Relative afferent pupillary defects (RAPD) may be detected in patients with occipital lobe lesions. However, no previous report has used an objective technique to record the abnormal pupillary light reflex in such cases. Therefore, we measured the pupillary light reflex objectively in 15 patients with homonymous visual field defects (HVFD) due to occipital stroke using a new pupillometer. This study detected significantly smaller and slower pupillary light reflexes in the contralateral eyes than in the other eyes, which is equivalent to the presence of RAPD in patients with HVFDs caused by retrogeniculate lesions using an objective technique. Our results confirmed those of the previous reports using the swinging flashlight test more objectively.
枕叶病变患者可能检测到相对性传入性瞳孔障碍（RAPD）。然而，此前尚无报告使用客观技术记录此类病例中异常的瞳孔光反射。因此，我们使用一种新型瞳孔计，对15例因枕叶卒中导致同向性视野缺损（HVFD）的患者进行了客观的瞳孔光反射测量。本研究检测到，与对侧眼相比，患侧眼的瞳孔光反射明显更小且更慢，这等同于使用客观技术在由膝状体后病变导致的HVFD患者中检测到RAPD。我们的结果比之前使用摆动手电筒试验的报告结果更客观地证实了这一点。
