The purpose of this study was to evaluate the efficacy of three screening tests in detecting glaucoma in its early stage: tendency oriented perimetry (TOP) and frequency doubling perimetry (FDP) visual field tests, and the glaucoma diagnostic (GDx) nerve fiber layer analyzer. Eighteen patients with glaucoma who showed an early defect on HFA c 24-2 and 20 normals underwent the three tests. TOP showed a sensitivity of 94.4% and a specificity of 75%, FDP a sensitivity of 72.2% and a specificity of 100%, and GDx a sensitivity of 77.7% and a specificity of 60%.
