The cases of three patients who developed combined central retinal artery/vein obstruction secondary to retrobulbar anesthesia are presented. In one case the obstruction was presumably present immediately after surgery, while in the other two it was observed to evolve over a period of several days. A dilated optic nerve sheath was demonstrated by contact B-scan ultrasonography in two cases and by computerized tomography in the third case, suggesting intravaginal sheath hemorrhage as a common underlying pathophysiologic process. Partial return of vision was evident in the latter case following orbitotomy with optic nerve sheath decompression.
本文报告了3例因球后麻醉继发视网膜中央动脉/静脉联合阻塞的病例。其中1例阻塞可能在手术后立即出现，而另外2例则在数天内逐渐发展。2例通过接触式B超检查显示视神经鞘扩张，第3例通过计算机断层扫描显示，提示鞘内出血是常见的潜在病理生理过程。在后1例患者中，眼眶切开视神经鞘减压术后视力有部分恢复。
