RESUMEN
RATIONALE: Amid the pervasive deployment of imidacloprid, the incidence of poisoning from this compound has risen markedly. Those afflicted with imidacloprid poisoning typically exhibit symptoms ranging from headaches, dizziness, nausea, and abdominal pain, to impaired consciousness and breathlessness, yet instances of ocular paralysis induced by this toxin have not previously been documented. PATIENT CONCERNS: When the pesticide spray inadvertently made contact with the patient's eyes, they were seared with a burning sensation and discomfort. Subsequent to this incident, on the second day, the individual began to experience diplopia in the right eye and found it arduous to elevate his eyelids, indicating a challenge in achieving full extension. DIAGNOSES: Based on the medical history, symptoms, and signs, the patient was diagnosed with oculomotor nerve palsy caused by imidacloprid. INTERVENTIONS: The treatment involved intravenous dexamethasone to reduce inflammatory response in the eye tissue; oral pantoprazole enteric-coated tablets to suppress acid production and protect the stomach; Xuesaitong administered intravenously to improve blood supply to the eye and promote metabolism of toxins; vitamin C, cobamamide, and vitamin B1 for nerve nutrition and antioxidant effects; local application of tobramycin-dexamethasone eye drops for anti-inflammatory purposes; and repeated flushing of the conjunctival sac with saline. Finally, the patient improved and was discharged. OUTCOMES: After active treatment, the patient finally improved diplopia and ptosis. LESSONS: This report marks the first documentation of oculomotor nerve palsy induced by imidacloprid, featuring diplopia, and blepharoptosis without substantial limitation of ocular motility. Following therapeutic intervention, the patient showed marked improvement and was discharged from the hospital, providing a point of reference for the treatment of analogous cases in future clinical practice. It also serves as a reminder for the public to take appropriate precautions when using imidacloprid.

BACKGROUND: This cohort study aims to examine the relationship between the occurrence of cranial nerve palsy (CNP) affecting the third, fourth, or sixth cranial nerve and the subsequent risk of stroke, with a particular focus on the modulating effect of age on this association. METHODS AND RESULTS: We established a cohort of individuals diagnosed with third, fourth, or sixth CNP who underwent national health screening within 2 years of diagnosis from 2010 to 2017. A control group was matched by sex and age at a ratio of 1:5. Participants were followed until December 31, 2019. We use multivariable Cox proportional hazards regression analyses to assess the association between ocular motor CNP and subsequent stroke stratified by age. Covariates including lifestyle, health behavior, underlying comorbidities, and Charlson comorbidity index score were also adjusted. Compared with the control group, the ocular motor CNP group had a higher risk of stroke after adjusting for potential confounders (hazard ratio [HR], 1.23 [95% CI,, 1.08-1.39]). The risk of stroke increased by 8.91 times in individuals with ocular motor CNP who were in their 30s (HR, 8.91 [95% CI, 1.63-48.66]). The risk increased by 2.49 times in those who were in their 40s, 1.78 times in those who were in their 50s, and 1.32 times in those who were in their 60s (HRs, 2.49, 1.78, and 1.32 [95% CI, 1.39-4.45, 1.31-2.42, and 1.08-1.62], respectively). However, for those who were in their 20s, 70s, or 80s, the incidence of stroke did not significantly increase. CONCLUSIONS: Our study establishes an association between ocular motor CNP and an increased risk of stroke, particularly in young adults.

BACKGROUND: Neurologically isolated ocular motor nerve palsies often present a management dilemma. Neuroimaging is more likely to be offered to patients <50 years without coexisting ischaemic risk factors as their risk of sinister underlying causes is thought to be higher. However, populations are rapidly ageing and advanced neuroimaging is now more widely available. We thus investigated the incidence of abnormal neuroimaging outcomes in the traditionally low-risk older patient group. METHODS: This is a retrospective cohort study of 353 patients presenting with isolated ocular motor nerve palsies to a tertiary neuro-ophthalmology service in Singapore over a four-year (2015 to 2019) period. Clinical data was obtained through manual review of case records. Common aetiologies, age-based differences in prevalence of causes and abnormal neuroimaging outcomes were statistically analysed. RESULTS: Abnormal neuroimaging outcomes were significantly greater in the younger cohort only when age segregation was performed at 60 years of age. In a multivariate analysis, acute onset rather than ischaemic risk factors were independently predictive of normal neuroimaging outcomes. After adjusting for prior cancer risk and clinical bias from presumed ischaemic palsies, abnormal neuroimaging outcomes were seen in 14.1% ≥ 50 yrs, 10.9% ≥ 60 yrs and 15.1% ≥ 70 yrs. CONCLUSIONS: In patients presenting with isolated ocular motor nerve palsies, acute onset may be a more reliable indicator of an ischaemic palsy rather than advanced age or presence of ischaemic risk factors. If onset is not acute, neuroimaging should be considered irrespective of age and coexisting ischaemic risk factors.

BACKGROUND: The aim of this systematic review is to identify cases of neurogenic ocular palsy in the presence of COVID-19 and to document patient characteristics, type of palsy and possible aetiologies. METHODS: A systematic search of PubMed, Medline and CINAHL databases was conducted on the 6th of January 2023 to identify cases of neurogenic ocular palsy in patients with current or previous COVID-19 infection. Data were pooled to summarise the neurogenic palsy, patient clinical characteristics and proposed palsy mechanisms. RESULTS: The combined database search yielded 1197 articles. Of these, 23 publications consisting of 25 patients met the inclusion criteria. Most patients were male (68%) and ranged in age from 2 to 71 years (median=32.7, SD=21.4). Seven patients (28%) were children aged 2 to 10 years old. Abducens palsies were most common (68%) and the most common ocular presentation was diplopia (76%) with an average time of onset 15 days from testing positive to COVID-19 or having symptoms of the virus. Proposed mechanism of development of a neurogenic palsy secondary to COVID-19 infection was classified into one of three categories: vascular/thrombotic, a viral neuro-invasive or inflammatory virus-mediated immune response. DISCUSSION: This study suggests that COVID-19 infection may be linked to oculomotor, trochlear and abducens nerve palsies and the underlying mechanisms may vary but are difficult to definitively establish. Further studies investigating the onset of neurogenic palsy secondary to COVID-19 infection is required.

Patients with inflammatory bowel disease (IBD) may present with extraintestinal manifestations. Neurological symptoms associated with IBD are infrequent. Thus, any unexplained neurological symptom that occurs in patients with IBD should raise the suspicion of a link between the two disorders. We report a case of a man in his 60s, who was diagnosed with Crohn's disease and developed ptosis and diplopia. Neurological examination revealed oculomotor nerve palsy, sparing the pupil. MRI and magnetic resonance angiography of the brain were insignificant and no other cause was determined. He was treated with oral corticosteroids and symptoms gradually subsided. Cranial nerve palsies associated with IBD have been rarely reported. They usually involve the optic and acoustic nerve and are attributed to a common dysimmune base. This is the first reported case of oculomotor nerve palsy (III cranial nerve) associated with IBD. Clinicians treating patients with IBD should be alert for unusual neurological complications and treat them appropriately.

We report a case of a previously healthy man in his 40s who presented with mild SARS-CoV-2 infection (COVID-19) concomitant with acute onset of left third cranial nerve palsy with restricted supraduction, adduction and infraduction. Our patient did not present any history of hypertension, hyperlipidaemia, diabetes mellitus or smoking. The patient recovered spontaneously without any antiviral treatment. To our knowledge, this is the second report of third cranial nerve palsy spontaneously resolved without any risk factors of vascular disease, specific image findings, nor any possible causes other than COVID-19. In addition, we reviewed 10 other cases of third cranial nerve palsy associated with COVID-19, which suggested that the aetiology varies greatly. As a clinician, it is important to recognise COVID-19 as a differential diagnosis for third cranial nerve palsy. Finally, we aimed to encapsulate the aetiologies and the prognosis of the third cranial nerve palsy associated with COVID-19.

OBJECTIVES: To describe the etiologies of binocular diplopia for patients presenting to the ophthalmologic emergency department of the Regional University Center Hospital (CHRU) of Tours. METHODS: This is a retrospective study of the medical records of patients who presented with binocular diplopia in the ophthalmic emergency department of the CHRU of Tours between January 1st and December 31st, 2019. Binocular diplopia was classified as paralytic or non-paralytic according to the ocular motility examination. RESULTS: One hundred twelve patients were included. The median age was 61 years. Internal referral from other hospital services represented 44.6% of the patients. On ophthalmological examination, 73.2% had paralytic diplopia, 13.4% non-paralytic diplopia and 13.4% normal examination. Neuroimaging was performed in 88.3% of cases, with 75.7% of patients receiving it on the same day. Oculomotor nerve palsy was the most frequent cause of diplopia in 58.9%, the majority represented by abducens nerve palsy (60.6%). The most frequent etiology of binocular diplopia was ischemic, with microvascular damage in 26.8% of cases and stroke in 10.7% of cases. CONCLUSION: Among patients assessed in an ophthalmological emergency department setting, one in ten patients had stroke. It is essential to inform patients of the urgent nature of ophthalmological evaluation in the case of acute binocular diplopia. Urgent neurovascular management is also mandatory and should be based on the clinical description provided by the ophthalmologist. Neuroimaging should be performed as soon as possible, based on the ophthalmologic and neurological findings.

BACKGROUND: Oculomotor nerve palsy is a common and well-described disease with diverse etiologies. Clinicians should quickly and correctly diagnose and treat oculomotor nerve palsy according to its characteristics and the accompanying symptoms and signs. Intracranial aneurysm is an important and frequent cause of oculomotor nerve palsy. Considering the catastrophic consequences of rupture, the possibility of an urgent, life-threatening disease should always be considered. CASE PRESENTATION: A 63-year-old Chinese woman presented with intermittent left ptosis and diplopia and painless incomplete oculomotor nerve palsy without pupil involvement. She manifested no mydriasis or extraocular muscle weakness, and the light reflex was normal. Other cranial nerves and somatosensory and somatomotor examinations were normal. The neostigmine experiment and electromyography were normal, so the diagnosis of myasthenia gravis was excluded. Brain magnetic resonance angiography showed a 4-mm aneurysm located at the cavernous segment of the left internal carotid artery. Unfortunately, the patient refused digital subtraction angiography and was discharged home without further treatment. CONCLUSION: Neuroimaging must be performed to exclude intracranial aneurysms in oculomotor nerve palsy regardless of whether the pupils are involved, as aneurysm rupture carries substantial morbidity and mortality.

OBJECTIVE: To quantify changes in ductions following nasal transposition of the split lateral rectus muscle (NTSLR) for treating third nerve palsy. DESIGN: Retrospective cohort study. PARTICIPANTS: A single eye from each patient with third nerve palsy treated with NTSLR with ocular motility measurements. METHODS: Observation of changes in pre- and postoperative ductions. Outcome measures including patient demographic and surgical factors associated with the ability to adduct beyond the midline after NTSLR were evaluated using multivariable logistic regression. RESULTS: A total of 116 patients met the inclusion criteria for this study. The NTSLR significantly decreased abduction (median of 0 limitation [interquartile range (IQR), 0-0] prior to surgery to -4 [IQR, -4 to -3] after NTSLR; p < 0.001), with a corresponding improvement in adduction (median, -5 [IQR, -5 to -4] prior to surgery to -4 [IQR, -4 to -3] after NTSLR; p < 0.001). There was no change in median supraduction or infraduction after NTSLR (p > 0.05). The ability to adduct beyond the midline after NTSLR was demonstrated in 42% of patients. Although not statistically significant, a trend toward a postoperative ability to adduct beyond the midline was seen in patients who had concurrent superior oblique muscle tenotomy (odds ratio [OR]â¯=â¯5.08; 95% CI, 0.91-40.9) or who were designated with partial rather than complete third nerve palsy (ORâ¯=â¯2.29; 95% CI, 0.82-6.70). CONCLUSIONS: NTSLR improves the horizontal midline positioning of eyes with third nerve palsy. Most eyes lose the ability to abduct, but some regain a modest ability to adduct while vertical ductions remain unchanged.

BACKGROUND: Traumatic brain injury (TBI) is one of the common causes of ocular motor nerve (oculomotor nerve [CN3], trochlear nerve [CN4], and abducens nerve [CN6]) palsies, but there has been no large study of ocular motor nerve palsy caused by TBI. This study aimed to investigate the characteristics of and differences in ocular motor nerve palsy after TBI, according to patient age and severity of TBI. METHODS: This was a population-based retrospective cohort study that included patients who had ocular motor nerve palsy after TBI with ≥6 months of continuous enrollment using claims data from the IBM MarketScan Research Databases (2007-2016). We assessed sex, age at the first diagnosis of TBI, the severity of TBI, and the rates of strabismus procedures according to the age and severity of TBI. The rates of muscle transposition surgery and chemodenervation in CN3, CN4, and CN6 palsy were investigated. RESULTS: A total of 2,606,600 patients with TBI met the inclusion criteria. Among them, 1,851 patients (0.071%) had ocular motor nerve palsy after TBI. The median age of the patients was 39 (Q1-Q3: 19-54) years, and 42.4% of the patients were female. The median continuous enrollment period after the first diagnosis of TBI was 22 (Q1-Q3: 12-38) months. Of the 1,350,843 children with TBI, 454 (0.026%) had ocular motor nerve palsy. Of the 1,255,757 adults with TBI, 1,397 (0.111%) had ocular motor nerve palsy. Among these 1,851 patients, CN4 palsy (697, 37.7%) occurred most frequently, and strabismus procedures were performed in 237 patients (12.8%). CN6 palsy developed most frequently in children. More children (16.5%) underwent strabismus surgeries than adults (11.6%) ( P = 0.006). The proportion of CN4 palsy (52.3%) was higher while the proportion of CN3 palsy (15.5%) was lower in patients with mild TBI than in patients with moderate-to-severe TBI ( P < 0.001). CONCLUSIONS: CN4 palsy developed most frequently among patients of all ages, and only approximately 13% of the patients underwent strabismus procedures for ocular motor nerve palsy after TBI. The rate of development of ocular motor nerve palsy was approximately 4.3 times lower in children than adults, and children most frequently had CN6 palsy after TBI.

Midbrain strokes are rare and are usually accompanied by other concomitant injuries. The simultaneous presence of ipsi and contralateral signs makes it necessary to think of a brainstem syndrome due to involvement of the brainstem. Magnetic nuclear resonance is the study of choice to characterize and locate the lesion. We report the case of a 71-year old man who presented right third cranial nerve palsy and hemiataxia, a rare condition known as Claude's syndrome.
Los accidentes cerebrovasculares mesencefálicos son poco frecuentes y por lo general están acompañados de otras lesiones concomitantes. La presencia simultánea de signos ipsi y contralaterales obliga a pensar en un síndrome alterno por compromiso del tronco encefálico. La resonancia magnética nuclear es el estudio de elección para caracterizar y localizar la lesión. Presentamos el caso de un hombre de 71 años que sufrió parálisis del tercer par derecho y hemiataxia izquierda, cuadro infrecuente, conocido como síndrome de Claude.

Oculomotor nerve palsy following traumatic brain injury is a rare entity. A head injury can result in diffuse neuronal axonal injury with subsequent microbleed within the nerve tissue. We report an unusual case of a patient who presented with complete isolated right third nerve palsy following a road traffic accident. In this patient, magnetic resonance imaging (MRI) revealed swelling and edema of the right oculomotor nerve along its cisternal segment with contrast enhancement. The acquisition of susceptibility-weighted images on MRI helped to clinch the diagnosis of intraneural hemorrhage as a cause of post-traumatic oculomotor nerve palsy.

PURPOSE: To evaluate new-onset strabismus in adults presenting to an ophthalmic emergency department, and to identify which patients require neuroimaging. METHODS: This was a retrospective review of electronic medical records of patients 18 years and older who presented to an ophthalmic emergency department between January 1, 2019 and December 31, 2020 with new-onset strabismus. Data regarding demographics, causes, neuroimaging, and resolution were recorded and analyzed. RESULTS: Of the 557 patients in the current study, 54.8% were men and the mean age was 57.3 ± 16.7 years (range: 18 to 92 years). Most patients (72.4%) presented with diplopia. Esotropia was the most common ocular misalignment (43.6%) and was more common in women than men (51.6% vs 37.0%, respectively) (P = .001). The most common diagnoses were cranial nerve palsies (66.8%) for both sexes and all age groups, with the most common etiology being microvascular (48.1%) for patients 50 years and older and idiopathic (20.1%) for patients between 18 and 49 years old. The incidence of cranial nerve palsies was significantly higher in older patients (P < .001). Neuroimaging was performed in 58% of patients (n = 323), of whom 37.2% (n = 120) had abnormal findings. The most common abnormal neuroimaging finding was mass for all age groups and sexes (19.2%). Patients with cranial nerve palsy and microvascular etiology had a significantly lower proportion of abnormal neuroimaging findings (P < .001). CONCLUSIONS: Most cases of new-onset strabismus in adults presenting to the emergency department were due to cranial nerve palsy, particularly in older patients. Despite high rates of neuroimaging, patients with cranial nerve palsy had mostly normal findings. The current study supports the belief that neuroimaging may be deferred in patients older than 50 years with micro-vascular risk factors. [J Pediatr Ophthalmol Strabismus. 2022;59(4):269-273.].

Oculomotor nerve schwannomas are rare benign cranial nerve tumors. There are only a limited number of reports on this pathology in the literature, and there are currently no established management guidelines that aid providers in deciding on surgical versus nonsurgical management. We assess the published literature on the topic to identify indications for treatment as well as outcome measures (e.g., local control rates, survival rates, and complication rates) that have been reported as associated with the various treatment modalities. We attempt to develop an algorithm for evaluation and treatment of oculomotor nerve schwannomas in order to establish consensus on how these tumors should be treated.
