Figure 1.
Monocular 30° threshold perimetry (A, B), binocular Esterman (C)perimetry and European Driving Test Group 1 (EDT1) perimetry (D) of case 15 (a patient with bilateral glaucoma more advanced in the right eye). The case was passed by 16 experts and failed by 9 experts. At least three adjacent missed test points within 20° or at least nine missed test points within 120°×40° defined a failed EDT1 result in the study, and the patient thus passed the EDT1 test. Notice that the test points are differently placed for EDT1 and Esterman; EDT1 has more central test points and the same number of test points in the upper and lower hemisphere, whereas Esterman extends to 80° horizontally. Accordingly, the EDT1 and Esterman findings are not identical. OS, left eye; OD, right eye.
