摘　　要：目的分析OCT对急性视网膜坏死的诊断价值。方法回顾分析急性视网膜坏死的眼底照相和OCT图像特征，进行分析总结。结果炎症急性期OCT显示黄白色视网膜病变的区域视网膜弥漫性水肿渗出呈高反射信号，其下结构反射信号屏蔽；神经上皮层下液体积存，视网膜各层组织结构紊乱。黄斑区OCT图像表现为弥漫性水肿，神经上皮层厚度增加，可见高反射渗出物。炎症消退期坏死区域视网膜与正常视网膜相比厚度明显减少，色素上皮破坏。结论OCT能提供急性视网膜坏死患者视网膜精细的形态学特征，结合眼底彩照、眼部荧光造影检查对该病能进行较全面而精细的评估。Objective investigate the characteristics of acute retinal necrosis of optical coherence tomography （OCT） and its clinical application.Methods The fundus photograph and OCT of cases diagnosed as acute retinal necrosis were analyzed retrospectively.Results The characteristics of OCT includes： in the acute phase of inflammation OCT showed that highly-reflective signal in the yellow-white retinal lesion region, exudative and edema retinal structure shielding underlying structure.Liquid exists under neurosensory layer and disorganized retinal structure.Diffuse edema macular.In the inflammation subsided period, thickness of retinal necrosis region decreased significantly compared with the normal retinal RPE damage.Conclusions OCT can provide fine morphological features of the retina in patients with acute retinal necrosis.It can be a more comprehensive and detailed assessment of the disease combined with fundus photograph and FFA.
