ONP. The postoperative ONP recovery was associated with preoperative spontaneous SAH and time from ONP onset to treatment.

Management of Visual Dysfunction in Patients with Parkinson's Disease.

Parkinson's disease (PD) is a movement disorder with many symptoms responsive to treatment with dopamine agonists, anti-cholinergics and the dopamine precursor, levodopa. The cardinal features of PD include tremor, rigidity, bradykinesia, and postural instability. There also are non-motor features that include sleep disorders, cognitive and affective dysfunction, hyposmia, pain and dysautonomia (constipation, bloating, orthostasis, urinary symptoms, sexual dysfunction, dysphagia). Among these non-motor features are signs and symptoms of visual system impairment that range from subtle examination findings to those causing severe disability. In this review we describe common PD-related abnormalities in the visual system, how they present, and potential treatments.

The oculomotor neurovascular conflict: Literature review and proposal of management.

BACKGROUND: The Oculomotor nerve (OCN) lies in a close relationship with large arteries inside the basal cisterns. Therefore, it may be compressed by vascular malformations or aneurysms. Nevertheless, the compression is not always related to pathologic conditions. Indeed, some cases of neurovascular conflicts of the OCN have been described in the literature. METHODS: A case of neurovascular conflict of the OCN resolved after steroid treatment is reported. Additionally, a systematic literature review of those cases was performed. RESULTS: OCN palsy due to a neurovascular conflict has been described as acute or chronic persistent palsy, or with an intermittent presentation. Symptoms result from compression, although asymptomatic compression is not uncommon. Surgical treatment, pharmacological treatment, and observation have been reported as options in the literature. Microvascular decompression was employed effectively in some cases of OCN neurovascular conflict. Nevertheless, other cases were treated successfully with steroids (persistent presentation) and carbamazepine (intermittent presentation). A management algorithm based on the results of the literature review is proposed. CONCLUSIONS: Treatment options for OCN neurovascular conflicts and their results are heterogeneous. Based on the literature review, the pharmacological treatment seems to be the most appropriate first-line approach, reserving surgery for refractory cases. Collecting clinical information about new cases will allow defining treatment standards for this rare condition.

Endovascular versus surgical treatment for improvement of oculomotor nerve palsy caused by unruptured posterior communicating artery aneurysms.

BACKGROUND: There is no consensus regarding the best treatment option for unruptured aneurysms of the posterior communicating artery (PCom) presenting with oculomotor nerve palsy (ONP). We aimed to assess predictors of ONP recovery in a multicenter series of consecutive patients. MATERIALS AND METHODS: A retrospective review of prospective databases in three tertiary neurosurgical centers was carried out, selecting patients with ONP caused by unruptured PCom aneurysms, treated by surgical clipping or embolization, between January 2006 and December 2013. Patient files and imaging studies were used to extract ophthalmological assessments, treatment outcomes, and follow-up data. Predictors of ONP recovery during follow-up were explored using univariate and multivariate analyses. RESULTS: We identified 55 patients with a median ONP duration before treatment of 11 days (IQR 4.5-18); the deficit was complete in 27 (49.1%) and incomplete in 28 (50.9%) cases. Median aneurysm size was 7 mm (IQR 5-9). Twenty-four (43.6%) patients underwent surgical clipping and 31 (56.4%) embolization as the primary treatment. Overall, ONP improved in 40 (72.7%) patients and persisted/recurred in 15 (27.3 %). Surgery, interval to complete treatment <4 weeks, aneurysm recurrence during follow-up, and retreatment during follow-up were significantly correlated with ONP outcome in the univariate analysis. In the multivariate analysis, independent predictors of ONP improvement were interval to complete treatment <4 weeks (OR 5.15, 95% CI 1.37 to 23.71, p=0.015) and aneurysm recurrence during follow-up (OR 0.1, 95% CI 0.02 to 0.47, p=0.003). CONCLUSION: There was no significant difference in ONP recovery between surgical clipping and embolization. The best predictor for ONP recovery was timely, complete, and durable aneurysm exclusion.

In addition, Professor LIN combined the yuan-primary and luo-connecting acupoints combination method, theory of "removing the stagnation of blood and qi " and theory of root-stem and origin-end, etc. into the treatment of oculomotor nerve palsy, and achieved good results.

Isolated Oculomotor Nerve Palsy in Mild Traumatic Brain Injury.

BACKGROUND: Isolated oculomotor nerve palsy is rarely encountered after mild traumatic brain injury. It is difficult to offer patients accurate management strategies or prognostic assessments because only a few reports have described the management of oculomotor nerve palsy. METHODS: We performed a search for all clinical studies of isolated oculomotor nerve palsy after mild traumatic brain injury published up to July 9, 2019. We placed no restrictions on language or year of publication in our search, and we searched the following key words: traumatic brain injury, isolated oculomotor nerve palsy, mild head trauma, management, and prognosis. RESULTS: We identified 14 cases of isolated oculomotor nerve palsy after mild traumatic brain injury. In three cases, steroids were used to manage the oculomotor nerve palsy. Five patients who had underlying brain lesions underwent surgery, and seven patients were observed and followed up. The time to partial or complete resolution was 6.0 ± 5.3 mos with a range of 0.5-18 mos. CONCLUSIONS: This review includes a survey of surgical treatment for the management of traumatic brain injury that underlies oculomotor nerve palsies, steroid therapy to reduce related brain edema, and oculomotor rehabilitation with training eye movement behavior.

Acute Bilateral Oculomotor Nerve Palsy in an Adult Patient with Neisseria meningitidis.

A 69-year-old woman was admitted to our hospital with a fever, dizziness, and headache caused by Neisseria meningitidis. After ceftriaxone was administered, she suddenly developed bilateral oculomotor nerve palsy. Intra-orbital magnetic resonance imaging using appropriate sequences revealed that her bilateral third intracranial nerves were enlarged and enhanced. She achieved complete recovery by two months after additional short-term treatment with intravenous immunoglobulin and methylprednisolone. Although intracranial nerve disorders that result from bacterial meningitis are most frequently reported in children, it is noteworthy that it can also cause focal intracranial nerve inflammation with ophthalmoparesis in N. meningitidis infection in adults.

Isolated third nerve palsy with pupillary involvement resulting from carotid-cavernous sinus fistula: A case report.

RATIONALE: Isolated third nerve palsy with pupillary involvement caused by a posterior drainage carotid-cavernous sinus fistula (CCF) is relatively rare. Diagnosis of a posterior drainage CCF can often be delayed due to its unapparent congestive signs. PATIENT CONCERNS: Here, we present the case of a young male patient with right-sided CCF, who presented with right-side headache and partial third nerve palsy with pupillary involvement. The diagnosis was confirmed using time-of-flight magnetic resonance angiography (TOF-MRA) and digital subtraction angiography (DSA). DIAGNOSES: A right-sided CCF was detected, which was primarily supplied by the dural branch of the right middle meningeal artery and venous drainage into the right inferior petrosal sinus. INTERVENTIONS: The patient was treated with transarterial coil embolization. OUTCOMES: At 2 months, ride-side headache was significantly improved and ptosis and limited extraocular muscle movement were partially resolved. LESSONS: CCF might not always present with ocular congestion. Although uncommon, white-eye and painful third nerve palsy with pupillary involvement may be caused by a posterior drainage CCF.

Isolated Oculomotor and Abducens Nerve Palsies as Initial Presentation of Cavernous Sinus Tuberculoma: Case Report and Literature Review.

BACKGROUND: Central nervous system tuberculoma is the most severe manifestation of extrapulmonary tuberculosis with high mortality. Cavernous sinus tuberculoma (CST) is a very rare central nervous system tuberculoma with few cases reported in the literature. CASE DESCRIPTION: A 57-year-old woman was admitted to our clinic with acute diplopia and headache limited to the right side. There was no specific medical history except for migraine, depression, and anxiety, all of which were controlled by oral medications. Physical examination revealed ptosis and mydriasis in the right eye, which indicated right third and sixth cranial nerve palsies. Pituitary magnetic resonance imaging showed a right parasellar lesion at the cavernous sinus wall and ophthalmic nerve. Laboratory examinations and brain computed tomography scan showed negative findings. Initial differential diagnosis included meningioma, sarcoidosis, tuberculoma, and lymphoma. However, results of further studies, including blood and cerebrospinal fluid cultures and Mycobacterium tuberculosis DNA assay, were negative. Biopsy of the cerebral lesion was performed through the subfrontal approach, and histopathologic study confirmed CST. She was treated with a standard antituberculous regimen. After 12 months of follow-up, no cerebral or clinical findings were seen. CONCLUSIONS: CST is a rare presentation of M. tuberculosis, and the diagnosis is a difficult challenge. However, accurate diagnosis and timely treatment of CST can result in complete cure.
