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.

Study of Geometric Illusory Visual Perception - A New Perspective in the Functional Evaluation of Children With Strabismus.

Despite the various perceptual-motor deficits documented in strabismus, there is a paucity of studies evaluating visual illusions in patients with strabismus. The aim of this study was to examine how the illusionary perception occurs in children/adolescents (10-15 years old) with strabismus with referral for surgery to correct ocular deviations. A controlled cross-sectional study was carried out in which 45 participants with strabismus and 62 healthy volunteers aged 10-15 years were evaluated. The behavioral response to three geometric illusions [Vertical-Horizontal illusion, Müller-Lyer illusion (Bretano version) and Ponzo illusion] and respective neutral stimuli (non-illusory images) regarding the estimation of image size and response time were measured using the Method of Adjustment. To analyze the influence of secondary factors: type of ocular deviation (convergent, divergent or associated with vertical deviation); amount of eye deviation; presence of amblyopia and stereopsis, a one-way ANOVA was performed. Among the tested illusions, children with strabismus showed greater susceptibility (p = 0.006) and response time (p = 0.004) to Ponzo's illusory images. Children with strabismus and preserved stereopsis, on the other hand, showed similar susceptibility and response time to control group patients to the Ponzo illusion (p < 0.005). Patients with amblyopia showed overcorrection in the estimate of non-illusory Ponzo images (p = 0.046). Children with horizontal ocular deviation (esotropia or exotropia) associated with vertical deviation (hypertropia, DVD and/or alphabetical anisotropy) showed higher susceptibility to vertical adjustment images for the Müller-Lyer illusion (Brentano version) (p = 0.017). Individuals with strabismus tended to overcorrect the length of the straight-line segment adjusted for non-illusory images when testing non-illusory images in the Müller-Lyer test (Brentano version) (p = 0.009), as well as for the neutral images in the Vertical-Horizontal test (p = 0.000). The findings indicated impairment in the perception of geometric illusions and neutral figures, especially for the Ponzo illusion test by children with strabismus. As the behavioral response to illusory images may indirectly reflect the visual and morphofunctional alterations present in these individuals, we suggest that the investigation of visual illusory perception can be used as a new research strategy in the field of investigating the visual function in strabismus.

Epidemiology and prognosis factors in open globe injuries in the Federal District of Brazil.

OBJECTIVE: To identify the epidemiological profile and prognostic factors of open globe injuries that require emergency surgical treatment. DESIGN: Retrospective cohort study. SUBJECTS: Patients with OGI who underwent publicly funded emergency surgical treatment in the Federal District from 2014 to 2018. METHODS: Data were collected by reviewing electronic medical records through a questionnaire and tabulated. The statistical analysis was performed in SPSS Statistics 26.0.0.0 (p ≤ 0.05). RESULTS: A total of 359 records were included, corresponding to 336 eyes of 334 patients (294 males and 40 females). The average age was 32.7 years. The affected eye was the right eye in 165 cases, the left eye in 166 cases, and both eyes in 3 cases. The average time between injury and hospitalization was 75.7 h, and the time between injury and surgery averaged 173.7 h. The injury types were as follows: 197 penetrating; 109 rupture; 19 IOFB; 11 perforating. The injuries were in the following zones: 181 zone I; 82 zone II; 70 zone III. The OTS grades were as follows: 57 were classified as grade 1; 101 were grade 2; 142 were grade 3; 28 were grade 4; and 8 were 5. The most commonly performed surgeries were corneal suture, corneoscleral suture, and evisceration. The most common clinical features were traumatic cataract, herniated iris and hyphema. The following were risk factors for poor prognosis: zone III, time between trauma and surgery > 72 h, rupture injury, retinal detachment, disorganization of the eyeball, endophthalmitis, uveal prolapse, OTS classification 1 or 2, and low initial visual acuity. The following factors predicted a good prognosis: initial VA > 1/200, penetrating injury, OTS 4 and zone II. CONCLUSIONS: The high frequency of many of these factors may explain the high rate of severe visual loss found. Injury localization in zone II was identified as a previously unrecognized protective factor against severe visual loss.

Epidemiology of strabismus surgery in a public hospital of the Brazilian Federal District / Epidemiologia da cirurgia de estrabismo em um hospital público de Brasília, Distrito Federal

Abstract Purpose: to determine the prevalence of different types of strabismus submitted to a surgical procedure in a public hospital in the Brazilian Federal District. Methods: Retrospective cross-sectional review of medical records of patients who underwent strabismus surgery performed by the same surgeon from 2004 to 2014. Incomplete records were excluded from the study. Variables included sex, age, type of strabismus, type of surgery, and re-surgeries. Strabismus was classified into three main types (esotropia, exotropia, and pure vertical deviation), and their subtypes. The type of surgery was determined by the number of muscles operated on (up to two, or more than two), the involvement of oblique and vertical rectus muscles, and muscle displacement. Results: 563 patients were reviewed and 531 were included in the study. The average age was 12.7 years, and females accounted for 54.4% of total patients. Esotropia was the most frequent type of strabismus (74%), followed by exotropia (23.7%) and pure vertical deviation (2.3%). The most frequent subtype of esotropia was infantile (49.1%), with 16.1% of these surgeries performed before the age of 2. Constant exotropia was the most frequent subtype of exotropia (27.8%). The prevalence of esotropia decreased with age, whereas that of exotropia increased. 52.3% of surgeries involved more than two muscles. An association between different types of deviation was found in 58.9% of patients. In cases of paralytic strabismus, the sixth nerve was the most affected (46%). Re-surgeries accounted for 10.7% of total surgeries. Conclusion s: Esotropias were the most common types of strabismus, especially infantile esotropia. Most cases were associated with other types of deviation, and needed more complex surgeries, involving more than two muscles. This study expects to contribute to the planning of health measures that may effectively improve the assistance provided to the population.

Resumo Objetivo: Determinar a prevalência dos diferentes tipos de estrabismo submetidos a intervenção cirúrgica em um hospital público de Brasília, Brasil. Métodos: Estudo retrospectivo de corte transversal de prontuários médicos dos pacientes submetidos a cirurgias de estrabismo por um mesmo cirurgião, de 2004 e 2014. Foram excluídos prontuários incompletos. Variáveis pesquisadas incluíram sexo, idade, classificação do estrabismo, tipo da cirurgia e reoperações. Os estrabismos foram classificados em três tipos principais (esotropia, exotropia e desvio vertical puro) e seus subtipos. Avaliação do tipo da cirurgia considerou o número de músculos operados (intervenção em até 2 ou em mais músculos), o envolvimento de músculos oblíquos, retos verticais e transposição muscular. Resultados: Foram avaliadas 563 pacientes e 531 foram incluídas na análise. A média de idade foi 12,7 anos e o sexo feminino respondeu por 54,4%. A esotropia foi o tipo de estrabismo mais frequente (74%), seguido pela exotropia (23,7%) e desvio vertical puro (2,3%). O subtipo de esotropia mais frequente foi o infantil (49,1%), com 16,1% destas cirurgias realizadas antes dos 2 anos de vida. A exotropia constante foi o subtipo mais observado (27,8%) de exotropia. A proporção de esotropia diminuiu com a idade, enquanto a de exotropia aumentou. 52,3% das cirurgias envolveram mais de dois músculos. Associação de diferentes tipos de desvio foi observada em 58,9% dos pacientes. Dentre os estrabismos paralíticos, o VI nervo foi o mais acometido (46%). Reoperações corresponderam a 10,7% do total. Conclusão: As esotropias foram os estrabismos cirúrgicos mais comuns, especialmente a esotropia infantil. A maioria dos casos estava associada a outras formas de desvio e necessitaram de cirurgias mais complexas, envolvendo mais de 2 músculos. Espera-se que dados do estudo possam contribuir no planejamento de ações de saúde efetivas para melhorar a assistência à população.

Alterações da campimetria, tomografia de coerência óptica e função visual em pacientes portadores de esclerose múltipla / Campimetry changes, optical coherence tomography and visual function changes in patients with multiple sclerosis

RESUMO Objetivos: Determinar a freqüência e as características das alterações em exame oftalmológico, em exame de Tomografia de coerência óptica (OCT) do nervo e mácula e Campimetria em pacientes com Escrelose Multipla(EM). Métodos: Foram examinados 60 olhos sendo 30 de pacientes com o diagnóstico de EM e 30 de pacientes controles, atendidos no Hospital de Base do Distrito Federal. Os pacientes foram avaliados quanto aos parâmetros: características e alterações do exame oftalmológico, do OCT do nervo e da macula e Campimetria. Resultados: Os pacientes com EM apresentaram piores resultados em todos os parâmetros avaliados. No exame de campo visual Foram encontradas perdas localizadas em 50%. Em relação ao OCT de nervo óptico foi observado redução da camada de fibras nervosas em quadrantes temporal (p=0,0251) e inferior (p=0,0041), o OCT de mácula revelou diminuição da CFN principalmente nos quadrantes nasal interno (p=0,0002) e externo (p=0,0016),inferior interno (p=0,0007) e superior externo (p=0,0108) e interno (p=0,0046). Os pacientes com menores valores de espessura macular também tiveram piores resultados no campo visual (p=0,0001). Conclusão: Este estudo demonstrou que a EM é uma doença capaz de ocasionar alterações nos exames de OCT e Campo visual mesmo na ausência de sintomas visuais relatados pelos pacientes. A realização de exames como campo visual e de OCT de macula e nervo podem ser uma ferramenta útil para estimar o comprometimento pela doença e auxiliar no seguimento desses pacientes.

ABSTRACT Objectives: To determine the frequency and characteristics of alterations in ophthalmologic examinations of optic nerve and macula coherence tomography (OCT), and Campimetry in multiple sclerosis (MS) patients. Methods: Sixty eyes were examined, 30 of which were diagnosed with MS and 30 of the control patients, all attended at the General Hospital of the Federal District of Brazil. The patients were evaluated regarding the parameters: characteristics and alterations of the ophthalmological examination, OCT of the nerve and macula and Campimetry. Results: Patients with MS presented worse results in all parameters evaluated. On visual field examination localized losses were found in 50% of the cases . In relation to OCT of the optic nerve it was observed a reduction of the nerve fiber layer in temporal quadrants (p = 0.0251) and lower (p = 0.0041). The macular OCT revealed a decrease in the CFN, mainly in the internal nasal quadrants (p = 0.0002) and external (p = 0.0016), internal inferior (p = 0.0007) and external superior (p = 0.0108) plus internal (p = 0.0046). Patients with lower values of macular thickness also had worse results in the visual field (p = 0.0001). Conclusion: This study demonstrated that MS is a disease capable of causing changes in OCT and visual field tests even in the absence of visual symptoms reported by patients. Examinations such as visual field and OCT of macula and nerve can be a useful tool to estimate the damage by the disease and to assist in the follow-up of these patients

Profile of pediatric eye trauma at Hospital de Base do Distrito Federal (HBDF), Brasília, Brazil.

OBJECTIVE: To describe the epidemiological profile of ocular trauma in children at the HBDF emergency department. METHOD: Descriptive, cross-sectional study. We evaluated 103 cases of ocular trauma in children less than 15 years between July 2012 and January 2013. The factors evaluated through semi-structured questionnaire available online were: age, gender, adult supervision, mechanism, type of trauma, time and place, site and nature of injury, visual acuity, need for hospitalization and/or surgery, type of surgery, mother's level of education, and family income. RESULTS: The average age of patients studied was 7.5 years. Boys (68%) predominate in all age groups. Blunt trauma prevailed (55.3%), followed by open (20%). Most of the cases occurred at home, 14 to 20 hours before seeking hospital care. The most common causes were: wood, stone, bicycle, broken glass, and falls. The cornea was affected in 54%. Visual acuity was ≥20/40 in 68.9%. Primary repair of the eye wall was indicated in 70.37% (p-value=0.022). Open traumas were more severe (p-value=0.005) and had more need for intervention (p-value=0.000). The injuries occurred despite the presence of adult supervision in 54% (p-value=0.002). The most severe injuries predominated in the age range 7-15 years (p=0.001). CONCLUSION: Ocular trauma was more frequent among boys. The mechanisms of injury are the most diverse, and prevail at home. Blunt trauma prevails, but the visual impact is due to open trauma. Programs of prevention and education on child ocular trauma are needed.
