PURPOSE
To describe two cases of acute traumatic maculopathy using optical coherence tomography (OCT) following high-speed motor vehicle accidents.
DESIGN
Case reports.
METHODS
Patients were examined soon after the accident using Snellen visual acuity (VA), dilated fundus examination, and OCT. Re-examination was conducted two weeks to one month later.
RESULTS
Both patients experienced an immediate reduction in VA of between 20/120 and 20/200. An abnormal yellow foveal reflex was noted at fundus examination in both cases. OCT revealed outer retinal thickening under the fovea and of the neurosensory retina with preservation of the inner retinal architecture and foveal pit. These OCT changes resolved approximately within two weeks of the accidents with near resolution of the visual disturbance in both cases.
CONCLUSIONS
We describe two cases of acute traumatic maculopathy, including its appearance on OCT imaging.
目的
描述两例高速机动车事故后使用光学相干断层扫描（OCT）检查的急性外伤性黄斑病变病例。
设计
病例报告。
方法
事故后不久对患者进行了Snellen视力（VA）、散瞳眼底检查和OCT检查。在两周至一个月后进行了复查。
结果
两名患者的视力均立即下降至20/120至20/200之间。眼底检查发现两例患者的黄斑中心凹反射均异常。OCT显示黄斑中心凹下和神经感觉视网膜外层增厚，内层视网膜结构和黄斑中心凹保存。这些OCT改变在事故后约两周内消退，两例患者的视觉障碍几乎完全消失。
结论
我们描述了两例急性外伤性黄斑病变病例，包括其在OCT成像上的表现。
