Exigências visuais e fadiga visual em médicos oftalmologistas

Abstract

ARTIGO ORIGINAL RESUMO | 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.

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 nee...

Randomized trial comparing the effects of a 3D head-up system and microscope eyepiece-assisted simulated vitrectomy with intraocular illumination on the ocular surface of an operator

“…However, in daily clinical practice, the cumulative time to perform vitrectomy is much longer than 2 h, which may increase the risk of abnormal ocular surface tissue. Previous studies have shown that the professional activities that ophthalmologists engage in for long time periods, including the application of computers, microscopes and slit lamps, can decrease blink frequency [ 11 ]. Yan et al showed that increasing amounts of high-intensity work performed by ophthalmologists lead to considerable alterations in tear dynamics, which can cause dry eye [ 15 ].…”

“…It has been shown that ophthalmologists inevitably experience a decrease in the blink rate when using slit lamps or surgical microscopes, which may lead to changes in tear secretion [ 11 ]. The 3D head-up system differs significantly from the microscope eyepiece system in terms of intraocular illumination, operative field presentation, working distance, and surgical posture.…”

Effect of auricular acupressure combined with acupuncture for juvenile pseudomyopia

“…The inclusion criteria were as follows: All children were diagnosed with JPM based on the diagnostic standard of pseudomyopia adopted from the diagnostic standard of Theory and Methods of Optometry [ 28 ] ; age between 6 and 11 years; and Presence of blurred distance vision and susceptibility to visual fatigue. [ 29 ]…”

A Insuficiência De Convergência

“…Esse processo é instintivamente exercido pelas pessoas para a manutenção da visão binocular, adquirindo assim uma importância clínica (DUKE-ELDER, 1997). No mundo contemporâneo, a presença quase onipresente dos dispositivos computacionais como smartphones, computadores, e-readers, entre outros, criam a necessidade do uso da visão para atividades diárias mais próxima aos olhos, necessitando assim da atenção visual para a execução de tais atividades (DZHODZHUA et al, 2017). Os autores ainda refletem que o microclima e a iluminação também podem influenciar o sistema visual.…”
