Visual function was assessed in 15 eyes of 11 patients who underwent unilateral (seven patients) or bilateral (four patients) optic canal decompression for presumed compressive optic neuropathies. Both immediate and long-term postoperative vision was evaluated in all eyes. Over 90% of the eyes that had undergone nerve decompression had either the same or improved visual acuity and visual field immediately following surgery. In this group of patients there were no deaths and there was only one postoperative complication, a transient dysphasia caused by an epidural hematoma that was evacuated. Long-term follow-up evaluations revealed that most of the eyes retained their immediate postoperative visual function or showed gradual visual improvement with time. The results of this series as well as a review of the available literature indicate that optic canal decompression via craniotomy can be a safe procedure and that it appears to have lasting visual benefit in many patients.
对11例患者的15只眼睛进行了视觉功能评估，这些患者因疑似压迫性视神经病变接受了单侧（7例患者）或双侧（4例患者）视神经管减压术。对所有眼睛的术后即刻和长期视力进行了评估。超过90%接受神经减压的眼睛在手术后即刻视力和视野保持不变或有所改善。在这组患者中没有死亡病例，术后仅出现1例并发症，即由硬膜外血肿导致的短暂性吞咽困难，该血肿已被清除。长期随访评估显示，大多数眼睛保持了术后即刻的视觉功能，或随着时间推移视力逐渐改善。本系列研究结果以及对现有文献的回顾表明，经颅开颅视神经管减压术是一种安全的手术方法，并且似乎对许多患者具有持久的视觉益处。
