Alterações oculares em escolares e adolescentes após início da pandemia por COVID-19 / Acute eye symptoms in schoolchildren and adolescents after the onset of COVID-19 pandemic

RESUMO Objetivo Identificar as alterações oculares em crianças e adolescentes secundárias ao fator do isolamento social e ao consequente aumento do uso de telas. Métodos Estudo observacional, descritivo e analítico, do tipo transversal realizado no período de julho a agosto de 2021, por meio da aplicação de questionários. Resultados Apresentaram cefaleia associada ao uso excessivo de tela 26,51% dos estudantes e 38,8% relataram suspeita de insuficiência de convergência. Em relação ao questionário de olho seco, 18,8% foram sintomáticos e 7,5% sintomáticos de difícil manejo. O computador foi o dispositivo mais utilizado em atividades escolares (71,5%), e, em segundo lugar, esteve o celular (66,3%). Casos sintomáticos de olho seco foram mais relatados em participantes que não faziam uso de computador (36,4%). Não foi possível identificar relação entre insuficiência de convergência e tempo de uso de dispositivos. Em relação ao olho seco, aqueles que passaram mais tempo em frente a tela relataram maior porcentagem de sintomas de difícil manejo (42,9%). Conclusão Foram mais prevalentes olho seco e sintomas de insuficiência de convergência na população estudada.

ABSTRACT Objective To identify eye conditions associated to social distancing and related increase in screen time exposure on children and teenagers. Methods Observational, descriptive and analytical study, with a cross-section design, carried out between July and August 2021, by questionnaire survey. Results Headaches related to excessive screen time exposure were reported by 26.51% of the students surveyed, while 38.8% reported suspect convergence insufficiency. Regarding the questionnaire about dry eye, 18.8% were symptomatic and 7.5% reported hard-to-manage symptoms. Computers were the devices most used for schoolwork (71.5%), followed by cellphones on second place (66.3%). Symptomatic cases of dry eye were mostly reported by participants that did not make use of computers (36.4%). It was not possible to establish a connection between convergence insufficiency and device usage time. Those participants that reported more screen time exposure also reported an increased percentage of hard-to-manage symptoms (42.9%), regarding dry eye. Conclusion Dry eye and convergence insufficiency symptoms were more prevalent in the surveyed population.

Isolated abducens nerve palsy associated with coronavirus disease: an 8-month follow-up / Paresia isolada do nervo abducente associada ao COVID-19: 8 meses de seguimento

ABSTRACT We report the case of a previously healthy 48-year-old man who developed an isolated abducens nerve palsy 18 days after presenting with coronavirus disease (COVID-19) confirmed by reverse transcriptase polymerase chain reaction. His main complaint at arrival was double vision. Ocular examination revealed a sixth cranial nerve palsy in the left eye. The incomitant esotropia at arrival was 30 prism diopters. Abduction was markedly limited, while adduction was normal in the left eye. The patient underwent complete clinical, neurological, and neuroimaging investigations, including cerebrospinal fluid sample analysis to rule out infectious causes. A conservative approach with orthoptic therapy and Fresnel prism was opted. Eight months after the onset of COVID-19, regression of the strabismus was observed, and the patient reported complete recovery of the diplopia. This case suggests that isolated abducens nerve palsy caused by severe acute respiratory syndrome coronavirus 2 infection may improve with a conservative approach.

RESUMO Reportamos o caso de homem previamente hígido, 48 anos, com paralisia isolada do nervo abducente 18 dias após infecção pelo novo coronavírus (COVID-19) confirmada por reação cadeia polimerase de transcriptase reversa. A principal queixa do paciente na admissão era diplopia. O exame ocular revelou paralisia do sexto nervo craniano do olho esquerdo. Esotropia incomitante no exame inicial media 30 dioptrias prismáticas. Abdução estava limitada com adução completa no olho esquerdo. O paciente foi submetido a investigação clínica e neurológica com exame de neuroimagem, incluindo análise de amostra do líquido cefalorraquidiano para descartar causas infecciosas. Optou-se por abordagem conservadora com terapia ortóptica e prisma de Fresnel. Oito meses após a infecção pelo COVID-19, o paciente evoluiu com regressão do estrabismo e informou recuperação completa do quadro. Este relato sugere que paralisia isolada do nervo abducente causada por SARS-CoV-2 pode melhorar com abordagem conservadora.

Clinical diagnosis and treatment of 9 childhood opsoclonus-myoclonus syndrome patients and application of standard rating scale / 中华神经科杂志

Objective:To summarize the clinical features of childhood opsoclonus-myoclonus syndrome (OMS), evaluate severity degree and prognosis using OMS Symptom Severity Standard Rating Scale.Methods:The clinical features,diagnosis, therapeutic regimen and follow-up of 9 children with OMS in Department of Neurology and Oncology Department of Children's Hospital of Fudan University between 2011 and 2019 were retrospectively reviewed. Severity degree and prognosis were evaluated using OMS Symptom Severity Standard Rating Scale.Results:Among the 9 children with OMS, 4 were males and 5 were females. The onset age ranged from 14 months to 5 years, with a median of 17 months. Main symptoms were opsoclonus, myoclonus, ataxia, motor function regression, behavior and mood changes and sleep disorders. Eghit patients were combined with tumor. Seven of them with neuroblastoma were confirmed by surgical pathology, the other one showed spontaneous regression and symptom remission without treatment. Eight patients received hormone combined with intravenous immunoglobulin, of which 3 cases received adrenocorticotropic hormone, while 5 cases received methylprednisolone pulse therapy, with prednisone sequential therapy, decreasing dose gradually. Rituximab was administrated in 3 patients whose annual recurrent time was≥2. Nine patients were divided into 3 groups according to OMS Symptom Severity Standard Rating Scale, 1 of mild degree, 3 of moderate degree, 5 of severe degree. There was no recurrence and sequelae in the mild-degree patient after 3 years follow-up. There was no recurrence and sequelae in 2 of the moderate-degree patients after 1-2 years follow-up. Different degrees of motor, cognitive sequelae were found in 1 of moderate-degree patients and all of severe-degree patients after 1-8 years follow-up.Conclusions:Childhood OMS patients have early onset age. Bad symptom severity before treatment and multiphase course are associated with poor prognosis. OMS Symptom Severity Standard Rating Scale is suitable for estimations of long-term prognosis.

Varied presentations of congenital ocular synkinesis: do they all fit congenital cranial dysinnervation disorder spectrum? / Apresentações variadas de sincinesias oculares congênitas: todas elas se enquadram ao espectro das desordens congênitas da desnervação craniana?

ABSTRACT Purpose: Synkinesis results from nerve miswirings and causes aberrant movements of the affected muscles. We present a series of cases of rare congenital ocular synkinesis involving the extraocular muscles and the levator palpebrae superioris and speculate the possibility of classifying these entities in the spectrum of congenital cranial dysinnervation disorder. Methods: Records of patients with the diagnosis of congenital ocular synkinesis were analyzed retrospectively. We analyzed the sex, laterality, and complete features of the ocular motility of each patient. Results: Nine patients with congenital ocular synkinesis were included. A slight predominance of women was noted. In terms of laterality, four patients had only the right eye involved, four had only the left eye, and one had both eyes involved. Notably, 55.5% were orthotropic in the primary position. The third, fourth, and sixth cranial nerves were involved in the miswiring in 100%, 44.4%, and 11.1% of the cases, respectively. Conclusions: Congenital synkinesis might present in a very eclectic and uncommon fashion. The aberrant innervation in these cases classifies them into the group of congenital cranial dysinnervation disorders.

RESUMO Objetivo: Sincinesias são resultado de inervações anômalas e ocasionam movimentos aberrantes dos músculos envolvidos. Apresentamos uma série com casos raros de sincinesias oculares congênitas dos músculos extraoculares e do levantador da pálpebra superior e especulamos a possibilidade de classificá-las dentro do espectro das desordens congênitas da desnervação cranianana. Métodos: Prontuários de pacientes com diagnóstico de sincinesia ocular congênita foram estudados retrospectivamente. Analisamos sexo, lateralidade e as características completas do exame de motilidade de cada paciente. Resultados: Nove pacientes com sincinesias oculares congênitas foram incluídos. Houve discreta predominância no sexo feminino. Em termos de lateralidade, o olho direito foi o único envolvido em 4 casos, o olho esquerdo também em 4 casos e 1 caso apresentou acometimento bilateral. 55,5% dos pacientes eram ortotrópicos na posição primária. Os III, VI e IV nervos participaram da sincinesia em 100%, 44,4% e 11,1% dos casos, respectivamente. Conclusões: Sincinesias oculares congênitas podem se apresentar de modo bastante eclético e incomum. A inervação aberrante presente em cada um desses casos os coloca na lista de candidatos a integrar o grupo das desordens congênitas da desenervação craniana.

Síndrome de flutter ocular e ataxia de tronco pós-infecciosa / The post-infectious ocular flutter syndrome and truncal ataxia

OBJETIVO: Descrever um quadro clínico subagudo pós-infeccioso caracterizado por ataxia de tronco e flutter ocular. RELATO DE CASO: Um homem de 37 anos previamente hígido, pouco após um quadro sistêmico inespecífico que se resolveu espontaneamente, deu início a movimentos involuntários hipercinéticos dos olhos, da cabeça e desequilíbrio importante. Os sintomas evoluíram em poucos dias. Ao exame, apresentava ataxia de tronco e presença de flutter ocular. O líquor mostrou pleocitose discreta. Ressonância magnética (RM) de crânio e exames laboratoriais normais. Houve melhora espontânea e total dos sintomas em cerca de três semanas. CONCLUSÃO: A síndrome de flutter ocular e ataxia de tronco é rara e é destacado a benignidade do quadro.

OBJECTIVE: To describe a post-infectious subacute clinical picture characterized by truncal ataxia and ocular flutter. CASE REPORT: A healthy 37-year-old man, a few days after spontaneously resolved nonspecific systemic disease, initiated involuntary hyperkinetic movements of the eyes, head, and major imbalance. The symptoms progressed within a few days. He presented ataxia of the trunk and presence of ocular flutter. CSF showed pleocytosis. Magnetic resonance of the skull and laboratory tests were normal. There was spontaneous and total improvement of symptoms in about three weeks. CONCLUSION: The ocular flutter syndrome and truncal ataxia is rare and the benignity of the condition is highlighted.

Esporotricose ocular: manifestações atípicas / Ocular sporotrichosis: atypical manifestations

Resumo A esporotricose humana e animal é uma infecção subaguda a crônica causada pelo fungo dimórfico Sporothrix schenckii. A esporotricose ocular tem ganhado destaque em função da epidemia de esporotricose urbana enfrentada pelo estado do Rio de Janeiro na última década e se apresenta classicamente como conjuntivite granulomatosa, mas formas atípicas podem ocorrer. Este artigo tem por objetivo relatar 2 casos atípicos de esporotricose ocular em pacientes imunocompetentes, ambos apresentando quadro clínico compatível com a síndrome oculoglandular de Parinaud associada à dacriocistite em um caso e presumivelmente à coroidite no outro caso.

Abstract Human and animal sporotrichosis is an infection caused by the dimorphic fungus Sporothrix schenckii, which is classified from subacute to chronic. Ocular sporotrichosis has been highlighted due to the epidemic of urban sporotrichosis faced by the state of Rio de Janeiro in the last decade and presents classically as granulomatous conjunctivitis, but atypical forms may occur. This article aims to report two atypical cases of ocular sporotrichosis in immunocompetent patients, both presenting a clinical picture compatible with Parinaud oculoglandular syndrome associated with dacryocystitis in one case and presumably to choroiditis in the other case.

Trochlear-oculomotor synkinesis: another congenital cranial dysinnervation disorder? / Sincinesia troclear-oculomotora: outro distúrbio congênito de denervação craniana?

ABSTRACT This report documents an unusual phenomenon. A 6-year-old girl with trochlear-oculomotor synkinesis presented with superior oblique and palpebral levator co-contraction. The literature was reviewed and the possibility of classifying this entity as a congenital cranial dysinnervation disorder was speculated.

RESUMO Este relato descreve um fenômeno incomum. Uma menina de 6 anos com sincinesia troclear-oculomotora apresentou co-contração do oblíquo superior e do levantador da pálpebra. A literatura foi revisada e especulou-se a possibilidade de classificar essa desordem como um distúrbio da congenital cranial dysinnervation disorder.

Research progress of oculomotor disorder in Parkinson's disease / 中华神经科杂志

Parkinson's disease (PD) is a common neurodegenerative disease characterized by bradykinesia,resting tremor,muscle rigidity,and abnormal gait posture.Ocular motor function test plays an important part in neurological examinations.It has been widely accepted that specific ocular motor patterns contribute to diagnosis of Parkinsonian syndrome including progressive supranuclear palsy and multiple system atrophy.However,recent studies have shown that patients of PD may also exhibit specific eye movement disorders,which will be helpful in the early diagnosis,evaluation and differential diagnosis of PD.In 2015,the Movement Disorder Society clinical diagnostic criteria for Parkinson's disease suggested that sustained staring evoked nystagmus could be used as an exclusive criterion for PD.The clinical features,detection methods and clinical significance of oculomotor dysfunction in PD are reviewed in this article.

Posterior internuclear ophthalmoplegia as a sign of pons infarction: a case report / 中华神经科杂志

Posterior internuclear ophthalmoplegia is a rare sign of pons infarction.Due to its mild clinical symptoms,it is easily misdiagnosed.In this article,we report a case of posterior internuclear ophthalmoplegia caused by pons infarction,discuss the causes of misdiagnosis and hope to attract the attention of doctors.By analyzing the clinical features of the case and reviewing the literatures,we try to differentiate the disease from multiple sclerosis,pons tumors and other diseases.The diagnosis was confirmed with thorough physical examination,laboratory test and imaging examination.Posterior internuclear ophthalmoplegia is a sign of pons infarction.

Presenting Internuclear Ophthalmoplegia with Peripheral Type Facial Palsy: Seven-and-a-Half Syndrome

A 49-year-old male presented with horizontal binocular diplopia without facial pain or skin lesion. Limitation of medial gaze in the left eye was revealed on neurological examination, which is accompanied by peripheral facial nerve palsy ipsilaterally. The diagnosis had been made based on the diffusion restriction lesion of left pontine tegmentum. We may denominate a “seven-and-a-half syndrome” and clinician should maintain a high level of awareness of the various syndromes associated with pontine lesions.

Long-term Results of Slanted Recession of Bilateral Lateral Rectus Muscle for Intermittent Exotropia with Convergence Insufficiency

PURPOSE: To evaluate the long-term efficacy of slanted lateral rectus recession in children for reducing distance and near exodeviation and near-distance deviation difference in intermittent exotropia with convergence insufficiency. METHODS: The medical records of 53 patients with convergence insufficiency intermittent exotropia who underwent slanted bilateral lateral rectus recession performed by a single surgeon and received follow-up for more than 12 months were retrospectively analyzed. Deviation angles at 1 day, 1 week, 1 month, 3 months, 6 months, and 12 months postoperatively and on the last visit were reviewed. Surgical success was defined as postoperative residual distance and near deviation angles ≤8 prism diopters and a difference between the near and distance angles ≤8 prism diopters. RESULTS: The mean duration of follow-up was 24 months (range, 12 to 61 months). On the last visit, the residual deviation angles were ≤8 prism diopters in 75.5% for distance, 62.3% for near, and 81.1% for the near-distance difference. Surgical success was achieved in 31 (58.5%) patients, and none of them manifested limitations in eye movements or diplopia at the last follow-up visit. CONCLUSIONS: Slanted lateral rectus recession is an effective surgical method for reducing distance and near exodeviation and near-distance deviation difference in intermittent exotropia with convergence insufficiency.

Conclusion: It was found that most respondents presented with visual discomfort and small percentages were affected by CI.

Metástasis intraorbitárias de cáncer de mama / Breast cancer orbital metastasis

Objetivo: Describir un caso raro de una paciente previamente diagnosticada con cáncer de mama que evolucionó después de algunos años con metástasis intraorbitaria. Métodos: Relato del caso y revisión de literatura. Resultados: La correlación del diagnóstico previo de neoplasia de mama y la presencia de múltiples lesiones en la órbita y regiones adjacentes ha permitido concluir que la paciente presentaba enfermedad metastásica. Las metástasis se presentan como manifestaciones cada vez más frecuentes en enfermos oncológicos. La órbita y estruturas próximas constituyen topografías poco usuales de diseminaciónde células neoplásicas y manifestaciones iniciales pueden mimetizar otras condiciones, retrasando el diagnóstico. Como se trataban de pequeñas lesiones, se ha optado por radioterapia como tratamiento único. Después del término la paciente evolucionó con regresión de sintomatología. Conclusiones: Aunque infrecuentes, manifestaciones oculares pueden ocurrir en enfermos oncológicos y la investigación de enfermedad metastático de la órbita es esencial para el seguimiento adecuado.

Objective: Description a rare case of a patient with previous diagnosis of breast cancer that evolved years after with orbital metastasis. Method: Case report and literature review. Results: The relation between the previous diagnosis of breast cancer and the presence of multiple orbital and adjacent lesions allowed concluding that the patient presented metastatic disease. Metastasis presented as a common manifestation in oncological patients. Orbit and neighboring structures constitute unusualsite of neoplastic cells dissemination and initial manifestations could mimic other conditions, which can slow diagnosis. As they were small lesions that are close to noble structures, it was opted by performing exclusive radiotherapy. After the end of treatment, the patient referred improvement of her symptoms. Conclusions: Although unusual, ocular manifestations could occur in oncological patients and orbit metastatic disease investigation is essential to the proper follow.

Introduction: The Convergence Insufficiency Symptom Survey Questionnaire (CISS-V15) is a tool for diagnosis and monitoring of treatment of patients with convergence insufficiency. Objective: To determine the validity of the questionnaire CISS-V15 for the diagnosis of convergence insufficiency against clinical tests assessing the oculomotor state in optometric patients seen in con-sultation in the cities of Recife and Salvador, Brazil. Methods: A descriptive transversal study with a quantitative approach was conducted with 50 patients from two educational institutions in Brazil. Patients were selected from those that met the inclusion criteria for applying the questionnaire. Patients with convergence insufficiency and those with normal binocular vision were identified. The results of the questionnaire and ocular motility tests were analyzed to estimate central tendency measures and to analyze the sensitivity and specificity of the questionnaire. Results: The test had a sensitivity of 0.83 and a specificity of 0.81. Conclusions: Given the clinical test, the CISS-V15 questionnaire proved to be valid to classify individuals with convergence insufficiency, and those with normal binocular vision, which makes it a valuable tool for the diagnosis and monitoring of the treatment of patients with convergence insufficiency.

Síndrome opsoclonus-mioclonus idiopático en paciente adulto: reporte de caso / Idiopathic opsoclonus-myoclonus syndrome in an adult patient: a case report

Presentamos el caso de un paciente de 31 años con el síndrome de opsoclonus-mioclonus, entidad poco frecuente caracterizada por movimientos oculares multidireccionales (opsoclonus) y mioclonías, el cual puede estar asociado a ataxia, temblor y alteración del estado de conciencia. Es una entidad descrita como manifestación infecciosa secundaria, paraneoplásica o idiopática, siendo las etiologías más frecuentes en la población adulta. Existe evidencia de un mecanismo inmunológico en su patogénesis por lo que el tratamiento con esteroides y/o drogas inmunomoduladoras es ampliamente empleado aunque no existen estudios que soporten su uso prolongado en la evolución favorable del cuadro. Nuestro paciente recibió tratamiento esteroideo precoz y se observó mejoría y recuperación temprana. Es importante el reconocimiento de este cuadro por la posibilidad de estar relacionado a neoplasias subyacentes.

We report a case of 31 a year old male patient with opsoclonus-myoclonus syndrome, a rare entity which is characterized by multidirectional eye movements (opsoclonus) and myoclonus. It can be associated with ataxia, tremor and altered level of consciousness. This entity is reported as secondary manifestation of infectious, paraneoplastic or idiopathic disease, the more common etiologies in adult population. There is evidence of an immunological mechanism involved in its pathogenesis. The treatment with steroids and/or immunomodulator drugs is widely used although there are no trials supporting its long term use in clinical improvement. Our patient received early steroid treatment with a prompt improvement and recovery. It is important to recognize this entity for the possibility of being related with underlying malignancies.

Parinaud's oculoglandular syndrome and possibly causing cortical cataract / Síndrome oculoglandular de Parinaud como possível causa de catarata cortical

According to the World Health Organization, cataract is the leading cause of blindness and visual impairment throughout the world. However, the etiology of cataracts often remains unknown. This report describes the development of cortical cataract in a patient after Parinaud's oculoglandular syndrome caused by the fungus Sporothrix schenckii.

De acordo com a Organização Mundial de Saúde, a catarata é a principal causa de cegueira e deficiência visual em todo o mundo. No entanto, a etiologia das cataratas frequentemente permanece desconhecida. Este relato descreve o desenvolvimento de catarata cortical em um paciente após Síndrome oculoglandular de Parinaud causada pelo fungo Sporothrix schenckii.

Influence of head posture on the visual acuity of children with nystagmus / Influência da postura da cabeça na acuidade visual de crianças com nistagmo

Purpose: Evaluate the relationship between the postural alignment of the head and possible interference in the view of children. Methods: We evaluated 11 children between 2 and 7 years of age of both sexes, with the visually impaired, who had nystagmus and head lock position. The test Lea Grating Acuity Test® was used to collect measurements of visual acuity. This applied on two occasions: with and without postural alignment of the head. For reliability of the postural alignment of the head, the slopes were measured by Fisiologic® software. Results: The children had a poorer performance after physiological postural alignment. This poor performance is possible due to loss of position lock nystagmus to gain postural alignment, said to be ideal. Postural compensations were observed, and sharply increased eyestrain. Conclusion: The pursuit of traditional postural alignment affect the visual response of children with visual impairments. .

Objetivo: Avaliar a relação entre o alinhamento postural da cabeça e a possível interferência na visão de crianças. Métodos: Foram avaliadas 11 crianças, entre 2 e 7 anos de idade de ambos os sexos, com o diagnóstico de deficiência visual, que apresentavam nistagmo e posição de bloqueio de cabeça. O teste Lea Grating Acuity Test® foi utilizado para coletar medidas de acuidade visual. Este aplicado em dois momentos: sem e com o alinhamento postural da cabeça. Para confiabilidade do alinhamento postural da cabeça, as inclinações foram medidas pelo software Fisiologic®. Resultados: As crianças apresentaram pior desempenho após o alinhamento postural fisiológico. Este pior desempenho é possível devido à perda da posição de bloqueio do nistagmo para ganho do alinhamento postural, dito como ideal. Foram observadas compensações posturais e maior esforço visual. Conclusão: A busca do alinhamento postural tradicional prejudica a resposta visual de criança com deficiência visual. .

Síndrome de opsoclonia-mioclonia-ataxia em paciente com AIDS / Opsoclonus-myoclonus-ataxia syndrome in an AIDS patient

É relatado aqui o caso de uma mulher de 38 anos com AIDS que desenvolveu a síndrome de opsoclonia-mioclonia-ataxia em um período diferente dos outros casos já relatados na literatura. A síndrome de opsoclonia-mioclonia-ataxia já tinha sido relatada como manifestação inicial de AIDS, assim como no momento da soroconversão de HIV e na síndrome de reconstituição imune. Este caso é único, uma vez que a paciente tinha contagem elevada de CD4 e carga viral negativa no momento em que a síndrome de opsoclonia-mioclonia-ataxia ocorreu.

We report the case of a 38-year-old woman with AIDS who developed opsoclonus-myoclonus-ataxia syndrome during a period different from other cases reported in literature. Opsoclonus-myoclonus-ataxia syndrome had already been reported as the initial neurological presentation of AIDS, as well as at the time of HIV-seroconversion and immune reconstitution syndrome. Our case is unique since the patient had an elevated CD4 count and negative viral load in the period when the opsoclonus-myoclonus-ataxia syndrome occurred.
