RESUMEN
Diplopia, or double vision, has been listed as a rare adverse effect of intravenous hydromorphone, although there are no case studies or literature documenting this. We detail a case of acute transient diplopia correlated with the use of intraoperative hydromorphone and postoperative hydromorphone patient-controlled analgesia. Although the mechanism for this adverse effect is unknown, there may be risk factors that predispose patients to the potential toxic metabolic effects of hydromorphone. We share the first published case of diplopia as a clinically relevant adverse effect of hydromorphone and propose a potential reason behind this association.

PURPOSE: To investigate the prevalence and risk of new-onset abducens nerve palsy and acute-onset diplopia following mRNA COVID-19 vaccination. METHODS: In this retrospective, population-based study, patient data from the COVID-19 Research Network of TriNetX was searched via the TriNetX Analytics platform for patients who received specific vaccinations based on Common Procedural Technology codes. We recorded instances of newly diagnosed abducens nerve palsy and diplopia within 21 days following each vaccination event. RESULTS: Of the 3,545,224 patients (mean age at vaccination, 46.2 ± 21.3 years) who received the mRNA COVID-19 vaccine, 12 (<0.0001%) patients had a new diagnosis of abducens nerve palsy and 453 (0.013%) had acute-onset diplopia within 21 days of first dose of COVID-19 vaccination. After propensity score matching, the relative risk for new abducens nerve palsy diagnosis after the first dose of COVID-19 vaccination was not significantly different from that after influenza (RR, 0.77), Tdap (RR, 1.0), or the second dose of the COVID-19 vaccinations (RR, 1.00). Furthermore, there was a lower risk of abducens nerve palsy diagnosis after the first dose of the COVID-19 vaccination compared with the risk after COVID-19 infection (RR, 0.15). CONCLUSIONS: The risk of a new abducens nerve palsy diagnosis following the first dose of the COVID-19 vaccine is lower than the risk associated with COVID-19 infection itself. There is no evidence to suggest a causal relationship between COVID-19 vaccination and the development of abducens nerve palsy.

Facial filler injections are the second most commonly performed in-office cosmetic procedure. Vision loss is the most feared complication of hyaluronic acid (HA) filler injection, but isolated ophthalmoplegia can also occur. We report the case of a 45-year-old woman who developed nausea and diplopia following HA filler injection to the bilateral periorbital region. She presented with a left hypertropia and left-sided motility deficit without vision involvement. MRI of the orbits demonstrated mild enhancement and enlargement of the left inferior rectus and inferior oblique muscles. Treatment consisted of hyaluronidase injection and oral steroids. HA filler can cause isolated ocular misalignment and diplopia without associated vision loss. Patients should be counseled on these risks before undergoing soft tissue augmentation of the face with HA filler.

PURPOSE: To assess the duration, incidence, reversibility, and severity of adverse events (AEs) in patients with thyroid eye disease (TED) treated with teprotumumab. DESIGN: Multicenter, retrospective, observational cohort study. PARTICIPANTS: Patients with TED of all stages and activity levels treated with at least 4 infusions of teprotumumab. METHODS: Patients were treated with teprotumumab between February 2020 and October 2022 at 6 tertiary centers. Adverse event metrics were recorded at each visit. MAIN OUTCOME MEASURES: The primary outcomes measure was AE incidence and onset. Secondary outcome measures included AE severity, AE reversibility, AE duration, proptosis response, clinical activity score (CAS) reduction, and Gorman diplopia score improvement. RESULTS: The study evaluated 131 patients. Proptosis improved by 2 mm or more in 77% of patients (101/131), with average proptosis improvement of 3.0 ± 2.1 mm and average CAS reduction of 3.2 points. Gorman diplopia score improved by at least 1 point for 50% of patients (36/72) with baseline diplopia. Adverse events occurred in 81.7% of patients (107/131). Patients experienced a median of 4 AEs. Most AEs were mild (74.0% [97/131]), 28.2% (37/131) were moderate, and 8.4% (11/131) were severe. Mean interval AE onset was 7.9 weeks after the first infusion. Mean resolved AE duration was 17.6 weeks. Forty-six percent of patients (60/131) demonstrated at least 1 persistent AE at last follow-up. Mean follow-up was 70.2 ± 38.5 weeks after the first infusion. The most common type of AEs was musculoskeletal (58.0% [76/131]), followed by gastrointestinal (38.2% [50/131]), skin (38.2% [50/131]), ear and labyrinth (30.5% [40/131]), nervous system (20.6% [27/131]), metabolic (15.3% [20/131]), and reproductive system (12.2% [16/131]). Sixteen patients (12.2%) discontinued therapy because of AEs, including hearing loss (n = 4), inflammatory bowel disease flare (n = 2), hyperglycemia (n = 1), muscle spasms (n = 1), and multiple AEs (n = 8). CONCLUSIONS: Adverse events are commonly reported while receiving teprotumumab treatment. Most are mild and reversible; however, serious AEs can occur and may warrant treatment cessation. Treating physicians should inform patients about AE risk, properly screen patients before treatment, monitor patients closely throughout therapy, and understand how to manage AEs should they develop.

BACKGROUND: This is an updated version of a Cochrane Review last updated in 2020. Epilepsy is a common neurological disorder, affecting 0.5% to 1% of the population. In nearly 30% of cases, epilepsy is resistant to currently available drugs. Pharmacological treatment remains the first choice to control epilepsy. Lamotrigine is a second-generation antiseizure medication. When used as an add-on (in combination with other antiseizure medications), lamotrigine can reduce seizures, but with some adverse effects. OBJECTIVES: To evaluate the benefits and harms of add-on lamotrigine, compared with add-on placebo or no add-on treatment in people with drug-resistant focal epilepsy. SEARCH METHODS: For this update, we searched the Cochrane Register of Studies (CRS Web) and MEDLINE (Ovid) on 3 October 2022 with no language restrictions. CRS Web includes randomised and quasi-randomised controlled trials from PubMed, Embase, ClinicalTrials.gov, the World Health Organization International Clinical Trials Registry Platform (ICTRP), Cochrane Central Register of Controlled Trials (CENTRAL), and the Specialised Registers of Cochrane Review Groups, including Epilepsy. SELECTION CRITERIA: We included randomised controlled trials (RCTs) that investigated add-on lamotrigine versus add-on placebo or no add-on treatment in people of any age with drug-resistant focal epilepsy. We used data from the first period of eligible cross-over trials. DATA COLLECTION AND ANALYSIS: For this update, two review authors independently selected trials and extracted data. Our primary outcome was 50% or greater reduction in seizure frequency. Our secondary outcomes were treatment withdrawal, adverse effects, cognitive effects, and quality of life. Primary analyses were by intention-to-treat. We performed sensitivity best- and worse-case analyses to account for missing outcome data. We calculated pooled risk ratios (RRs) with 95% confidence intervals (95% Cls) for dichotomous outcomes. MAIN RESULTS: We identified no new studies for this update, so the results and conclusions of the review are unchanged. We included five parallel-group studies in adults or children, eight cross-over studies in adults or children, and one parallel study with a responder-enriched design in infants. In total, these 14 studies enroled 1806 eligible participants (38 infants, 199 children, 1569 adults). Baseline phases ranged from four to 12 weeks and treatment phases ranged from eight to 36 weeks. We rated 11 studies (1243 participants) at low overall risk of bias and three (697 participants) at unclear overall risk of bias due to lack of information on study design. Four studies (563 participants) reported effective blinding. Lamotrigine compared with placebo probably increases the likelihood of achieving 50% or greater reduction in seizure frequency (RR 1.80, 95% CI 1.45 to 2.23; 12 trials, 1322 participants (adults and children); moderate-certainty evidence). There is probably little or no difference in risk of treatment withdrawal for any reason among people treated with lamotrigine versus people treated with placebo (RR 1.11, 95% CI 0.91 to 1.37; 14 trials; 1806 participants; moderate-certainty evidence). Lamotrigine compared with placebo is probably associated with a greater risk of ataxia (RR 3.34, 99% Cl 2.01 to 5.55; 12 trials; 1525 participants; moderate-certainty evidence), dizziness (RR 1.76, 99% Cl 1.28 to 2.43; 13 trials; 1768 participants; moderate-certainty evidence), nausea (RR 1.81, 99% CI 1.22 to 2.68; 12 studies, 1486 participants; moderate-certainty evidence), and diplopia (RR 3.79, 99% Cl 2.15 to 6.68; 3 trials, 944 participants; moderate-certainty evidence). There is probably little or no difference in the risk of fatigue between lamotrigine and placebo (RR 0.82, 99% CI 0.55 to 1.22; 12 studies, 1552 participants; moderate-certainty evidence). AUTHORS' CONCLUSIONS: Lamotrigine as an add-on treatment for drug-resistant focal seizures is probably effective for reducing seizure frequency. Certain adverse effects (ataxia, dizziness, diplopia, and nausea) are probably more likely to occur with lamotrigine compared with placebo. There is probably little or no difference in the number of people who withdraw from treatment with lamotrigine versus placebo. The trials were of relatively short duration and provided no long-term evidence. In addition, some trials had few participants. Further trials are needed to assess the long-term effects of lamotrigine and to compare lamotrigine with other add-on drugs.

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: To quantify changes in extraocular muscle (EOM) cross-sectional areas (CSA) on orbital imaging in patients with thyroid eye disease before and after teprotumumab treatment, and assess for correlation with clinical outcomes. METHODS: This retrospective study included thyroid eye disease patients treated with teprotumumab who had pre- and post-treatment CT imaging. Reformatted oblique coronal images were created for each orbit in a plane perpendicular to the optic nerve. EOM CSA measurements were performed by 2 radiographic reviewers and averaged. Primary outcomes included change in ratio of total EOM to orbit CSA, and of each individual muscle group to orbit CSA, before and after treatment. Secondary outcomes included subanalysis based on age (≥40, <40 years) and Clinical Activity Score (CAS) (≥4, <4), and comparison with clinical outcomes including CAS, Hertel exophthalmometry, Gorman diplopia score, and extraocular motility. RESULTS: Forty-eight orbits of 24 patients (16 female, mean age 57.9 years) were included. There was a significant reduction in the total EOM to orbit CSA ratio ( p < 0.01) and for each individual rectus muscle to orbit CSA ratio ( p < 0.01 for all groups). Total EOM to orbit CSA ratios were reduced for 21 patients (87.5%); this was statistically significant in 13 patients (54.2%). There was significant improvement in CAS, proptosis, diplopia, and EOM motility ( p < 0.01 for all categories). There was a significant correlation between reduction of EOM CSA, and reduction of diplopia ( p < 0.01) and EOM motility ( p < 0.01). CONCLUSIONS: EOM CSA is significantly reduced following treatment with teprotumumab, and correlates with clinical findings including improvement in extraocular motility and diplopia.

BACKGROUND: There have been several studies on inflammatory ophthalmic diseases; however, few studies have reported neuro-ophthalmological symptoms, such as diplopia and ocular motor nerve palsy, after coronavirus disease 2019 (COVID-19) vaccination. Therefore, this study aimed to report neuro-ophthalmological symptoms in patients after COVID-19 vaccination. METHODS: This was a retrospective study based on the medical records of 10 patients who visited our ophthalmology clinic in 2021 with symptoms, such as diplopia (nine patients) and decreased visual acuity (one patient), and showed findings, such as ocular motor nerve palsy, after vaccination against COVID-19. RESULTS: One patient had third nerve palsy, two had sixth nerve palsy, and five had fourth nerve palsy. One patient complained of subjective binocular diplopia but all test results were normal. One patient presented with decreased visual acuity accompanied by a sudden increase in intraocular pressure and orbital cellulitis in the other eye. The symptoms improved gradually in most patients. Compared with previous studies, this study reported three cases of antiplatelet therapy that was initiated due to the older age of the patients and underlying diseases. CONCLUSION: As COVID-19 vaccines can cause neuro-ophthalmological diseases, such as ocular motor nerve palsy, patients' age and underlying diseases should be considered while administering them.

Diplopia, or double vision, is a symptom resulting from the perception of two images of a single object. We report a case of a possible silodosin-induced diplopia never reported before in the literature. We suggest that binocular diplopia should be considered in people assuming silodosin even if further studies should be conducted to explore possible pathogenetic mechanisms.

RATIONALE: Miller Fisher syndrome (MFS) is a rare variant of Guillain-Barre syndrome, classically diagnosed based on the clinical triad of ataxia, areflexia, and ophthalmoplegia. MFS is usually preceded by viral infections and febrile illness; however, only a few cases have been reported after vaccinations. PATIENT CONCERNS: A 53-year-old hypertensive male presented with a 2-day history of progressive ascending paralysis of the lower limbs along with diplopia and ataxia, 8 days after the first dose of the Sinovac-Coronavac coronavirus disease 2019 (COVID-19) vaccination, with no prior history of any predisposing infections or triggers. DIAGNOSES: Physical examination showed moderate motor and sensory loss with areflexia in the lower limbs bilaterally. Routine blood investigations and radiological investigations were unremarkable. Cerebrospinal fluid analysis showed albuminocytologic dissociation and nerve conduction studies revealed prolonged latencies with reduced conduction velocities. The diagnosis of MFS was established based on the findings of physical examination, cerebrospinal fluid analysis, and nerve conduction studies. INTERVENTIONS: A management plan was devised based on intravenous immunoglobulins, pregabalin, and physiotherapy. However, due to certain socioeconomic factors, the patient was managed conservatively with regular physiotherapy sessions. OUTCOMES: Follow-up after 6 weeks showed remarkable improvement, with complete resolution of symptoms 10 weeks after the discharge. LESSONS: This case suggests that MFS is a rare adverse effect after COVID-19 vaccination and additional research is required to substantiate a temporal association. Further studies are needed to understand the pathophysiology behind such complications to enhance the safety of COVID-19 vaccinations in the future.

Carbamazepine remains a first-line antiepileptic medication for the treatment of partial seizures. Despite its widespread use, carbamazepine has significant neurotoxicity and hypersensitivity reactions. We report a case of a patient post-kidney transplant who was on regular carbamazepine for childhood epilepsy and developed nystagmus, diplopia and a broad-base gait after receiving diltiazem. Understanding of the interaction between diltiazem and carbamazepine is necessary to prevent the neurotoxic effects.

Trastuzumab emtansine (T-DM1) is a human epidermal growth factor receptor 2 (Her2) - targeted antibody-drug conjugate that is approved for patients previously treated with trastuzumab and a taxane for Her2-positive advanced breast cancer and those who have progressed within 6 months of completion of adjuvant chemotherapy, as well as for patients with residual invasive Her2-positive disease after the completion of adjuvant chemotherapy. Peripheral neuropathy is a common adverse event; however, ocular events have also been described. With the current report we present the case of a 67-year old woman who developed transient grade 2-3 blurred vision after the first T-DM1 infusion, which was complicated with grade 2 diplopia causing vertigo after the second infusion. After extended investigation, this symptomatology was attributed to central neurotoxicity, and gradually resolved after T-DM1 discontinuation.

This study aimed to develop a pharmacokinetic (PK) model of oxcarbazepine (OXC) and analyse the relationship between monohydroxylated derivative (MHD), an active metabolite of OXC, and the adverse events of OXC. We obtained 711 OXC samples from 618 patients with epilepsy who were enrolled in the Epilepsy Registry Cohort of Seoul National University Hospital from February 2011 to January 2014. The plasma PK model was developed using a nonlinear mixed-effect modelling method with NONMEM (ver 7.3). A one-compartment model with a first-order absorption model and proportional residual error adequately described the MHD concentration-time profiles. The only covariate incorporated for CL/F and V/F was body weight. Of the 447 patients analysed, 28 (6.26%) had dose-related adverse events (DRAEs), which were dizziness, somnolence, headache, and diplopia. For DRAE occurrence, the cut-off values of the MHD trough and AUC were 12.27 mg/L (specificity 0.570, sensitivity 0.643) and 698.5 mg h/L (specificity, sensitivity 0.571), respectively. Multivariate analysis showed the sole dizziness symptom was significantly associated with both the MHD trough and the AUC (p = 0.013, p = 0.038, respectively). We newly developed a population PK model using sparse sampling data from patients with epilepsy, and the model better reflects the actual clinical situation.

Resumo Paciente do sexo feminino, 19 anos, com queixa de diplopia, náusea e vômito de início súbito. Ao exame físico, a paciente apresentava rotação da cabeça para a esquerda e limitação da adução do olho direito, sugerindo paresia do músculo reto medial. Ausência de ptose palpebral ou paresia de outra musculatura ocular extrínseca e sem outras alterações na avaliação oftalmológica. Foi relatado pelo paciente o uso de Metronidazol, duas doses de 500 mg, no mesmo dia em que os sintomas começaram. A ressonância magnética do crânio foi solicitada. O resultado mostrou um cisto da glândula pineal, estando os outros aspectos dentro da normalidade. A paresia do músculo reto medial e diplopia persistiram por 14 dias, mesmo após a suspensão do antibiótico, optando, assim, por iniciar a corticoterapia oral, evoluindo com boa resposta clínica, melhora dos sintomas e regressão da paresia muscular.
Abstract Female patient, 19 years old, with a complaint of diplopia, nausea and vomiting of sudden onset. Upon physical examination, the patient presented herself with the head position rotated to the left and limitation of adduction of the right eye, suggesting paresis of the medial rectus muscle. Absence of palpebral ptosis or paresis of other extrinsic musculature of the eye, and without other alterations in the ophthalmological evaluation. It was reported by the patient the use of Metronidazole, two doses of 500 mg, the same day the symptoms started. The magnetic resonance imaging of the skull was requested. The result showed a cyst of the pineal gland, the other aspects being within normality. The paresis of the medial rectus muscle and diplopia persisted for 14 days, even after the antibiotic was discontinued, thus opting to initiate oral corticosteroid therapy, evolving with good clinical response, improvement of symptoms and regression of muscular paresis.
