目的 观察视网膜中央静脉阻塞（ｃｅｎｔｒａｌｒｅｔｉｎａｌｖｅｉｎ ｏｃｃｌｕｓｉｏｎ，ＣＲＶＯ）所致黄斑损害的光学相干断层扫描（ｏｐｔｉｃａｌｃｏｈｅｒｅｎｃｅ ｔｏｍ ｏｇｒａｐｈｙ，ＯＣＴ）检查的图像特征。 方法 ３８例经间接检眼镜和荧光素眼底血管造影（ｆｕｎｄｕｓｆｌｕｏｒｅｓｃｅｉｎ ａｎｇｉｏｇｒａｐｈｙ，ＦＦＡ）检查确诊的ＣＲＶＯ患者接受了ＯＣＴ检查。所有操作集中在黄斑区，以通过中心凹的等长度和等角度间隔的４ 线扫描为基础，并依据个体情况进行改变扫描线长度、角度及扫描方式的附加扫描。 结果 １５只眼表现为黄斑中心凹囊泡样改变，６ 只眼表现为黄斑区神经上皮脱离，１１ 只眼黄斑区神经上皮不同程度增厚，４ 只眼黄斑中心凹形态大致正常，神经上皮层间有细小液性暗腔，２ 只眼神经上皮显著增厚，层间大量液性腔隙，黄斑前膜组织增生。 结论 ＣＲＶＯ黄斑损害的主要ＯＣＴ图像特征为黄斑囊样水肿、神经上皮脱离以及继发黄斑前膜和色素上皮的改变。了解这些特征性改变有助于对ＣＲＶＯ黄斑损害的诊断和评估。
Objective To observe the image features of optical coherence tomography (OCT) examination of macular damage caused by central retinal vein occlusion (CRVO). Methods 38 patients with CRVO diagnosed by indirect ophthalmoscopy and fundus fluorescein angiography (FFA) underwent OCT. All operations focus on the macular area, based on 4-line scanning of the fovea and equi-angular intervals, with additional scanning of the scan line length, angle, and scan mode to individual conditions. Results In the 15 eyes, macular degeneration was observed. Six eyes showed macular denervation, eleven macular macular neurons were thickened to varying degrees, four macula fovea were normal, and neuroepithelial cortex Between the small liquid dark cavity, 2 eye nerve epithelium was significantly thicker, a large number of layers of liquid cavity, macular anterior membrane hyperplasia. Conclusions The major OCT features of macular lesions in CRVO are cystoid macular edema, neuroepithelial detachment, and secondary macular dementia and pigment epithelium changes. Understanding these characteristic changes can help in the diagnosis and assessment of macular damage in CRVO.
