Abstract Purpose To compare the final classification of Glaucoma Probability Score (GPS) and analyze RNFL of OCT and to evaluate their capacities to detect precociously the glaucomatous defects Methods Retrospective study, led in the regional center of glaucoma, in CHUR of Lille, including 122 eyes of 71 patients All the eyes included had, to the maximum, a light visual field defects and having profited all of them of a complete ophthalmic examination including vision, measurement of the PIO, standard automated perimetry, optic nerve head analysis was performed by using a confocal scanning laser ophthalmoscopy type Heidelberg retinal tomography (HRT III) and retinal nerve fiber layer (RNFL) by Optical Coherence Tomography (Cirrus OCT) The patients were divided into 3 groups according to the defect of the visual field: ‐ Group 1 : normal visual field ‐ Group 2 : MD between [0, ‐2] decibels ‐ Group 3 : MD between [‐ 2.1, ‐6] decibels The results of analysis RNFL on OCT and analysis GPS on the HRT were compared in each group. Results The discordance is important in group 2. The sensitivity of the two apparatuses increases with the depth of the defect but remains higher with the HRT. Conclusion There is not a difference between the two analyzers from ‐ 2,1 Decibels The GPS appears to be an algorithm more sensitive than analysis RNFL on OCT in detecting preperimetric glaucoma.
