Abstract

Partial optic nerve avulsion (ONA) secondary to finger gouging is an uncommon but devastating injury. A 21-year-old man who had an acute vision loss after accidentally getting poked by himself in his right eye when he fell down during jogging is reported. The patient was diagnosed with partial ONA. Magnetic resonance imaging revealed intact optic nerve. Optical coherence tomography (OCT) revealed deep cavity at the inferior-temporal half of the optic disc. Retinal nerve fiber layer thickness was also thin at the inferior quadrant with circumpapillary OCT scan. Visual field test and electrophysiological tests showed functional abnormality compatible with optic nerve lesion. Diagnostic tools for anatomical and functional evaluation may reveal the course of this injury.

摘要

部分视神经撕脱(ONA)继发于手指戳伤,是一种不常见但破坏性很大的损伤。报告了一名 21 岁男性患者,他在慢跑时摔倒后不小心戳伤右眼,导致急性视力丧失。该患者被诊断为部分 ONA。磁共振成像显示视神经完整。光学相干断层扫描(OCT)显示视盘下颞半部分有深腔。周边 OCT 扫描显示下方象限的视网膜神经纤维层厚度也变薄。视野检查和电生理检查显示与视神经病变相符的功能异常。解剖学和功能评估的诊断工具可能揭示这种损伤的过程。
