O Presente trabalho teve por finalidade fazer uma revisão bibliográfica acerca do
tema, a avaliação da visão das cores e os vários sistemas de análise do teste Farnsworth
Munsell 100-Hue. Foram avaliadas várias publicações nacionais e internacionais,
seleccionadas de forma criteriosa quanto ao material e método utilizados e que se
adequassem e satisfizessem os objectivos desta revisão bibliográfica. Foram encontrados na
totalidade 877 documentos, dos quais apenas 46 foram analisados, segundo os critérios de
selecção. Concluiu-se que o método de análise mais utilizado é a análise quadrante.
Os defeitos na visão cromática podem ser divididos em duas grandes classes: defeitos
congénitos e defeitos adquiridos. Entender e diferenciar estas duas condições é importante na
prática clínica, tanto para diagnóstico dos defeitos congénitos, como para diagnóstico e
acompanhamento dos defeitos adquiridos.
Actualmente estão disponíveis diversos testes clínicos que podem ser aplicados no
diagnóstico das discromatopsias, porém, é necessário conhecerem-se as vantagens de uns em
relação aos outros, bem como a fiabilidade dos seus resultados, para que se possa seleccionar
a melhor ferramenta de trabalho na hora de avaliar a visão das cores. Os testes de visão das
cores são usados para os mais diversos fins, desde a simples triagem, passando pela
diferenciação e qualificação do tipo de defeito até a orientação vocacional.
De entre a diversidade de testes disponíveis no mercado para a avaliação dos defeitos
cromáticos, só alguns permitem quantificar a severidade do defeito, sendo o teste das 100
tonalidades de Farnsworth Munsell (FM-100), o mais utilizado. Os defeitos adquiridos são
melhor reproduzidos pelo teste de FM-100, mas na maioria das vezes, os resultados revelam
um padrão pouco característico de defeito. Dada a grande dificuldade na diferenciação de
discromatopsias congénitas de adquiridas, nos últimos tempos, várias propostas de análise de
resultados têm sido apresentadas para a análise deste teste, como alternativas à análise
convencional.
The present paper aims to systematically review the literature on the subject of evaluation of colour vision and the various test systems for analyzing the Farnsworth-Munsell 100. We evaluated several national and international publications, judiciously selected as the material and method used and that fit and met the objectives of this systematic review. Found 877 documents in total, of which only 46 were analyzed according to the selection criteria. It was concluded that the most widely used analysis’ method is the quadrant’s analysis. Colour vision defects can be divided into two major categories: birth defects and acquired defect. Understand and differentiate these conditions is important in clinical practice, both for diagnosis of defects, as for diagnosis and monitoring of acquired defects. Currently several clinical trials are available that can be applied for diagnosis of color blindness, however, you need to know the advantages of one over the other, and the reliability of their results, so you can select the best working tool time to evaluate color vision. Tests for color vision are used for different purposes, ranging from simple screening, through differentiation and determination of the type of defect to the vocational orientation. Among the variety of commercially available tests for the evaluation of chromatic defects, only a few can be used to quantify the severity of the defect, and the testing of 100 shades of Fransworth Munsell 100-Hue is the most used. The acquired defects are best reproduced by the FM-100 test, but in most cases, the results reveal a pattern uncharacteristic of defect. Given the great difficulty in differentiating congenital from acquired color blindness, at the last time, several proposals for analysis of results have been presented for the analysis of this test, as alternatives to conventional analysis.
