Introducción: El uso excesivo de las redes sociales ha generado diversas secuelas en la salud mental y visual-ocular, dando lugar al Síndrome Visual Informático (SVI) por sobreexposición a las pantallas. Objetivo: Analizar la influencia del uso de las redes sociales en el síndrome visual informático en adolescentes en una realidad peruana. Métodos: Se realizó una investigación de enfoque cuantitativo, hipotético-deductivo, transaccional, correlacional-causal, con una muestra de 126 adolescentes. Para recabar información acerca del uso de las redes sociales, se utilizó el ARS de Escurra y Salas. Para verificar la prevalencia del SVI, se empleó el Cuestionario de Síndrome Visual Informático de Seguí y colaboradores; ambos instrumentos fueron adaptados a formato Google Forms para su aplicación en línea. Resultados: Se encontró una asociación significativa entre el tiempo de permanencia en las redes sociales (RS) y el SVI (p=0,027<0,05); además, se evidenció el impacto significativo de la Adicción a las Redes Sociales (ARS) sobre el SVI (p=0,000<0.01), los síntomas visuales (p=0,000<0.01), oculares (p=0,000<0.01) y astenópicos (p=0,003<0.01). Conclusiones: El estudio demuestra una clara conexión entre el uso excesivo de redes sociales y el SVI en adolescentes peruanos, subrayando la necesidad de una acción conjunta de padres y educadores para mitigar los riesgos y promover un uso digital saludable(AU)

OBJECTIVE@#To compare the clinical efficacy between Wei's triple nine needling combined with esculin and digitalis glycosides eye drops and esculin and digitalis glycosides eye drops alone for presbyopia complicated with visual fatigue of liver depression and spleen deficiency.@*METHODS@#Forty-six cases (92 eyes) with presbyopia complicated with visual fatigue of liver depression and spleen deficiency were randomly divided into an observation group (23 cases) and a control group (23 cases, 2 cases dropped off). The cases in the observation group were treated with Wei's triple nine needling and esculin and digitalis glycosides eye drops. The acupoints included Shangming (Extra), Chengqi (ST 1), Cuanzhu (BL 2) to Jingming (BL 1), Sizhukong (TE 23) to Taiyang (EX-HN 5), etc; the needling was given once every other day, three times a week, and the eye drops were given one drop each time, three times a day. The cases in the control group were only treated with the eye drops. Both groups were treated for 7 days as one course of treatment, and 2 courses of treatment were given. The visual fatigue core symptoms score, adjustment amplitude, adjustment lag and best average corrected visual acuity were observed in the two groups before treatment, 1 week and 2 weeks into treatment, respectively.@*RESULTS@#Compared before treatment, the visual fatigue core symptoms scores in the two groups were decreased after 1-week and 2-week treatment (P<0.05); in the observation group, the adjustment amplitude was increased after 2-week treatment (P<0.05), while in the control group, the adjustment amplitude was increased after 1-week and 2-week treatment (P<0.05); in the observation group, the adjustment lag was decreased after 1-week and 2-week treatment (P<0.05). After 2-week treatment, the visual fatigue core symptoms score in the observation group was lower than that in the control group, and the adjustment amplitude was higher than that in the control group (P<0.05). There were no significant differences in adjustment lag and best average corrected visual acuity between the two groups after 1-week and 2-week treatment (P>0.05).@*CONCLUSION@#Wei's triple nine needling combined with esculin and digitalis glycosides eye drops could improve the visual fatigue and eye regulation ability in patients with presbyopia complicated with visual fatigue of liver depression and spleen deficiency, and the effect is better than esculin and digitalis glycosides eye drops alone.

RESUMO Objetivo: Avaliar sintomas astenópicos e fatores sociodemográficos, hábitos comportamentais e clínicos nos docentes universitários durante a pandemia da COVID-19. Métodos: Trata-se de estudo transversal que avaliou a ocorrência de astenopia em 104 docentes. Questionários de sintomatologia visual validados foram adaptados para a coleta de dados. Houve comparação dos docentes quanto à ocorrência ou não de sintomas astenópicos, bem como foi aplicada regressão logística binária, para aferir a associação com variáveis independentes (p<0,05). Resultados: Houve maior aparecimento de sintomas astenópicos durante o período pandêmico, em que o tempo de exposição a telas parece ter sido o fator mais determinante. Além disso, os indivíduos com tempo de tela superior a 5 horas diárias, que faziam uso de telas para o lazer e usavam colírio/lubrificantes apresentaram significativamente maior chance de estar no grupo com sintomas astenópicos. Conclusão: Foi identificada associação significativa entre a ocorrência de sintomas astenópicos e o uso de telas durante o período pandêmico, principalmente nos grupos com maior duração do tempo de tela. O estudo chama atenção para a saúde ocular de docentes universitários em ensino remoto, além de suscitar novos estudos para investigação desse quadro em distintos ambientes escolares.
ABSTRACT Objective: To assess asthenopic symptoms and sociodemographic factors, behavioral and clinical aspects in college lecturers during the COVID-19 pandemic. Methods: This is a cross-sectional study evaluating asthenopia in 104 lecturers. Some validated visual symptom questionnaires were adapted for data collection. Lecturers were compared regarding the occurrence or not of asthenopic symptoms, and binary logistic regression was applied to measure the association with independent variables (p<0.05). Results: Asthenopic symptoms occurred more often during the pandemic, when exposure to screens was a determinant factor. The individuals with screen time longer than five hours a day, who used screens for leisure, and who used eye drops/lubricants were significantly more likely to be in the group with asthenopic symptoms. Conclusion: A significant association was identified in occurrence of asthenopic symptoms and screen use during the pandemic period, especially in groups with longer screen time. The study draws attention to the eye health of college lecturers in distance learning, and the need for further research on this situation in different school environments.

ABSTRACT Purpose Evaluate blue-violet light filter and additional power of +0.40 D in the near zone ophthalmic lenses, on convergence, accommodative functions, and symptoms of digital asthenopia (DA). Methods Randomized study in cross-over design conducted on 49 volunteers (age, 29 ± 5.5 years; male: female, 18:31). Each subject wore test (+0.40 D in the near zone) and control lenses (regular single vision) for 4 weeks in randomized order. Both lenses had a selective blue-violet light filter. A baseline measurement was taken with the subjects' current updated glasses. Accommodation amplitude (AA) and near point of convergence (NPC) were measured binocularly with the RAF ruler. DA was evaluated by a questionnaire. Results No significant difference (p=.52) was found for AA comparing baseline (11.50±1.88 D), test (11.61± 1.62 D), and control SV lenses (11.88±1.50 D). No significant difference was found for NPC (p=.94), between baseline (6.50 ± 2.89cm), test (6.71± 3.49) and control SV lenses (6.82± 3.50 cm). No significant difference was found comparing test and control SV lenses in symptoms of DA (p=0.20). Conclusions The +0.40 D lenses have no negative impact on convergence or loss of accommodation power. The +0.40 D and control SV lenses had a similar impact on attenuating symptoms of DA.
RESUMO Objetivo Avaliar os efeitos do uso de lentes oftálmicas com filtro seletivo de luz azul-violeta, sem e com poder adicional de + 0,4D na zona de perto nas funções de acomodação e convergência e para sintomas de astenopia digital (AD). Métodos Ensaio clínico controlado, randomizado e mascarado, com 49 voluntários (idade, 29 ± 5,5 anos; masculino: feminino, 18: 31). Cada participante usou lentes de teste (+0,40 D na zona de perto) e controle (visão simples), por 4 semanas de forma randomizada. Ambas as lentes tinham filtro seletivo de luz azul-violeta. A medição inicial (baseline) foi feita com os óculos atualizados de cada participante. A amplitude de acomodação (AA) e o ponto de convergência próximo (PPC) foram medidos binocularmente com a régua RAF. A AD foi avaliada por um questionário. Resultados Não houve diferença estatisticamente significante (p=0,52) para as medidas de AA comparando as lentes baseline (11,50±1,88 D), teste (11,61±1,62 D) e controle VS (11,88±1,50 D). Nenhuma diferença significativa foi encontrada para a medida do PPC (p=0,94), entre as lentes baseline (6,50 ± 2,89cm), teste (6,71±3,49) e controle VS (6,82±3,50 cm). Nenhuma diferença significativa foi encontrada comparando lentes teste de VS e controle nos sintomas de AD (p=0,20). Conclusões As lentes com +0,40 D não têm impacto negativo na convergência ou na perda de acomodação. As lentes +0,40 D e controle VS, tiveram impacto semelhante na redução dos sintomas de AD.

La lucha epidemiológica contra la pandemia COVID-19 ha incluido medidas sociales como el confinamiento y el cierre de actividades laborales y académicas. A consecuencia, tareas que se llevaban a cabo en el contexto presencial debieron ser ejecutadas desde los hogares, adoptando estrategias como el teletrabajo y la educación virtual, haciendo necesario el uso de herramientas como ordenadores y laptops. De allí que las personas han incrementado la exposición a las pantallas de dispositivos electrónicos, como son computadoras y laptops, trayendo como consecuencia afectaciones en la salud visual de las personas tales como el síndrome visual informático (SVI). Se realizó un estudio transversal con el objetivo de determinar la afectación por SVI en la población peruana y su relación con la exposición prolongada a DEV, generada a raíz de las medidas sociales de enfrentamiento a la pandemia de COVID-19. El tiempo promedio en que los sujetos de nuestro estudio usaron DEV dentro de los hogares se acrecentó un 120%, es decir 4,26±2,36 horas diarias adicionales al comparar con el año anterior a la pandemia COVID-19. La adopción masiva de actividades como el teletrabajo y la educación virtual podrían explicar el hecho que los grupos de empleados/patronos y estudiantes fueron los mayores usuarios de DEV, con 10,41 y 9,32 horas diarias. De acuerdo a los hallazgos obtenidos, es estadísticamente válido afirmar que las medidas sociales para enfrentar la pandemia COVID-19 indujeron al aumento en la prevalencia de SVI en los pobladores peruanos (p<0,001). En la actual investigación, la proporción de individuos que manifestaron SVI pasó de 38 a 64%, antes y durante la aplicación de las medidas, respectivamente(AU)
The epidemiological fight against the COVID-19 pandemic has included social measures such as confinement and the closure of work and academic activities. As a consequence, tasks that were carried out in the face-to-face context had to be carried out from homes, adopting strategies such as teleworking and virtual education, requiring the use of tools such as computers and laptops. Hence, people have increased exposure to the screens of electronic devices, such as computers and laptops, resulting in effects on people's visual health such as computer vision syndrome (SVI). A cross-sectional study was carried out in order to determine the affectation by SVI in the Peruvian population and its relationship with prolonged exposure to DEV, generated as a result of social measures to cope with the COVID-19 pandemic. The average time in which the subjects in our study used DEV within homes increased by 120%, that is, 4.26 ± 2.36 additional daily hours when compared to the year before the COVID-19 pandemic. The massive adoption of activities such as teleworking and virtual education could explain the fact that groups of employees / employers and students were the largest users of DEV, with 10.41 and 9.32 hours per day. According to the findings obtained, it is statistically valid to affirm that the social measures to face the COVID-19 pandemic induced an increase in the prevalence of SVI in the Peruvian population (p <0.001). In the current investigation, the proportion of individuals who manifested SVI went from 38 to 64%, before and during the application of the measures, respectively(AU)

Los ojos son el foco principal de la cara y se les atribuye la expresión de la personalidad del individuo. La configuración anatómica de los párpados y de la región periorbitaria conforma una de las áreas más importantes de la expresión humana. Existen alteraciones aparentemente estéticas que llevan a trastornos visuales, como la dermatocalasis y blefarochalasis, que limitan el campo visual o provocar fatiga ocular por la presión de la piel redundante sobre los párpados, la laxitud de los tendones cantales origina un síndrome de exposición escleral y a la vez lagrimeo. La blefaroplastia produce resultados clínicos y estéticos favorables en los pacientes aquejados por esta patología.
The eyes are the main focus of the face and the expression of the individual's personality is attributed to them. The anatomical configuration of the eyelids and the periorbital region constitutes one of the most important areas of human expression. There are apparently aesthetic alterations that lead to visual disorders, such as dermatochalasis and blepharochalasis, which can limit the visual field or cause eye fatigue due to the redundant pressure of the skin on the eyelashes, the laxity of the canthal tendons causes a scleral exposure syndrome and at the same time tearing. Blepharoplasty produces favorable clinical and aesthetic results in patients suffering from dermatochalasis.

RESUMO A função de controlador aéreo exige várias horas de visualização de ecrãs, o que torna esses profissionais um grupo particularmente exposto à astenopia digital. Procuramos, com este artigo de revisão, compreender quais os métodos quantitativos e qualitativos usados atualmente para diagnosticar e avaliar a fadiga ocular em controladores de tráfego aéreo. Trata-se de pesquisa bibliográfica utilizando as bases de dados PubMed® e ClinicalKey®, usando palavras-chave, tendo sido selecionados artigos de revisão e estudos observacionais com publicação posterior ao ano 2000, de modo que os termos buscados estivessem no título e/ou resumo do trabalho. Excluímos artigos em línguas que não inglesa. Existem vários métodos para melhor caracterizar a astenopia digital, destacando-se os subjetivos, como questionários, e os objetivos, que procuram, por um lado, diagnosticar o olho seco, bem como alterações da acomodação e da convergência. Da análise efetuada, ressaltou-se uma escassez de estudos prospectivos com Níveis de Evidência moderados e altos relacionados com a aplicação dos vários métodos de diagnóstico. A Computer-Vision Symptom Scale parece ser um questionário confiável e que pode ser aplicado aos controladores de tráfego aéreo, para diagnóstico de astenopia digital. Vários métodos objetivos podem também ser utilizados para essa avaliação, sendo importante, numa fase posterior, aplicar esses dois tipos de métodos de diagnóstico para avaliar a prevalência dessa patologia em controladores de tráfego aéreo.
ABSTRACT The work of air traffic control specialists require several hours looking at screens, and they comprise a group particularly exposed to digital-related eye strain. In this review we aim to understand the quantitative and qualitative methods currently used to diagnose and evaluate asthenopia in air traffic control specialists. A bibliographic search was carried out at the databases PubMed® and ClinicalKey®, using keywords, and selecting review articles and observational studies, dated after 2000, containing the keywords in the title and/o abstract. Articles not published in English were excluded. There are several subjective and objective methods to better describe digital-related eye strain, including questionnaires, aiming to make diagnosis of dry eye disease or changes in accommodation and convergence. From our analysis, there are few prospective studies with moderate and high levels of evidence regarding these diagnostic methods. The Computer-Vision Symptom Scale seems to be a reliable questionnaire to be applied to air traffic control specialists, for diagnosis of digital-related eye strain. Several objective methods can also be employed in this evaluation, and, in a later stage, it will be important to apply both diagnostic methods to evaluate the prevalence of this condition in air traffic control specialists.

PURPOSE: To investigate ocular fatigue after the use of a head-mounted display (HMD)-type virtual reality device.METHODS: Healthy adult volunteers were examined for ocular fatigue before and after watching videos for 10 min with an HMD-type virtual reality device. Subjective ocular fatigue was measured using a questionnaire. Objective fatigue was measured using the critical flicker fusion frequency (CFF), high frequency component of accommodative microfluctuation, and accommodation amplitude. The accommodation amplitude was measured using the push-up method and the dynamic measurement mode of the autorefractometer. Changes in the spherical equivalent were also measured.RESULTS: The questionnaire-based subjective ocular fatigue increased (p = 0.020) after use of the HMD device. In the dominant eye, the high frequency component of accommodative microfluctuation increased (p < 0.05). The accommodation amplitude using the push-up method was decreased in the nondominant eye (p = 0.007), and temporary myopia was observed (p < 0.05). However, there was no increase in ocular fatigue in the CFF or the accommodation amplitude using the dynamic measurement mode, which showed no significant difference before and after using the HMD device (p > 0.05).CONCLUSIONS: A subjective test and some objective tests suggested that use of the HMD-type virtual reality display increased ocular fatigue. However, no increase in ocular fatigue was measured using CFF nor in the accommodation amplitude using the dynamic measurement mode which was a limitation of the study. More studies with the aim to alleviate ocular fatigue after using HMD-type virtual reality devices are therefore needed.

OBJECTIVE@#To compare the therapeutic effects on the relevant symtoms in the patients with dry eye syndrome treated with the acupoint thread-embedding therapy versus topical artificial tears eye drops.@*METHODS@#A total of 88 patients with dry eye syndrome of deficiency lacrima production were randomized into an acupoint thread-embedding therapy group (thread-embedding group) and a control group with topical artificial tears eye drops (medication group), 44 cases in each one. In the thread-embedding group, 3 cases were dropped out. In the thread-embedding group, Ganshu (BL 18), Pishu (BL 20) and Shenshu (BL 23) etc. were selected and the acupoint thread-embedding therapy was operated once every 30 days, totally for two treatments. In the medication group, the topical artificial tears eye drops was used, 4 to 6 times a day, one drop each time, for 8 weeks totally. Separately, before treatment, after 4-week treatment and 8-week treatment as well as in 8 weeks and 12 weeks of the follow-up, the levels of lactoferrin in tears were determined and the scores of the relevant symptoms of ocular surface such as eye dryness, foreign body sensation in the eyes and eye fatigue were evaluated.@*RESULTS@#In the thread-embedding group, after 4-week and 8-week of treatment as well as in 8-week and 12-week follow-up, the scores of eye dryness, foreign body sensation, burning sensation of eye, phengophobia and eye fatigue were reduced significantly as compared with those before treatment (all 0.05). The levels of lactoferrin in tears at each time point after treatment in the thread-embedding group were higher than the medication group (<0.05).@*CONCLUSION@#The acupoint thread-embedding therapy effectively improves in the relevant symptoms of ocular surface, such as eye dryness, foreign body sensation, burning sensation of eye, phengophobia and eye fatigue, and increases the level of lactoferrin in tears in the patients with dry eye syndrome of deficiency aqueous production. In the follow-up, the therapeutic effects of the acupoint thread-embedding therapy are significantly better than artificial tears eye drops.

BACKGROUND: To investigate the influence of nocturnal ambient light on visual function and ocular fatigue. METHODS: Sixty healthy subjects (30 men and 30 women) aged 19 through 29 years with no history of ocular disease were recruited. All subjects spent 3 consecutive nights in the sleep laboratory. During the first and second nights, the subjects were not exposed to light during sleep, but during the third night, they were exposed to ambient light, measuring 5 or 10 lux at the eye level, which was randomly allocated with 30 subjects each. The visual function and ocular fatigue were assessed at 7 a.m. on the 3rd and 4th mornings, using best-corrected visual acuity, refractive error, conjunctival hyperemia, tear break-up time, maximal blinking interval, ocular surface temperature, and subjective symptoms reported on a questionnaire. RESULTS: Three men and three women subjects failed to complete the study (4 in the 5 lux; 2 from the 10 lux). For the entire 54 subjects, tear break-up time and maximal blinking interval decreased (P = 0.015; 0.010, respectively), and nasal and temporal conjunctival hyperemia increased significantly after sleep under any ambient light (P < 0.001; 0.021, respectively). Eye tiredness and soreness also increased (P = 0.004; 0.024, respectively). After sleep under 5 lux light, only nasal conjunctival hyperemia increased significantly (P = 0.008). After sleep under 10 lux light, nasal and temporal conjunctival hyperemia, eye tiredness, soreness, difficulty in focusing, and ocular discomfort increased significantly (P < 0.05). CONCLUSION: Nocturnal ambient light exposure increases ocular fatigue. Avoiding ambient light during sleep could be recommended to prevent ocular fatigue.

BACKGROUND: On-call work is a form of work that requires the person to work at any time during the on-call period. Thus, on-call work is often regarded as one of the most severe stress factors. This study investigates the associations between on-call work and health problems, injuries. METHODS: This study was based on the 3rd Korean Working Conditions Survey. Total of 29,246 employed workers who had been working for at least 1 year were included. Logistic regression analysis was performed to investigate the association between on-call work and health problems, injuries. RESULTS: The odds ratios for on-call workers in terms of physical health problems, psychological health problems, and injuries were 1.33 (95% confidence interval [CI] 1.22-1.44), 1.31 (95% CI 1.08-1.60), and 2.76 (95% CI 2.26-3.37), respectively. Analysis of the detailed symptoms revealed odds ratios in on-call workers of 2.06 for hearing problems (95% CI 1.63-2.62); 1.71 for skin problems (95% CI 1.38-2.12); 1.22 for back pain (95% CI 1.08-1.38); 1.23 for muscular pains in upper limbs (95% CI 1.12-1.34); 1.27 for muscular pains in lower limbs (95% CI 1.15-1.40); 1.46 for headache, eye fatigue (95% CI 1.32-1.60); 1.37 for abdominal pain (95% CI 1.02-1.85); 1.43 for depression or anxiety disorders (95% CI 1.07-1.93); 1.36 for fatigue (95% CI 1.24-1.49); and 1.41 for insomnia and general sleep difficulties (95% CI 1.13-1.76). CONCLUSIONS: The present study found that on-call work results in an increased risk of health problems and injuries. This study is the result of analyses of broad range of the job spectrum in Korean employed workers; thus, future studies are necessary to determine the effects of on-call work in various job groups.

Contexto: As exigências visuais, designadamente da visão ao perto, são cada vez mais frequentes no mundo do trabalho, podendo causar fadiga visual ou astenopia. Os médicos oftalmologistas exercem atividades que exigem esforço visual, o que determina o interesse no seu estudo pela saúde ocupacional. Objetivos: Identificar a prevalência das queixas visuais e a sua relação com as exigências do trabalho nos médicos oftalmologistas em um hospital universitário de Lisboa. Métodos: Avaliou-se a ocorrência de sintomas de fadiga visual por meio de um questionário de sintomas Inventário de Eficiência Visual (IEV) e pela determinação dos pontos próximos de acomodação e de convergência. Utilizou-se o teste de Schirmer para a avaliação da secreção lacrimal. Os resultados foram analisados com o auxílio da estatística descritiva, do coeficiente de Spearman e do teste de Wilcoxon para p<0,05. Resultados: Dos 27 médicos respondentes, a maioria refere fadiga visual (n=25), assim como a presença de olhos secos e o piscar frequentemente (n=27). Os resultados do teste de Shirmer evidenciam diferenças no final do dia de trabalho e os pontos próximos de acomodação e convergência evidenciam a presença de fadiga visual. Conclusões: Os resultados revelaram diferenças significativas entre o início e o final do dia de atividade profissional dos médicos oftalmologistas, indiciando a existência de fadiga visual ao final do dia de trabalho. Tal situação determina a necessidade de implementar um programa de vigilância da saúde para prevenir alterações visuais de natureza profissional.
Background: Visual demands, especially for near vision, are becoming increasingly more frequent at the workplace, and might cause visual fatigue or asthenopia. The tasks performed by ophthalmologists involve visual effort, raising interest in their study within the context of occupational health. Objectives: To estimate the prevalence of visual complaints and its relationship to work demands among ophthalmologists at a university hospital in Lisbon. Methods: Occurrence of visual fatigue symptoms was assessed by means of a symptom questionnaire College of Optometrists in Vision Development Quality of Life (COVD-QoL) and through the identification of near points of accommodation and convergence. Schirmer's test was used to assess tear production. The results were analyzed by means of descriptive statistics, Spearman's coefficient and the Wilcoxon test for p<0.05. Results: Most among the 27 analyzed physicians reported visual fatigue (n=25), dry eyes and frequent blinking (n=27). Schirmer's test evidenced differences at the end of the working day and the near points of accommodation and convergence indicated occurrence of visual fatigue. Conclusions: The results showed significant differences between the beginning and the end of the working day among ophthalmologists, with occurrence of visual fatigue at the end of the working day. These findings point to the need to implement a health surveillance program to prevent occupational visual disorders.
