The authors present enhanced depth imaging optical coherence tomography (EDI OCT) and fundus autofluorescence (FAF) characteristics of a patient with bilateral choroidal osteoma and try to make a correlation between two imaging techniques. Two eyes of a patient with choroidal osteoma underwent complete ophthalmic examination. Enhanced depth imaging optical coherence tomography revealed a cage-like pattern, which corresponded to the calcified region of the tumor. Fundus autofluorescence imaging of the same area showed slight hyperautofluorescence. Three different reflectivity patterns in the decalcified area were defined. In the areas of subretinal fluid, outer segment elongations similar to central serous chorioretinopathy were observed. Hyperautofluorescent spots were evident in fundus autofluorescence in the same area. Calcified and decalcified portions of choroidal osteoma as well as the atrophy of choriocapillaris demonstrated different patterns with enhanced depth imaging and fundus autofluorescence imaging. Both techniques were found to be beneficial in the diagnosis and follow-up of choroidal osteoma.
作者介绍了一名双侧脉络膜骨瘤患者的增强深度成像光学相干断层扫描（EDI OCT）和眼底自发荧光（FAF）特征，并试图建立两种成像技术之间的相关性。一名患有脉络膜骨瘤的患者的双眼接受了全面的眼科检查。增强深度成像光学相干断层扫描显示出一种笼状模式，与肿瘤的钙化区域相对应。同一区域的眼底自发荧光成像显示轻度高自发荧光。在脱钙区域定义了三种不同的反射率模式。在视网膜下液区域，观察到类似于中心性浆液性脉络膜视网膜病变的外段伸长。同一区域的眼底自发荧光中可见高自发荧光斑点。脉络膜骨瘤的钙化和脱钙部分以及脉络膜毛细血管萎缩在增强深度成像和眼底自发荧光成像中表现出不同的模式。发现这两种技术在脉络膜骨瘤的诊断和随访中均有益处。
