Espessura central da córnea e a medida da pressão intra-ocular com diferentes tonômetros

Abstract

OBJETIVO: Analisar a possivel variacao da pressao intra-ocular, obtida por diferentes tonometros, com a espessura central da cornea. METODOS: Apos a medida da pressao intra-ocular com o ICare, instilou-se uma gota de colirio anestesico e fez-se a medida da espessura da cornea e, tambem, a medida da pressao intra-ocular com o tonometro de contorno dinâmico de Pascal. Em seguida, instilou-se uma gota de colirio de fluoresceina e mediu-se a pressao intra-ocular o tonometro de aplanacao de Goldmann. RESULTADOS: 138 olhos de 71 pacientes foram examinados e divididos em 3 grupos de acordo com a espessura central da cornea. A analise da pressao intra-ocular mostrou valores concordantes quando se utilizou o ICare e o tonometro de contorno dinâmico de Pascal, com media de diferenca de -0,2. A pressao intra-ocular medida com o tonometro de contorno dinâmico de Pascal apresentou valores maiores que os obtidos com o tonometro de aplanacao de Goldmann, com media de diferenca de -3,1. Uma diferenca estatisticamente significante foi obtida nas medidas com o ICare e tonometro de aplanacao de Goldmann. CONCLUSAO: Existe uma diferenca estatisticamente significante entre os valores da PIO obtidos com ICare, tonometro de contorno dinâmico de Pascal e tonometro de aplanacao de Goldmann, quando relacionados com a espessura central da cornea.
