- Eye discomfort at close work in Portuguese university students: A comparative analysis between the pre-COVID and confinement periodPublication . Nunes, Amélia Fernandes; Leitão, Mara Filipa Antunes; Nunes, António; Monteiro, PedroBackground Many individuals experience visual symptoms associated with near work. The level of discomfort appears to increase with the amount of digital screen use. Objective To study the eye discomfort with near tasks in university students in the pre-COVID period and in the period of confinement due to the pandemic. Methods Two independent samples of students, aged between 18 and 35 years, were used to assess symptomatic behaviour with the Convergence Insufficiency Symptom Survey (CISS) questionnaire. In the pre-COVID period the sample had 342 participants, 64.6% females and in the COVID period 322 students participated, 71.4% females. The study of differences was carried out by the Mann-Whitney U test. The interpretation of the statistical inference was performed for a significance level≤0.05. Results There was an increase in the number of symptomatic cases in the COVID period without statistical evidence of differences in the frequency of symptoms reported in the two periods. The dimensions "somatic sensations" and "cognitive performance" were the typology of symptoms that most contributed to visual complaints with near vision. There was a significantly different symptomatic behaviour between genders in the period of confinement (p = 0.001), worsening in females and improving in males. Conclusion These findings suggest that females and males exposed to digital environments, over time, may exhibit different symptomatic behaviour. Our results suggest that boys adapt more quickly than girls. Factors that predispose to these changes, aetiology and potential intervention actions still need further study.
- Adaptação do Questionário Standardized Patient Evaluation of Eye Dryness para Português (SPEED-Vp) numa População Não ClínicaPublication . Sanches, Ana Lúcia; Leite, Sara Gisela; Nunes, António; Caixinha, Miguel; Monteiro, Pedro; Nunes, AméliaIntrodução: O objetivo deste estudo foi traduzir e adaptar o questionário Standardized Patient Evaluation of Eye Dryness para o português europeu, bem como avaliar o desempenho psicométrico da versão traduzida, incluindo repetibilidade e concordância. Material e métodos: O questionário original Standardized Patient Evaluation of Eye Dryness - SPEED foi traduzido e adaptado para o contexto cultural português seguindo uma metodologia cientificamente válida comumente usada no processo de adaptação de instrumentos para outras culturas e línguas. O questionário resultante da tradução para o novo idioma foi sujeito a um pré-teste onde os comentários dos participantes foram escritos e considerados para a versão final do questionário. Para a validação da escala da versão final do questionário traduzido, 89 indivíduos de uma população não clínica, com idades entre 18 e 84 anos, foram convidados a responder ao questionário (61% eram mulheres). Uma semana depois, o mesmo questionário foi repetido por 63 indivíduos. A confiabilidade interna do questionário foi analisada pelo alfa de Cronbach, a estabilidade temporal pelo teste-reteste e a análise de concordância entre medidas pelo método de Bland-Altman. Resultados: A consistência interna do questionário traduzido, SPEED-vP, foi alta (α = 0,871) e todos os itens do questionário contribuíram para o aumento desse índice. Essa consistência também foi confirmada como alta no reteste (α = 0,856) e quando a amostra foi estratificada por idade e sexo. O questionário SPEED-complete também apresentou alta consistência (α = 0,88). A repetibilidade do instrumento foi alta (ICC 0,933; IC 95%: 0,899 e 0,960) e o gráfico de Bland-Altman revelou boa concordância entre as medidas. Conclusão: O Standardized Patient Evaluation of Eye Dryness in Portuguese (SPEED-vP) apresentou boas propriedades psicométricas para a população portuguesa. Portanto, a versão traduzida do questionário SPEED-vP pode ser usada para mensurar quantitativamente a presença de sintomas de olho seco na população portuguesa.
- Convergence insufficiency and accommodative insufficiency in childrenPublication . Nunes, Amélia; Monteiro, Pedro; Brardo, Francisco M.; Nunes, AntónioPurpose: Convergence and accommodative insufficiency represent the main cause of complaints during close visual work and can reduce visual performance and comfort. Knowing their prevalence among schoolchildren is fundamental to define strategies for action. The purpose of this study was to estimate the frequency of these conditions in children in 5th and 6th school years in inland Portugal and to assess the impact that each visual condition has on their quality of life, based on the level of visual symptoms. Methods: a cross-sectional study was carried out with children enrolled in the 5th and 6th school years. 372 children (192 girls) were assessed, with average ages of 10.9 ± 0.9 years. Refractive error and binocular vision assessment, integrating accommodative parameters, were used to analyse the visual condition. Symptoms were quantified using the Portuguese version of the CISS (Convergence Insufficiency Symptom Survey). Results: The prevalence of definite Convergence Insufficiency (CI) in the children assessed was 2%. A prevalence of 6,8% could be considered if clinically significant CI (high suspect and definite categories) cases are accounted. In relation to Accommodative Insufficiency (AI), a frequency rate of 10% was recorded, with 3% of the evaluated children presenting AI and CI simultaneously. The symptoms score was higher in AI than in CI. Conclusions: A frequency of approximately 10% was found for each one of the visual syndromes, and it was verified that visual discomfort is common among teenagers who carry these conditions. In cases of asthenopia, such as headaches and loss of concentration, associated with near vision activities, there is a requirement to evaluate the quality of binocular vision.
