The 4-m confrontation visual field test has been successfully used at the Mayo Clinic for many years in addition to the standard 0.5-m confrontation visual field test. The 4-m confrontation visual field test is a test of macular function and can identify small central or paracentral scotomas that the examiner may not find when the patient is tested only at 0.5 m. Also, macular sparing in homonymous hemianopias and quadrantanopias may be identified with the 4-m confrontation visual field test. We recommend use of this confrontation visual field test, in addition to the standard 0.5-m confrontation visual field test, on appropriately selected patients to obtain the most information possible by confrontation visual field tests.
除了标准的0.5米面对面视野检查外，4米面对面视野检查在梅奥诊所已经成功应用多年。4米面对面视野检查是一种黄斑功能检查，能够识别小的中心或旁中心暗点，而这些暗点在仅对患者进行0.5米检查时，检查者可能无法发现。此外，通过4米面对面视野检查还可以识别同向性偏盲和象限盲中的黄斑回避现象。我们建议，除了标准的0.5米面对面视野检查外，还应对适当选择的患者使用这种面对面视野检查，以便通过面对面视野检查获得尽可能多的信息。
