Diagnostic coincidence of the technologies of analysis of image HRT, OCT and GDx-VCC

Purpose: To value the diagnostic coincidence and specificity between different structural parameters of the topography papilar realized with the HRT3, the optic coherence tomography Stratus OCT 3000 and the laser polarimetry GDx-VCC. Methods: There were included 41 eyes of 41 normal subjects ( intraocular pressure 95 % and a Glaucoma Probability Score - GPS -> 0.51 to level of the HRT, a NFI> 30 in the GDx and an average thickness or in a quadrant of the cap of retinal nerve fiver layer thickness with a value of p <5 % by OCT. Results: The specificities of MRA and GPS were 85 % and 80 %, in the GDx-VCC of 78 % and in the OCT of 71 %. Between the suspects they found 113 positive cases by means of MRA, 153 by GPS, 101 by OCT and 64 by GDx-VCC. Conclusions: It is necessary to possess the analyzers of image in the screening of the glaucoma since they contribute a high specificity, being major the contributed one for the HRT. The opposing specificity is not associated with a low number of positive cases and the diagnostic coincidence of the different analyzers is high. Key words: glaucoma, diagnosis, HRT, OCT, GDx-VCC.
