Acuidade visual

Exames: saiba mais!

acuidade visual (AV) trata-se de quando o olho reconhece dois pontos muito próximos uns dos outros, tornando a visão incômoda e a pessoa sente dificuldade em enxergar formas e contornos dos objetos. A distância entre foto-receptores na retina e da precisão da refração é o que causa a acuidade visual. Para medir a acuidade visual é preciso avaliar a relação entre o tamanho do menor objeto visualizado e a distância entre o individuo e objeto, dados que valerão para analisar a gravidade da patologia. A acuidade visual pode ser tratada com o uso de lentes corretivas, comolentes de contato, implantes de lentes intra-oculares e óculos de grau, quando for de nível baixo. Estes indivíduos podem não ter sua vida útil prejudicada pelo problema de visão.
