PURPOSE
To evaluate changes in the retinal nerve fiber layer following traumatic optic neuropathy.
DESIGN
Observational case report.
METHODS
A patient presented with visual loss after an accident. Scanning laser polarimetry was performed.
RESULTS
Thickness of the retinal nerve fiber layer increased immediately after the trauma but then progressively decreased. Severe loss was observed at day 90 and then ceased. Enlargement of the optic disk cup was also observed.
CONCLUSIONS
This is the first report documenting early transient increase followed by progressive loss of the retinal nerve fiber layer in traumatic optic neuropathy.
目的
评估外伤性视神经病变后视网膜神经纤维层的变化。
设计
观察性病例报告。
方法
一名患者在事故后出现视力丧失。进行了扫描激光偏振仪检查。
结果
创伤后视网膜神经纤维层厚度立即增加，但随后逐渐减少。在第90天时观察到严重变薄，随后停止。还观察到视盘杯扩大。
结论
这是第一份记录外伤性视神经病变中视网膜神经纤维层早期短暂增加随后逐渐丧失的报告。
