埋藏性视盘玻璃疣OCT检查的临床表现

目的:探讨埋藏性视盘玻璃疣在OCT检查中的特异性表现。方法:回顾性分析经FFA和B超检查确诊为埋藏性视盘玻璃疣6例6眼患者的临床资料,对其OCT检查结果进行分析讨论。结果:患者6例在由视盘玻璃膜疣引起的视盘的高荧光区(造影检查结果),由OCT进行高分辨率成像,在视盘玻璃膜疣处均显示出特异的宽大的条带样的光反射增强的钙质沉积区,这些沉积区能投下阴影,并且之间显示出空隙样的结构。结论:埋藏性视盘玻璃疣在OCT检查时可以见到特异的影像学表现。所以,OCT可以作为诊断埋藏性视盘玻璃膜疣特异性较强的一种辅助检查,可提高埋藏性视盘玻璃膜疣的检出率。

Clinical analysis of buried optic nerve drusen with optical coherence tomography examination

AIM: To explore the specific image of buried optic nerve drusen during optical coherence tomography(OCT)examination.

METHODS: A retrospective study was made on 6 patients with buried optic nerve drusen(6 eyes)diagnosed by fundus fluorescein angiography(FFA)and B scan examination.

RESULTS: The high fluorescence area of optic disc showed on the FFA image of all 6 patients imaged with the spectral OCT revealed cluster of calcium deposits. These deposits demonstrated specific wide bars with high reflectivity casting shadows underneath and had lacunae appearance.

CONCLUSION: Buried optic nerve drusen showed specific image in the spectral OCT examination. Thus, spectral OCT can serve as an assistant examination method with relatively prominent features for diagnosing buried optic nerve drusen. It can help to raise the detection rate of buried optic nerve drusen.
