作者对69例缺血性枕叶梗死患者的完全同向性偏盲恢复情况进行了一项前瞻性研究。用动态视野计所记录的结果采用平面测量技术进行评估。在32例患者（47.8%）中发现有改善，并且对这些患者的改善时程以及视野中改善的部位进行了研究。功能恢复在下象限（46.9%）和颞侧新月区（75%）更为常见。最初的改善最常出现在下象限（37.5%），并且在CT研究中与楔叶的保留有关。在上象限恢复的患者中，71.7%的患者该结构有脑梗死。在后一组患者中，枕颞回受累的频率要低得多（28.6%）。结果表明血管机制在恢复过程中起作用。
The authors performed a prospective study of recovery from complete homonymous hemianopia in 69 patients who had suffered ischemic occipital lobe infarction. Findings documented with kinetic perimetry were evaluated with a planimetric technique. Improvement was found in 32 patients (47.8%), and the temporal course of improvement as well as the location of improvement in the visual fields in these patients were investigated.Recovery of function was more common in the lower quadrants (46.9%) and in the temporal crescent (75%). Initial improvement was observed most often in the lower quadrants (37.5%) and was associated with preservation of the cuneus in CT studies. This structure was involved in brain infarction in 71.7% of patients in whom recovery of the upper quadrants was observed. The occipito-temporal gyri were affected much less frequently (28.6%) in the latter group of patients. The results suggest that vascular mechanisms were operant in the recovery process.
