摘　　要：目的:观察眼挫伤所致黄斑损害的频域光学相干断层扫描(Frequency Domain Optical Coherence Tomo-graphy)图像特征。方法:对34眼眼外伤患者进行FD-OCT扫描检查。两组之间的比较采用t检验进行。结果:外伤眼急性期黄斑区OCT图像主要表现为:神经上皮浆液性脱离、色素上皮脱离、视网膜内出血及黄斑区神经上皮层变薄。回复期黄斑区OCT图像主要表现为黄斑区神经上皮层变薄、黄斑区增生膜形成、黄斑裂孔。结论:眼挫伤黄斑损害的OCT图像可以提供黄斑区解剖结构改变的重要信息,有助于对病变进行诊断及全面评估。Objective：To observe the charcteristics of Frequency Domain Optical Coherence Tomography（FD-OCT） in the macular injury caused by ocular contusion.Methods：34 eyes of 34 patients with ocular contusion were imaged with FD-OCT.Patients were diagnosed based on history,examination.Total retinal thickness were defined and measured on FD-OCT images in all subjects and were compared between the two groups using t tests.Results：Serous neuroepithelium detachment,retinal pigment epithelium detachment,inter retinal hemorrhagic and retinal in macular was thinner were found in early.Retinal in macular was thinner,macular hole and proliferative vitreoretinopatthy were found in late.Conclusions：OCT can display the morphological characters of macular injure caused by ocular contusion,and we could acknowledge the disease more completely and directly by OCT.
