Abstract
PURPOSE OF REVIEW We set out to describe efferent neuro-ophthalmological complications that have been reported in association with coronavirus disease 2019 (COVID-19) infection. We describe syndromes affecting ocular motility and elaborate on mechanisms of disease, including para-infectious inflammation, hypercoagulability, endothelial damage, and direct neurotropic viral invasion. Despite global vaccination programs, COVID-19 continues to pose an international threat that may rarely result in diplopia or nystagmus. RECENT FINDINGS Efferent complications include cranial nerve palsies leading to diplopia, either isolated or in association with Miller Fisher syndrome. Nystagmus has been observed in the setting of hemorrhagic acute necrotizing encephalopathy and brainstem infarcts, and opsoclonus syndrome has been described. SUMMARY Observed neuro-ophthalmic associations need to be confirmed through larger comparative studies. Meanwhile, the range of possible complications should be recognized by neurologists and ophthalmologists alike, to facilitate faster diagnosis and treatment of both COVID-19 and its neuro-ophthalmic manifestations.

Abstract
Purpose To assess if ocular motility impairment, and the ensuing diplopia, after Baerveldt Glaucoma device (BGI) implantation, is related to the presence of a large fluid reservoir (bleb), using Magnetic Resonance Imaging (MRI). Methods In a masked observational study (CCMO-registry number: NL65633.058.18), the eyes of 30 glaucoma patients with (n = 12) or without diplopia (n = 18) who had previously undergone BGI implantation were scanned with a 7 Tesla MRI-scanner. The substructures of the BGI-complex, including both blebs and plate, were segmented in 3D. Primary outcomes were a comparison of volume and height of the BGI-complex between patients with and without diplopia. Comparisons were performed by using an unpaired t-test, Fisher’s Exact or Mann-Whitney test. Correlations were determined by using Spearman correlation. Results The median volume and height of the BGI-complex was significantly higher in patients with compared to patients without diplopia (p = 0.007 and p = 0.025, respectively). Six patients had an excessively large total bleb volume (median of 1736.5mm3, interquartile range 1486.3–1933.9mm3), four of whom experienced diplopia (33% of the diplopia patients). Fibrotic strands through the BGI plate, intended to limit the height of the bleb, could be visualized but were not related to diplopia (75% versus 88%; p = 0.28). Conclusions With MRI, we show that in a significant number of diplopia cases a large bleb is present in the orbit. Given the large volume of these blebs, they are a likely explanation of the development of diplopia in at least some of the patients with diplopia after BGI implantation. Additionally, the MR-images confirm the presence of fibrotic strands. As these strands are also visible in patients with a large bleb, they are apparently not sufficient to restrict the bleb height.

Abstract
PURPOSE To evaluate the efficacy and safety of inferior oblique muscle transposition and myopexy in patients with mild/moderate inferior oblique muscle overaction, with or without diplopia. METHOD We retrospectively analysed data for the 12 patients who underwent the technique. Data were collected from October 2018 to September 2021. Surgery was performed by suturing the inferior oblique belly to the sclera at 5 mm posterior to the temporal end of the inferior rectus. All 12 patients had mild hypertropia (≤6 prism diopters [pd]) in primary position and mild/moderate inferior oblique overaction. Mean preoperative hypertropia was 4.42 pd ± 1.62. Diplopia was recorded in 10 cases. The diagnoses were fourth nerve paresis (9), unilateral primary inferior oblique overaction (2) and dissociated vertical deviation (1). Torticollis was observed in 7 cases, 2 had subjective torsion and 2 objective torsion. RESULTS Mean age was 46.86 ± 25.1 years (50%: men). Diplopia resolved in 9 of the 10 cases. The mean final vertical deviation was 1.5 ± 2.93 (p = 0.001) pd in straight gaze. Of 7 mild overshoot in adduction, it disappeared in 3 and 4 remained the same. Of 5 moderate overshoot in adduction, 2 improved to mild and 3 disappeared. Torticollis was eliminated in 5 patients and improved in another 2. Mean time from surgery was 14.08 ± 8.05 months. There were no overcorrections. CONCLUSIONS Inferior oblique muscle transposition with myopexy is a safe and effective procedure in patients with mild-to-moderate inferior oblique muscle overaction and small-angle hypertropia, with or without diplopia.

Abstract
PURPOSE To evaluate the clinical effectiveness and safety of bioresorbable implants for treating paediatric zygomaticomaxillary complex (ZMC) fractures with concomitant orbital floor defects. METHODS A retrospective review of paediatric patients who underwent ZMC repair with concomitant orbital floor fractures with bioresorbable implants in Shanghai Ninth People's Hospital from July 2015 to June 2019 was performed. The primary outcome measures included ocular motility, diplopia, enophthalmos, facial deformities, and restricted mouth opening, as well as complication rates. Pre- and post-operative computed tomography scans were obtained for clinical diagnosis and surgical effectiveness. RESULTS Twenty two children were included in this study. Facial deformities were corrected in all 22 cases by surgical reconstruction postoperatively, and the average relative distance of Portals point-Zygomaxillare and Anteriornasalspine-Zygomaxillare were 1.3 ± 0.6mm ( P = 0.22) and 1.2 ± 0.5mm ( P = 0.19). The eye movement restored to normal in 13 patients. The mean amount of relative enophthalmos was 1.0 ± 0.4 mm ( P = 0.12). 12 cases had complete resolution of diplopia postoperatively at the extremes of the gaze, and 1 case presented persistent diplopia on the down gaze as before, but from level III to level I. Facial numbness was resolved completely in 6 cases, and 2 cases presented with persistent numbness but relieved significantly. The average Hounsfield units of RapidSorb plates and OrbFloor PI were 154 ± 5 and 99 ± 4 respectively on computed tomography image obtained 1 week postoperatively, which showed no obvious difference compared with 0.5 year postoperatively ( P > 0.1). Hounsfield units of implants gradually declined around 1 year postoperatively. Hounsfield units of RapidSorb plates (20 ± 1) were consistent with periorbital tissue during postoperative 2-year follow-up, and Hounsfield units of OrbFloor PI (19 ± 1) were consistent with periorbital tissue during postoperative 1.5-year follow-up. No patients had severe sequelae or implant related complications postoperatively. None of bone nonunion, malunion, infection or rejection occurred during the follow-up periods. CONCLUSIONS Open reduction and internal fixation for the treatment of ZMC fracture have achieved significant improvement in functional and cosmetic outcomes postoperatively. Bioresorbable materials have been proved to be effective and safe in the treatment of children's ZMC and orbital wall fractures.

Abstract
PURPOSE To describe the common causes of symptomatic strabismus and treatment required to resolve diplopia in adult patients seen by one orthoptist. PATIENTS AND METHODS Retrospective cross-sectional study of consecutive adult patients 18 years or older seen by one orthoptist over a 3-year period with a chief complaint of double vision. RESULTS Two hundred twenty-four consecutive adult patients were examined by the author. Chief complaint was double vision, followed by blurred vision, monocular diplopia, and eye strain. Past ocular histories were significant for early-childhood strabismus in 23 patients. Amblyopia was identified in five patients. Hypertension was a medical risk factor most associated with symptomatic strabismus. Cranial nerve paresis was the most common cause of the strabismus followed by benign, age-related divergence insufficiency esotropia. Prism was the most common treatment in 53% of patients followed by Bangerter foil occlusion in 44 patients (20%). Strabismus surgery was recommended in 11 patients (5%). Manifest refraction was successful in resolving symptoms of binocular diplopia in nine heterophoric patients (5%). Opaque pirate style occlusion was not used for any patient in this series. CONCLUSIONS Symptomatic acquired esotropia was a common type of strabismus encountered by the author and trochlear nerve paresis a common cause of symptomatic strabismus in this retrospective cross-sectional study. Press-On™ or ground-in spectacle prism of 12 prism diopters or less resolved diplopia in 124 patients (55%).

Abstract
RATIONALE GBS and MFS have been divided into several subtypes, constituting a series of independent and overlapping syndromes that share similar pathophysiology, leading to common clinical features, including history of previous infection, single-phase course, symmetry, skull or limbs weakness, CFS albumin cell separation (high protein, normal cell count), antiganglioside antibodies and axon, or evidence of demyelinating neuropathy neurophysiology. Part of the MFS in patients with clinical manifestations may be complicated, and even symptoms are not typical. A few patients may overlap with BBE or GBS. PATIENT CONCERNS Most patients with MFS/GBS overlap syndrome have a good prognosis, and a few patients may experience fluctuations or re-exacerbations. In most patients, after treatment, their neurological function basically recovers within a few weeks or months. DIAGNOSIS INTERVENTIONS The patient had ophthalmoplegia, ataxia, weak force, and protein-cell separation in cerebrospinal fluid during the development of the disease. The diagnosis of MFS overlapped with typical GBS was considered. The CSF specific IgG oligoclonal zone and anti-Sulfatide antibody were positive. Anti-GT1a IgG was positive. Anti-GQ1b IgG was positive, which supported the diagnosis of GBS spectrum disorders. According to their common immunological basis, plasma exchange or intravenous immunoglobulin (IVIG) therapy is recommended, which can effectively improve the symptoms and shorten the course of the disease. OUTCOMES After treatment with glucocorticoids and gamma globulin, the symptoms improved and the patient was discharged. LESSONS MFS/GBS Superimposed syndrome is a rare clinical disease. Therefore, more attention should be paid to early diagnosis and treatment of similar patients to avoid misdiagnosis. Cerebral spinal fluid (CFS) examination, neuroelectrophysiology, and GQ1b antibody detection can be used to confirm the diagnosis.

Abstract
PURPOSE To report five cases of ocular neuromyotonia in children and adolescents following radiation therapy for a variety of pediatric brain tumors. Notably, three cases occurred in children younger than 11 years. METHODS Case series of five patients with ocular neuromyotonia following proton beam therapy or conventional radiation. RESULTS Five cases of ocular neuromyotonia were identified following radiation treatment of various pediatric brain tumors. Onset ranged from 5 to 142 months after radiation treatment. The abducens nerve/lateral rectus muscle was affected in three patients, and the trochlear nerve/superior oblique muscle was affected in two patients. Ages at symptom presentation were 4 years (intermittent head tilt), 9 years (intermittent blurry vision and head tilt), 10 years (intermittent blurry vision progressing to intermittent diplopia), 15 years (intermittent diplopia), and 17 years (intermittent diplopia). One patient improved with gabapentin. Two patients experienced spontaneous resolution. One patient died due to meta-static disease, and one patient has planned follow-up. CONCLUSIONS Ocular neuromyotonia occurs most commonly following radiation to the brain and skull base. Clinicians need to be aware that ocular neuromyotonia presents differently in children (who may not report diplopia) than in adults or adolescents (who typically report diplopia). Two children in this series never reported diplopia, only intermittent head tilt and blurry vision. Ocular neuromyotonia requires a high index of suspicion to diagnose, especially in children. Membrane stabilizers can be used effectively, but observation may be a valid option in children because spontaneous resolution was seen. [J Pediatr Ophthalmol Strabismus. 2022;59(5):338-343.].

Abstract
A 30-year-old male presented with diplopia 1 month after implantation of an orbital floor plate for a blowout fracture. The orbital plate was removed 3 months later, however, the fixation bar was left in place as it had migrated full thickness through the inferior oblique muscle, sclera, choroid, and retina. After 5 years of head tilt, the patient was referred to our department with a metallic intraocular foreign body visible in fundo and an important elevation deficit. CT imaging confirmed our clinical suspicion of a retained fixation bar. The extraocular part of the fixation bar was removed via a transconjunctival inferior orbitotomy, leaving the intraocular part in place due to the high risk of ocular complications upon removal. Postoperative ocular motility improved greatly and the patient no longer experiences diplopia in daily life. Orbital plate migration is a rare complication that should be considered in de novo diplopia after orbital reconstruction.

Abstract
PURPOSE Orbital fractures are common facial fractures that can be challenging to repair and require careful attention to avoid unacceptable ophthalmic complications. Customized implants that are unique to an individual patient, or patient-specific implants (PSIs), have been increasingly used to repair orbital wall fractures. This systematic review summarizes the current evidence regarding custom-made orbital wall implants. METHODS A keyword search of published literature from January 2010 to September 2021 was performed using Ovid MEDLINE, PubMed, and the Cochrane Library databases. Original articles that included more than 3 human subjects with an orbital fracture repaired with a PSI were included. The search results were reviewed, duplicates were removed and relevant articles were included for analysis. RESULTS Fifteen articles meeting the inclusion criteria. The articles were categorized into 3 separate groups based on the method of PSI fabrication: manual molding of a PSI on a 3D-printed orbital model (53%), directly from a 3D printer (27%), or via a template fabricated from a 3D printer (20%). Three primary postoperative outcomes were assessed: rates of diplopia, enophthalmos, and orbital volume. Postoperative rates of diplopia and enophthalmos improved regardless of the PSI technique, and postoperative orbital volumes were reduced compared with their preoperative state. When PSIs were compared to conventional implants, patient outcomes were comparable. CONCLUSIONS This review of existing PSI orbital implant literature highlights that while PSI can accurately and safely repair orbital fractures, patient outcomes are largely comparable to orbital fractures repaired by conventional methods, and PSI do not offer a definitive benefit over conventional implants.

Abstract
We describe a case with torsional deviation of the eyes from a brainstem lesion. Torsional eye movement refers to changes in the position of the eyes in the roll plane around the visual axis. When the head is tilted laterally (that is, rolled toward the shoulder), the eyes roll in the opposite direction as part of the torsional vestibulo-ocular reflex known as the ocular counter-roll. Pathologies that affect the otolith-ocular pathway can lead to a torsional deviation of the eyes as part of the ocular tilt reaction (OTR) that also causes vertical deviation of the eyes (skew deviation) and head tilt. Lesions caudal to the pontomedullary junction (such as the labyrinth, eighth cranial nerve, or vestibular nucleus) result in an OTR with ipsiversive torsional deviation, whereas lesions rostral to the junction result in an OTR with contraversive torsional deviation. Furthermore, torsional deviation of the eyes in the OTR is conjugate (incyclotorsion in the higher eye and excyclotorsion in the lower eye), whereas torsional deviation from ocular palsy in peripheral lesions is disconjugate (e.g., exyclotorsion only in the higher eye with superior oblique palsy). Therefore, the pattern of torsional eye deviation can be helpful in localizing the lesion. Several techniques including fundus photography, double Maddox rod testing, optical coherence tomography, and video-oculography are used to measure torsional eye position.

Abstract
BACKGROUND AND OBJECTIVE Cranial nerve schwannomas almost always arise from sensory or mixed nerves. Motor cranial nerves, such as the trochlear nerve, are rarely associated with schwannomas. No consensus has yet been made for surgical intervention because of the low number of reported cases of trochlear nerve schwannomas. This study comprises a systematic review of the literature and our experience for surgically treated trochlear nerve schwannomas. METHODS Three databases (Web of Science, PubMed, and Cochrane Library) were searched without date restrictions. Studies were included if they were published in the English literature and presented patients of any age who underwent surgical treatment for trochlear schwannoma. Data extracted from the included studies were combined with our experience. RESULTS Forty-one studies, presenting 43 patients, met the inclusion criteria. The total number of patients was 45 after our experience was added. The most common symptoms were diplopia (62.2%), headache (46.7%), and motor weakness (37.8%). Mean age during the diagnosis was 45.1 years. Although the subtemporal transtentorial approach (n = 14) is the most preferred method, its application has decreased in recent years. In the last decade, the lateral suboccipital approach (n = 11) has gained popularity. Residual postoperative trochlear nerve deficit was detected in 81% of patients. The probability of neurologic deficit was not statistically associated with tumor volume (P = 0.914), location (P = 0.669), or resection rate (P = 0.554). CONCLUSIONS Although trochlear schwannomas are rare and their treatment involves challenges, total resection with the proper approach provides the most desirable results.

Abstract
ABSTRACT A 69-year-old man with a history of pontine hemorrhage 2 years ago noticed binocular vertical diplopia after the stroke. On examination, there was a small-angle incomitant left hyperdeviation that did not fit the 3-step test for fourth nerve palsy and incyclotorsion of the higher eye. On motility testing, there was an obvious pendular nystagmus. Resting tremor of the right hand was noticed on neurological examination. Examination of the oropharynx revealed rhythmic oscillations of the soft palate synchronous with the eye oscillations and hand tremor. These findings established a diagnosis of oculopalatal myoclonus (OPM). Although OPM is a well-described entity, this case is unique because the patient was completely asymptomatic from OPM and did not complain of oscillopsia but was very bothered by vertical diplopia because of skew deviation. It also demonstrates that OPM may coexist with skew deviation because anatomically vestibulo-ocular pathway is close to the triangle of Guillain-Mollaret and patients with lesions in one pathway should be examined for abnormalities in the other. Finally, it reminds us about the importance of monitoring patients with a history of brainstem insults for emergence of synchronous tremors years later and that simple maneuver-like ex/amining oropharynx may provide a clear diagnosis.

Abstract
A 36-year-old female patient presented to our clinic with a two months history of diplopia and dizziness. The symptoms appeared gradually and increased in frequency and intensity. She had no significant medical history and she did not take any medication. A full ophthalmological consult was performed, which revealed restricted ocular motility in the left eye (LE), in left gaze. Otherwise, the examination showed no pathological findings: best corrected visual acuity (BCVA) both eyes (OU) 1 (Snellen chart), normal slit lamp examination and pupillary reflexes, normal intraocular pressure (IOP) and fundus aspect. Diplopia tests revealed a horizontal diplopia, exacerbated in left gaze. Sixth nerve palsy suspicion was raised and the patient was directed to the neurology department. Following magnetic resonance imaging, with angiographic sequence, a complex intracerebral vascular malformation that interacted with the cranial nerves and determined horizontal diplopia, was found. For a correct diagnosis, we needed a good collaboration between various medical specialties, especially ophthalmology and neurology, because patients with diplopia often present for the first time at the ophthalmologist. Abbreviations: BCVA = best corrected visual acuity, IOP = intraocular pressure, LE = left eye, RE = right eye

Abstract
PURPOSE To evaluate the demographic details, clinical presentation, and surgical outcomes in patients presenting with strabismus following orbital wall fractures. METHODS A retrospective review was conducted over a 6-year period on 347 consecutive patients with strabismus who presented after orbital wall fractures. The patients were evaluated for their demographic data, clinical presentation, and profiles, management, complications, and outcomes of strabismus. RESULTS Strabismus following orbital wall fractures was noted in 347 patients: 87.03% were men (n = 302) and 12.97% were women (n = 45). Fracture of the orbital floor in isolation or in combination with other walls was more frequently noted in 72.3% of patients (n = 251). The resultant strabismus included paralytic, restrictive, or both etiologies. Exotropia was noted most frequently in 25.65% of patients (n = 89), followed by exotropia with hypotropia in 20.75% of patients (n = 72). Ten percent of patients with strabismus (n = 34), who were observed for at least 6 months after injury, underwent surgical correction for strabismus. Preoperative diplopia was observed in 79.41% of patients (n = 27) and persisted after strabismus surgery in 15% of patients (n = 6). A successful outcome regarding the postoperative angle of deviation of 10 prism diopters or less horizontal and/or 5 prism diopters or less of vertical deviation with elimination of diplopia was observed in 41.17% of patients. CONCLUSIONS Strabismus following orbital wall fractures is complex and requires a tailored strategy. The current study found the orbital floor to be more frequently involved in orbital wall fractures. However, the resultant strabismus was a combination of paralytic and restrictive etiologies.

Wang F, Cao H, Zhang Y, Wang W. Analysis of Improvement Time and Influencing Factors of Diplopia after Intermittent Exotropia in Children. JOURNAL OF HEALTHCARE ENGINEERING 2022; 2022:2611225. [PMID: 35320998 PMCID: PMC8938045 DOI: 10.1155/2022/2611225] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Revised: 01/05/2022] [Accepted: 01/22/2022] [Indexed: 12/05/2022]
Abstract
Objective To observe and analyze the occurrence rate, improvement time, and influencing factors of diplopia after intermittent exotropia in children. Methods A total of 135 children with intermittent exotropia treated in our hospital from February 2019 to April 2021 were recruited. A reasonable surgical plan was exerted according to the preoperative examination of the children, the children were divided into groups according to their age, degree of strabismus, visual acuity, and binocular visual function, and the postoperative diplopia occurrence rate and improvement time of diplopia in different groups were observed and compared. Results Postoperative diplopia occurred in 74 of 135 children with intermittent exotropia, and the postoperative incidence of diplopia was 54.81%. All diplopia occurred on the first day after the operation. There were 62 cases of contradictory diplopia (83.78%) and 12 cases of fusion of powerless diplopia (16.22%). Except for 1 case of amalgamated powerless diplopia, diplopia was not significantly improved after 6 months, which seriously affected the life of the children after the second operation, and all the others were significantly improved within 90 days. The improvement time of diplopia was 3-90 days, and the average improvement time of diplopia was 13.25 ± 3.16 days. According to their age, the children were divided into the 3-6 years old group (n = 69), the 7-10 years old group (n = 47), and the 11-14 years old group (n = 19). Postoperative diplopia occurred in 25 cases (36.23%) in the 3-6 years old group, 34 cases (72.34%) in the 7-10 years old group, and 16 cases (84.21%) in the 11-14 years old group. There was a significant difference in the incidence of postoperative diplopia among the three groups (P < 0.05). There was a significant difference in the improvement time of diplopia among the three groups (P < 0.05). According to the degree of strabismus before the operation, the children were divided into the <50△ group (n = 74) and the ≥50△ group (n = 61). Postoperative diplopia occurred in 32 cases (43.24%) in the <50△ group and 43 cases (70.49%) in the ≥50△ group. There was a significant difference in the incidence of postoperative diplopia between the two groups (P < 0.05). There was a significant difference in the improvement time of diplopia among the three groups (P < 0.05). According to the results of the visual acuity examination, the patients were divided into the ≥0.8 (naked eye) group (n = 21), the ≥0.8 (ametropia) group (n = 32), and the <0.8 (amblyopia) group (n = 32). Among them, diplopia occurred in 10 cases (47.62%) in the ≥0.8 (naked eye) group, 40 cases (48.78%) in the ≥0.8 (ametropia) group, and 24 cases (75.00%) in the <0.8 (amblyopia) group. The incidence of diplopia in the <0.8 (amblyopia) group was significantly higher than that in the ≥0.8 (naked eye) group and the ≥0.8 (ametropia) group, and the difference was statistically significant (P < 0.05). The postoperative diplopia improvement time in the <0.8 (amblyopia) group was significantly higher than that in the ≥0.8 (naked eye) group and the ≥0.8 (ametropia) group, and the difference was statistically significant (P < 0.05). There was no significant difference in diplopia occurrence rate and diplopia improvement time between the ≥0.8 (naked eye) group and the ≥0.8 (ametropia) group (P > 0.05). According to the results of binocular visual function examination, 92 cases had a primary function, 45 cases (48.91%) had diplopia after the operation, the average recovery time of diplopia was 12.58 ± 3.16, 43 cases had no primary function, and 30 cases (69.77%) had diplopia after the operation. The average recovery time of diplopia was 13.02 ± 3.84. There was a significant difference in the incidence of diplopia between the two groups (χ 2 = 5.162). There was no significant difference in the recovery time of diplopia between the two groups (χ 2 = 0.570, P < 0.05). In 80 cases with secondary function, diplopia occurred in 36 cases (45.00%), and the average recovery time of diplopia was 10.14 ± 2.88; in 55 cases without secondary function, diplopia occurred in 39 cases (70.91%), and the average recovery time of diplopia was 14.86 ± 3.73. There was a significant difference in the incidence of diplopia between the two groups (χ 2 = 8.861, P < 0.002). There was a significant difference in the recovery time of diplopia between the two groups (χ 2 = 6.469, P < 0.001). In 77 cases with tertiary function, diplopia occurred in 32 cases (41.56%), and the average recovery time of diplopia was 9.61 ± 2.39; in 58 cases without tertiary function, diplopia occurred in 43 cases (74.14%), and the average recovery time of diplopia was 13.11 ± 3.05. There was a significant difference in the incidence of diplopia between the two groups (χ 2 = 14.221 P < 0.001). There was a significant difference in the recovery time of diplopia between the two groups (χ 2 = 5.355, P < 0.001). Conclusions The age, degree of strabismus, visual acuity, and binocular visual function of children with intermittent exotropia are significant factors affecting the occurrence rate and recovery time of diplopia after the operation. The younger the age, the smaller the degree of strabismus, the better the vision and the second or third grade of visual function, the smaller the occurrence rate of diplopia, and the shorter the recovery time of diplopia. Thus, the above influencing factors have a certain guiding significance in predicting the improvement of postoperative diplopia and the time of diplopia disappearance. The purpose of intermittent exotropia surgery in children is not only to correct eye position and improve appearance but also to establish normal retinal correspondence in order to obtain binocular monocular function. Furthermore, postoperative diplopia in children with concomitant exotropia is very common; therefore, careful examination, comprehensive analysis, and surgical plan should be designed according to the above factors. Stereoscopic vision training as early as possible after the operation is beneficial to the establishment of normal retinal correspondence and the elimination of diplopia.

Abstract
BACKGROUND Orbital metastasis from pancreatic tumors is extremely rare, and its clinical characteristics are still unclear. CASE PRESENTATION Our case was a 73-year-old female who noticed diplopia on right gaze 3 months before referral to us. Imaging studies demonstrated a mass involving the lateral rectus muscle in the right orbit. The results of pathological examination of an excised specimen corresponded to poorly differentiated adenocarcinoma. Systemic work-up revealed pancreatic carcinoma with peritoneal metastasis. The patient underwent chemotherapy. We reviewed literature on similar cases and found 19 reported cases of pancreatic tumors metastasizing to the orbit. The results of our review indicate a tendency for formation of solitary mass without bony erosion, delayed detection of the primary pancreatic carcinoma, and poorer prognosis of such tumors, compared to metastatic orbital tumors from other lesions. CONCLUSIONS We report a rare case of metastatic orbital tumor from an unknown primary pancreatic carcinoma. Clinical characteristics of cases with metastatic pancreatic tumors seem to be different from those with metastatic tumors from the other lesions. Pancreatic tumors are frequently asymptomatic in an early stage, leading to delayed detection of the primary pancreatic carcinoma and poorer prognosis.

Abstract
BACKGROUND Appropriate evaluation of diplopia requires separating serious from benign causes. If providers are not adept in this task, diagnosis of critical conditions may be delayed and unnecessary testing may result. METHODS We studied the records of 100 consecutive patients who presented to an emergency department between 2010 and 2020 with diplopia as a prominent symptom. We rated the performance of emergency medicine physicians (EMPs) and consulting neurologists (CNs) in the examination, diagnosis, and ordering of diagnostic tests according to standards based on neuro-ophthalmologic consultation and the neuro-ophthalmologic literature. RESULTS EMPs made no diagnosis or an incorrect diagnosis in 88 (88%) of 100 encounters. They ordered 14 unindicated and 12 incorrect studies, mostly noncontrast computed tomography scans. CNs made an incorrect diagnosis in 13 (31%) encounters. They ordered 6 unindicated and 2 incorrect studies. The total charge for unindicated and incorrect studies ordered by EMPs and CNs was $119,950. CONCLUSIONS EMPs and CNs made frequent errors in the examination, diagnosis, and ordering of diagnostic studies, leading to inefficient care and unnecessary testing. EMPs largely delegated the evaluation of diplopia to their consultants. If such consultative support were not available, the care of diplopic patients would be delayed. CNs performed more complete examinations, but rarely enough to allow appreciation of the pattern of ocular misalignment, contributing to misdiagnoses and ordering errors. The identification of these provider errors allows for more targeted teaching in the evaluation of diplopia.

Abstract
We report a case of sphenoid bone metastasis from breast cancer detected with diplopia, as first site of recurrence. Forty- year-old woman with left breast cancer underwent breast-conserving surgery and sentinel lymph node biopsy. The diagnosis was papillotubular carcinoma, pT1pN0, ER(+), PgR(+), HER2(-). Tweleb years later, the examination of diplopia revealed left abducens nerve palsy for sphenoid bone metastasis from breast cancer. Radiation therapy(a total dose of 36 Gy with VMAT)was administrated as topical treatment, but diplopia did not improve. After that, systemic treatment was performed, and 2 years and 6 months have passed since the recurrence was found, she is still alive. We need to be careful of orbital metastasis as a symptom of metastasis from breast cancer.

Abstract
OBJECTIVE Management of Graves' orbitopathy remains a challenge. Our previous case report has shown promising results for rabbit antithymocyte globulin (rATG) in the treatment of Graves' orbitopathy. DESIGN We present the response of 7 individuals with active moderate-to-severe steroid-resistant Graves' orbitopathy to rATG, representing preliminary results from a prospective single-center study. METHODS rATG was administered intravenously at a dose of 0.8-1.0 mg/kg daily (cumulative dose of 150-200 mg). The primary outcome measures at weeks 24 and 48 were ≥2-point reduction in Clinical Activity Score from baseline, a proptosis response, a diplopia response, and improvement of distant best-corrected visual acuity and mean retinal sensitivity. Key secondary outcomes included stabilization of ganglion cell complex thickness, a decrease of retinal nerve fiber layer in OCT, and a reduction in CD4/CD8 ratio and TRAb at 48 weeks. RESULTS An improvement in clinical activity score was observed in all patients, with disease inactivation in 3 cases. Proptosis reduction equal to or greater than 2 mm was noted for 8 of 10 eyes. Diplopia improved in three of 6 patients. There was an improvement in best-corrected visual acuity (from 0.69 to 0.78) and mean retinal sensitivity (from 20.8 to 23.5 dB). In addition, there was a long-lasting improvement in CD4/CD8 ratio in 6 patients. Two patients experienced adverse events (influenza and serum sickness). CONCLUSION rATG therapy offers a long-lasting improvement in moderate-to-severe steroid-resistant Graves' orbitopathy with improvement in functional vision (reduction of diplopia, improvement of visual acuity, retinal sensitivity, and VEP pattern). The therapy is well-tolerated. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov, identifier NCT05199103.
