When testing the visual field by confrontation, the blind spot is too small to be picked up. However, there are other tools of\ഠassessing the visual field that reveal the location of the blind spot. \爀屲The blind spot is located 12° - 15° temporally from 對fixation \⠀挀攀渀琀爀愀氀 瘀椀猀椀漀渀尩 and 1.5° below the . Visual field testing methods are not interchangeable. Confrontation testing elicits 40–90% of VFD identified by SAP—depending on the type of VFD and confrontation testing methods used [5, 6].Since SAP tests the central 24° or 30° visual field from fixation, VFD located outside the central 24° or 30° field are not visualized [8, . The test is based on the assumption that many defects begin in the peripheral field and progress centrally. Kinetic boundary testing can be combined with a traditional confrontation test (McClure, 1988), in which kinetic boundary testing is used to assess the peripheral isopter and confrontation testing is used to assess the central field.Techniques used to perform this test include the confrontation visual field examination (Donders' test). The examiner will ask the patient to cover one eye and stare at the examiner. Ideally, when the patient covers their right eye, the examiner covers their left eye and vice versa.
