RESUMO
PURPOSE: To compare rates of diagnosis of neuro-ophthalmic conditions across the Coronavirus Disease 2019 (COVID-19) pandemic with pre-pandemic levels. DESIGN: Multicenter, retrospective, observational study. PARTICIPANTS: Patients seen for eye care between March 11, 2019, and December 31, 2021. METHODS: A multicenter electronic health record database, Sight Outcomes Research Collaborative (SOURCE), was queried for new diagnoses of neuro-ophthalmic conditions (cranial nerve [CN] III, IV, VI, and VII palsy; diplopia; and optic neuritis) and new diagnoses of other ophthalmic conditions from January 1, 2016, to December 31, 2021. Data were divided into 3 periods (pre-COVID, pre-COVID vaccine, and after introduction of COVID vaccine), with a 3-year look-back period. Logistic regressions were used to compare diagnosis rates across periods. Two-sample z-test was used to compare the log odds ratio (OR) of the diagnosis in each period with emergent ocular conditions: retinal detachment (RD) and acute angle-closure glaucoma (AACG). MAIN OUTCOME MEASURES: Diagnosis rate of neuro-ophthalmic conditions in each study period. RESULTS: A total of 323 261 unique patients (median age 59 years [interquartile range, 43-70], 58% female, 68% White) across 5 academic centers were included, with 180 009 patients seen in the pre-COVID period, 149 835 patients seen in the pre-COVID vaccine period, and 164 778 patients seen in the COVID vaccine period. Diagnosis rates of CN VII palsy, diplopia, glaucoma, and cataract decreased from the pre-COVID period to the pre-vaccine period. However, the optic neuritis diagnoses increased, in contrast to a decrease in RD diagnoses (P = 0.021). By comparing the diagnosis rates before and after widespread vaccination, all eye conditions evaluated were diagnosed at higher rates in the COVID vaccination period compared with pre-COVID and pre-vaccine periods. The log OR of neuro-ophthalmic diagnosis rates across every period comparison were largely similar to emergency conditions (RD and AACG, P > 0.05). However, the log OR of cataract and glaucoma diagnoses were different to RD or AACG (P < 0.05) in each period comparison. CONCLUSIONS: Neuro-ophthalmic diagnoses had a similar reduction in diagnosis rates as emergent eye conditions in the first part of the pandemic, except optic neuritis. After widespread COVID-19 vaccination, all ophthalmic diagnosis rates increased compared with pre-pandemic rates, and the increase in neuro-ophthalmic diagnosis rates did not exceed the increase in RD and AACG diagnosis rates.

BACKGROUND AND PURPOSE: The etiological distribution of oculomotor nerve palsy has varied amongst the studies. This study aimed to define the clinical features and underlying etiologies of isolated oculomotor nerve palsy by recruiting patients from all departments in a referral-based university hospital. METHODS: The medical records of 672 patients who had a confirmed diagnosis of isolated oculomotor nerve palsy at all departments of Seoul National University Bundang Hospital, Seongnam, South Korea, from 2003 to 2020 were reviewed. A proportion of the etiology of isolated oculomotor nerve palsy was also compared with that of patients pooled from the previous studies that were searched on PubMed in May 2022. RESULTS: The most common etiology was microvascular (n = 168, 26.5%), followed by vascular anomalies (n = 110, 17.4%), neoplastic (n = 86, 13.6%), inflammatory (n = 79, 12.5%), idiopathic (n = 60, 9.5%) and traumatic (n = 53, 8.4%). Neurologists were mainly involved in the management of microvascular and inflammatory oculomotor nerve palsies whilst ophthalmologists mainly participated in the care of idiopathic, neoplastic and traumatic palsies. Neurosurgeons mostly took care of oculomotor nerve palsy due to vascular anomalies. CONCLUSIONS: The proportion of etiologies of isolated oculomotor nerve palsy may differ according to the specialties involved in the management. The results of previous studies on the etiological distribution of isolated oculomotor nerve palsy should be interpreted with this consideration.

Brucellosis, a zoonotic disease caused by Brucella species, poses a significant global health concern. Among its diverse clinical manifestations, neurobrucellosis remains an infrequent yet debilitating complication. Here, we present a rare case of neurobrucellosis with unusual presentations in a 45-year-old woman. The patient's clinical course included progressive lower extremity weakness, muscle wasting, and double vision, prompting a comprehensive diagnostic evaluation. Notable findings included polyneuropathy, elevated brucella agglutination titers in both cerebrospinal fluid and blood, abnormal EMG-NCV tests, and resolving symptoms with antibiotic therapy. The clinical presentation, diagnostic challenges, and differentiation from other neurological conditions are discussed. This case underscores the importance of considering neurobrucellosis in regions where brucellosis is prevalent and highlights this rare neurological complication's distinctive clinical and radiological features. Early recognition and appropriate treatment are crucial to mitigate the significant morbidity associated with neurobrucellosis.

BACKGROUND: Amyloidosis is a rare condition characterized by the abnormal deposition of amyloid proteins in various tissues and organs. While systemic amyloidosis has been well-documented, amyloid deposition in extraocular muscles is an exceptionally rare occurrence, with only 35 reported cases. This case report sheds light on the importance of considering amyloidosis in the differential diagnosis of patients presenting with proptosis and diplopia, which are often associated with thyroid eye disease. CASE PRESENTATION: A woman in her twenties sought medical attention due to a complaint of diplopia. Her ocular examination revealed almost normal findings except for exotropia and proptosis. Orbital magnetic resonance imaging displayed fusiform enlargement of nearly all eye muscles, a presentation typically observed in thyroid eye disease. However, despite corticosteroid therapy, her symptoms showed no improvement. Given the unusual lack of response to conventional treatment, and inhomogeneous enhancement of the muscle, an extraocular muscle biopsy was conducted. This biopsy yielded a unique finding-amyloid deposition within the muscle tissue. This discovery was particularly intriguing due to the extreme rarity of amyloidosis affecting extraocular muscles, with fewer than three dozen documented cases worldwide. CONCLUSION: This unique case underscores the critical need for a comprehensive approach to diagnosing patients with proptosis and diplopia. While these symptoms are commonly attributed to thyroid eye disease, it is essential to consider alternative diagnoses such as amyloidosis, especially when standard treatments fail to yield results. The discovery of amyloid deposition in the extraocular muscles, although exceedingly rare, emphasizes the significance of a thorough differential diagnosis. In conclusion, this case report highlights the importance of vigilance in clinical practice, encouraging ophthalmologists to explore less common diagnostic possibilities when faced with challenging cases. Further research and clinical investigation are warranted to better understand the mechanisms and potential treatments for amyloidosis affecting the extraocular muscles.

OBJECTIVE: Presentation of acute retrobulbar subperiostal hemorrhage (hematoma) in the course of delivery. The occurrence, possible threats and recommended methods of treatment are described. Introduction: Acute retrobulbar hemorrhage is always a serious condition. Even if not connected with other ocular trauma, it could cause permanent blindness. The reason is based on constriction of the eye, decreasing of the blood supply and thus disruption of the oxygen supply to sensitive retinal tissues. After a short time, these tissues start to deteriorate and lose their natural function. This event is often connected with exophthalmia and diplopia. The primary diagnostic procedure is to measure intraocular pressure (IOP). Even if the ideal diagnostic tools are not accessible, performing a lateral canthotomy (event. with inferior cantholysis) is recommended to relieve IOP in acute situations. Normal intraocular pressure is considered to be 8-21 mmHg. Case report: Our 29-year-old female patient was in the second stage of delivery and suddenly got retrobulbar hemorrhage, resulting in exophthalmia and diplopia. Her baby was delivered shortly after the event. The following delivery course was normal, including her perineum repair and puerperium. Our patient was fortunate because her visual acuity and IOP were normal. Therefore, we chose an observational treatment strategy. After 5 weeks, we noted successful disintegration of the hematoma and decreased exophthalmia and diplopia without other consequences. Conclusion: We described retrobulbar subperiostal bleeding in our patient in the course of delivery. We depicted possible threats that could result in blindness and described recommended methods of treatment. Even if such a situation is extremely rarely, we believe that knowledge of these guidelines could help medical professionals broaden their treatment options. This particularly occurs when a trained eye surgeon is not available.

Acute acquired comitant esotropia (AACE) is mainly characterized by sudden onset, accompanied by diplopia, without extraocular muscles paralysis or ocular motility disorders. In recent years, the incidence of AACE has been increasing, researchers have found that this phenomenon may be related to the widespread use of electronic devices and the increase in the number of people working from home during the COVID-19 pandemic. However, its neural mechanisms have not been fully elucidated. This article primarily reviews the latest developments in the diagnosis and treatment of AACE from the perspectives of etiology and treatment methods, aiming to provide direction for future in-depth exploration of the pathogenesis and treatment approaches of this disease.

PURPOSE: Evaluate and analyze the efficacy of inferior oblique belly transposition (IOBT) in treating adult patients with diplopia and small-angle hypertropia caused by mild to moderate inferior oblique overaction (IOOA) secondary to acquired superior oblique palsy (SOP). METHODS: Nine adult patients with diplopia and small-angle hypertropia associated with mild to moderate IOOA secondary to unilateral acquired SOP were included in the current retrospective study. All patients received the IOBT procedure between February 2019 and May 2023 at The Second People's Hospital of Jinan and were followed up for more than 6 months after the surgery. During the procedure, the belly of the inferior oblique muscle was fixed to the sclera at 5 mm posterior to the temporal insertion of the inferior rectus muscle. The following indicators were reviewed pre- and post-surgery: the vertical deviation (VD) in the primary position and in the Bielschowsky test, the fovea disc angle (FDA) of the affected eye, changes in IOOA, and diplopia. RESULTS: After IOBT, the VD in the primary position decreased from 7.22â³ ± 1.72â³ (range 4â³-10â³) to 1.22â³ ± 1.30â³ (range 0â³-3â³). The VD in the Bielschowsky test decreased from 13.00â³ ± 1.80â³ to 3.22â³ ± 1.09â³. The FDA decreased from 10.02° ± 3.34° to 6.26° ± 1.91°. The grade of IOOA was reduced from 2.00 (1.00, 2.00) to 0.00 (0.00, 1.00). All changes were statistically significant (P < 0.001 or P = 0.006). Diplopia was resolved completely for all patients. CONCLUSIONS: IOBT can effectively treat adults with diplopia and small-angle hypertropia caused by mild to moderate IOOA secondary to acquired SOP.

This is a case report describing an unusual presentation of acute painful diplopia that led to the diagnosis of VEXAS syndrome. VEXAS (Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic) syndrome is an adult-onset monogenic auto-inflammatory disease due to somatic UBA1 gene mutation in haematopoietic progenitor cells. Our patient was a 67-year-old diabetic male who presented with painful eye movements associated with diplopia, left periorbital pain and swelling. Imaging revealed an inflammatory process involving multiple intra- and extra-orbital structures. The patient improved initially with a short course of intravenous steroids. However, two months later he re-presented with right facial swelling. Bone marrow biopsy demonstrated UBA1 gene mutation supporting the diagnosis of VEXAS syndrome. This case highlights a unique ocular presentation of VEXAS.
RESUMO
Isolated paresis of the inferior rectus muscle (IRM) represents a rare occurrence. This case report involves a young adult male who, abruptly during a Valsalva maneuver, encountered acute vertical diplopia due to right IRM paresis, resolving spontaneously within a few hours. The patient presented without identifiable risk factors, and magnetic resonance imaging revealed a minor left thalamic ischemic lesion. A cardiac study identified the presence of a patent foramen ovale, potentially associated with a paradoxical embolism, indicating its likely role in this transient ischemic event.
RESUMO
Human immunodeficiency virus (HIV) and syphilis are two sexually transmitted diseases that continue to pose significant public health challenges globally. HIV and syphilis can be seen together; individuals with one of these infections are at risk of developing the other. Sharing common risk factors such as sexual transmission or intravenous drug use makes their coincidence likely. Syphilis, an infection caused by a spirochaete (Treponema pallidum), is a great mimicker and can present with a wide variety of clinical manifestations. Syphilis can cause various neurological symptoms including complete oculomotor nerve palsy; however, it is not a common manifestation. Here, we report for the first time a case of persistent incomplete oculomotor nerve palsy with pupillary involvement caused by the involvement of the inferior division of the oculomotor nerve, secondary to HIV and syphilis co-infection.
RESUMO
BACKGROUND AND PURPOSE: The etiologies of abducens nerve palsy have shown a large variability among studies. This study aimed to establish the clinical features and underlying etiologies of isolated abducens nerve palsy by recruiting patients from all departments in a referral-based university hospital. METHODS: We reviewed the medical records of 807 patients with a confirmed diagnosis of isolated abducens nerve palsy at all departments of Seoul National University Bundang Hospital, Seongnam, Republic of Korea, from 2003 to 2020. We also compared the proportion of etiology with that of the patients pooled from the previous studies. RESULTS: The most common etiology was microvascular (n = 296, 36.7%), followed by idiopathic (n = 143, 17.7%), neoplastic (n = 115, 14.3%), vascular anomalies (n = 82, 10.2%), inflammatory (n = 76, 9.4%), and traumatic (n = 35, 4.3%). Patients were mostly managed by ophthalmologists (n = 576, 71.4%), followed by neurologists (n = 479, 59.4%), emergency physicians (n = 278, 34.4%), neurosurgeons (n = 191, 23.7%), and others (n = 72, 8.9%). The proportion of etiology significantly differed according to the age and sex of the patients and the specialties involved in the management (p < 0.001). Compared to the pooled data from the previous reports, the current study showed a higher prevalence of microvascular cause but a lower occurrence of traumatic and neoplastic causes. CONCLUSIONS: The results of previous studies on etiologic distribution of isolated abducens nerve palsy should be interpreted with consideration of the demographic features of patients recruited and the specialties involved.

Facial intramuscular injections of Botulinum toxin (BoNT) injections are among the most common cosmetic procedures in dermatology. Rarely, serious adverse reactions such as blepharoptosis, diplopia and periorbital hematoma may occur with improper administration technique. Here we report a case of painless diplopia 5 weeks post-BoNT injection for 'crow's feet' likely due to inadvertent BoNT diffusion into the lateral rectus muscle causing a temporary palsy. This case aims to raise awareness of proper cosmetic BoNT injection techniques in the periorbital area to avoid ophthalmic complications.

PURPOSE: The present study aims to investigate how well CT images correlate to surgical findings in orbital floor fractures and to the presence of diplopia. METHODS: In this cross-sectional study, 27 consecutive patients already selected for surgery due to an orbital floor fracture underwent a routine CT scan (axial, coronal, sagittal). An ophthalmologist established any presence of diplopia. Extent of fracture/injury seen on CT was compared to that discovered during surgery. RESULTS: In the surgeons´ opinions CT-images were in concordance with surgical findings in 71% of the cases. Agreement for pure blow out fractures was high (92%). Tetrapod fractures as a cause of an orbital floor fracture was only identified as such by surgeons in three of 11 cases, all subjected to orbital exploration, not only a closed reduction. Diplopia showed a significant correlation to rounding of the inferior rectus muscle at coronal CT. "Rounding" significantly correlated with the presence of a floor defect, to herniation of soft tissues and to the volume of displaced tissue. CONCLUSIONS: The results imply that the joint professional interaction between neuroradiology and surgery is important and would benefit from the use of an easy and well-defined classification system of orbital floor fractures. In Sweden a national record to collect data on all zygomaticomaxillary complex fractures assessed is to be started aiming at making general statements possible by time.

Due to the precautions put in place during the COVID-19 pandemic, utilization of telemedicine has increased quickly for patient care and clinical trials. Unfortunately, teleconsultation is closer to a video conference than a medical consultation, with the current solutions setting the patient and doctor into an evaluation that relies entirely on a two-dimensional view of each other. We are developing a patented telehealth platform that assists with diagnostic testing of ocular manifestations of myasthenia gravis. We present a hybrid algorithm combining deep learning with computer vision to give quantitative metrics of ptosis and ocular muscle fatigue leading to eyelid droop and diplopia. The method works both on a fixed image and frame by frame of the video in real-time, allowing capture of dynamic muscular weakness during the examination. We then use signal processing and filtering to derive robust metrics of ptosis and l ocular misalignment. In our construction, we have prioritized the robustness of the method versus accuracy obtained in controlled conditions in order to provide a method that can operate in standard telehealth conditions. The approach is general and can be applied to many disorders of ocular motility and ptosis.

RATIONALE AND OBJECTIVES: Evaluate the implementation of an MRI scanner dedicated to emergencies on the management of patients admitted in the emergency department (ED) for binocular diplopia (BD). MATERIAL AND METHODS: This was a prospective non-interventional single-center study from February 2018 to February 2020. A total of 110 patients were included: 52 patients during the first stage (29 women; 23 men; mean age 65.2 years); 58 during the second stage (29 women; 29 men; mean age 51.4 years). Patients underwent an enhanced-CT examination in the first stage and an MRI examination in the second stage. Criteria used to evaluate the new management of patients were: proportion of patients with an imaging diagnosis explaining BD, turnaround time (TT), ED length of stay (EDLOS), hospital admission rate, hospital length of stay (HLOS), number of MRI examinations requested as a second procedure for the same indication and radiation doses. Descriptive statistics were used to present results with Student's test for quantitative variables and chi-square test for qualitative variables. RESULTS: Respectively 1 (1.92%) and 17 (29.31%) patients had definitive diagnosis in stages 1 and 2, with a significant difference in examination modalities (p=0.0001). The TT, EDLOS, hospital admission rate, and HLOS were not significantly different between the two stages. Radiation dose was significantly different between the two groups (p<0.05). CONCLUSION: Implementation of an MRI scanner dedicated to emergencies can improve the etiological diagnostic performance of binocular diplopia and reduce patient's exposure to ionizing radiation without increasing the average turnaround time or emergency department length of stay.

Accurate and timely diagnosis of posterior circulation ischemic stroke is a challenge for emergency neurology clinicians, even MRI scan which is believed to be sensitive to acute ischemic lesions may be negative. It is particularly important to obtain the typical or characteristic symptoms and signs of the patients through comprehensive physical examination. We report a case of posterior inferior cerebellar artery (PICA) territory infarction with "episodic postural diplopia" as the initial symptom, hoping that clinicians notice the vertical diplopia caused by the disfunction of otolith gravity conduction pathway, which is characterized by the degree of diplopia being affected by postural changes. A 44-year-old man was in hospital due to episodic postural diplopia for 4 months, dizziness and unstable walking for 5 days. In the past four months, the patient had endured episodic diplopia attack for 8 times when standing or walking, which could be relieved obviously while lying down and gradually disappeared within 5-10 minutes. He had not seen a doctor since the outbreak of the novel coronavirus. Five days before admission, diplopia worsened accompanying obvious vertigo, nausea and vomiting, left facial numbness, and hiccups. The diplopia could be relieved after taking the supine position, but not completely disappear as before. Physical examination showed a triad of ocular tilt response (OTR), namely static ocular rotation (SOT), skew deviation (SD) and head tilt (HT). And also subjective visual vertical (SVV) deviation was found. Those signs were considered for otolith gravity conduction system involvement. Combined with other clinical signs, such as Horner signs, crossed sensory disorders, ataxia, and MRI scan, it was easy to find the infarction was in the territory of the left PICA. The reasons for the patient's "episodic posi-tional diplopia" in the early stage of the disease were considered as follows: (1) the gravity was less affected in the supine position, the stimulation of the otolith gravity conduction pathway was reduced, so the degree of eye deviation was reduced in the supine position. (2) As an ischemic cerebrovascular disease, the patient experienced a process of transient ischemic attack (TIA) in the posterior circulation, the cerebral blood supply and the hypoperfusion of stenosis were increased after lying down, so the diplopia symptom disappeared. The upright-supine test was recommended for the patients with vertical diplopia. It was recommened to differentiate between otolith pathway involvement and diplopia caused by trochlear nerve palsy.

PURPOSE: To evaluate the clinical features, possible etiological reasons, and treatment results in children who developed acute acquired comitant esotropia (AACE) without strabismus in previous years. METHODS: Medical records of the patients who were diagnosed with AACE between July 2017 and June 2021 were retrospectively reviewed. The children with ocular and orbital pathology, hypermetropia > 2.00 diopters, and anisometropia > 1.00 diopters were not included in the study. Possible etiological factors that could cause esotropia, treatment results, motor, and sensory functions were investigated. RESULTS: The mean age at first admission, and the onset of AACE, was 8.8 ± 2.9 (4-13) years of three female (23.1%) and 10 male (76.9%) cases. The causes of AACE were determined to be occlusion of the eye due to corneal foreign body removal in one (7.7%), emotional stress in one case (7.7%), and excessive close work, on computer and smartphone screens in the other 11 cases (84.6%). Orthotropia was achieved in cases who underwent strabismus surgery (n = 10) and in cases using the prism (n = 2); except for one case, all (92.3%) achieved binocular single vision (100 s/arc stereopsis and fusion) after treatment, while there was no binocular single vision in any of the cases before treatment. CONCLUSIONS: Acute acquired comitant esotropia is a rare clinical entity. Successful motor and sensory outcomes can be achieved by strabismus surgery or by prism therapy. It is critical to investigate the patients with AACE in terms of intracranial pathologies, although rarely seen.

We present a case of a 50-year-old female who was diagnosed with an isolated right abducens nerve palsy and was found to have a persistent trigeminal artery (PTA). The trigeminal artery is the most common persistent embryological carotid-vertebrobasilar anastomosis. A PTA can be picked up as an incidental finding on magnetic resonance imaging (MRI) or angiography. It has been reported that a PTA can be found in 0.1 to 0.6% of all cerebral angiograms. PTA has been linked to several rare abnormalities such as vascular aneurysms and cranial nerve compression. Our patient presented with diplopia and was found to have a paresis of the right lateral rectus muscle consistent with a right abducens nerve palsy. MRI found a right-sided PTA indenting the ventral surface of the pons. This case investigates and highlights that neurovascular compression from a PTA can cause an isolated abducens nerve palsy. Further research is required to investigate if surgical intervention for non-aneurysmal PTA would be beneficial for patients.
RESUMO
Ischaemic optic neuropathy is the most common, feared, and recognised ocular manifestation of giant cell arteritis (GCA), while extraocular muscle palsy rarely occurs in the disease. Overlooking the diagnosis of GCA in aged patients with acquired diplopia and strabismus is not only sight- but also life-threatening. Here, we present, for the first time, a case of unilateral abducens nerve palsy and contralateral anterior ischaemic optic neuropathy as the presenting signs of GCA in a 98-year-old woman. Prompt diagnosis and treatment prevented further visual loss and systemic complications and allowed for rapid resolution of the abducens nerve palsy. We also aim to discuss the possible pathophysiological mechanisms of diplopia in GCA and to emphasise that acquired cranial nerve palsy must raise suspicion of this severe disease in elderly patients, particularly in association with ischaemic optic neuropathy.
