Uso da tonometria de ar em pesquisas populacionais - comparação com o tonômetro de Goldmann em indivíduos com suspeita de hipertensão ocular

Abstract

RESUMO Objetivo: Avaliar a utilidade do tonômetro de ar (TA) em estudos populacionais em indivíduos suspeitos de hipertensão ocular, comparando os valores com os fornecidos pelo tonômetro de aplanação de Goldmann (TG). Métodos: Estudo transversal, de amostra probabilística, composta por 11.452 indivíduos e"20 anos, compondo-se uma subamostra dos que apresentaram valores de pressão intraocular (PIO) obtidos com o TA e"20mmHg, nos quais a PIO foi repetida com o TG. Os resultados dos dois tonmetros foram comparados considerando sexo, cor da pele referida, lateralidade, relação escavação/disco (Â0,6; entre e"0,6 e <0,8; e"0,8) e diagnóstico. Foram consideradas três situações: não-portadores de glaucoma (NG), suspeitos (SG) e portadores de glaucoma (CG). Para comparação entre as medidas foi utilizado o teste t de Student para amostras pareadas e o teste de correlação de Pearson para avaliar a associação entre PIO, idade e tonometria. Resultados: Foram detectados 198 indivíduos (339 olhos) com PIOe"20mmHg com o TA, que tiveram a medida repetida com o TG. Foram considerados 233 olhos como NG, 47 olhos como SG e 19 olhos como CG. Em olhos com escavação e"0,8, a medida com TA e TG foram semelhantes. Nos NG e SG, o TA superestimou os valores. Houve associação entre aumento da PIO e aumento da idade com os dois tonmetros. Conclusão: Valores de PIO são superiores com TA comparados ao TG, principalmente quando a PIO é normal. Há concordância entre os métodos quando a PIO é alta e a escavação do nervo óptico é aumentada, o que valida a aplicação do TA em campanhas populacionais.
