Resumo

Objetivo: Avaliar o grau de concordância quanto ao desempenho de leitura com papel branco padrão e papel produzido a partir de cana-de-açúcar.

Métodos: Foi desenvolvido um estudo transversal para comparar quatro versões da cartilha de leitura Byromat-CAO, definidas como PBlack, PNatBlack, PBlue e PNatBlue, de acordo com o tipo de papel (Nat: papel Ledesma, Argentina) e a cor da tinta (preto “Preto” ou azul: “Azul”). A população avaliada foi de oftalmologistas participantes de uma conferência (novembro de 2023). Foram avaliados a acuidade visual para perto (AV), o tempo total de leitura e o número de piscadas. Foi realizado teste de regressão linear de Pearson e o nível de concordância foi analisado pelo teste de Bland-Altman (p<0,05 = estatisticamente significativo).

Resultados: Participaram 104 oftalmologistas com idade média de 39,1 ± 12,4 anos. Não foram encontradas diferenças estatísticas para AV (p: 0,72), obtendo-se correlação positiva (R2:0,83; p: 0,02), com bom nível de concordância na análise de Bland-Altman. Em relação ao tempo total de leitura, na comparação entre grupos independentes, foi observado menor tempo para PNatBlack vs PBlack (p: 0,03) e para PNatBlue vs PBlue (p: 0,04). A frequência de piscadas foi estatisticamente menor (p<0,001) para PNatBlue e PNatBlack.

Conclusões: A acuidade visual para perto foi equivalente entre as quatro variantes, mas o tempo de leitura e a frequência de piscar foram menores com o papel Nat, o que resultou em vantagens para a leitura.
