Abstract

Abstract: : Purpose: To compare the acting of the HRT II in the glaucoma diagnosis. Methods: 100 patients were attended in Glaucoma consultation. All of them carried out a complete ophthalmological exam, visual field Humphrey 24-2 SITA Standard and HRT II. The diagnostic gold standard of Glaucoma was defined as positive exam clinical plus visual field. The data were analyzed with the program STATA 6.0 Results: 51 patients had diagnosis of glaucoma according to the Gold Standard. The average age was 56 years (17-84 years) and 74% was women. The parameters of the HRT II that were better correlated with the glaucoma diagnosis was the height contour variation, the rim area and age with an area under the ROC curve 0.6579 (standard error 0.0561). For the pattern the best cut point went bigger or similar to 0.53 with a sensitivity of 0.6275 and a specificity of 0.6304. When applying discriminative analysis from Mickelberg to the available data we found a ROC curve area of 0.5892 with a sensitivity of 0.6531 and a specificity of 0.4468 with a pi bigger than 0.5. Conclusions: The acting in the diagnosis of glaucoma of the HRT for this model went superior to the one of formulates by Mickelberg. The parameters of the HRT II that were better correlated with the glaucoma diagnosis were the age, the height contour variation and the rim area.
