To describe the characteristics of optic nerve head drusen in optical coherence tomography (OCT) images.
Cross-sectional images of the optic nerve were obtained in seven patients with optic nerve head drusen with Stratus and spectral-domain OCT (Carl Zeiss Meditec, Dublin, CA). These were compared to optic disc photographs, autofluorescence, and echography images. For comparison, these tests were performed on four patients with papilledema and three patients with small optic discs.
Optic nerve head drusen typically elevated the disc surface and appeared as an optically empty cavity, sometimes with a perceptible reflection from the posterior surface. The disc surface was also elevated in cases of papilledema, but had a strong anterior reflectance behind which there was no visible structure. The surface of the small optic nerves was slightly elevated, but with less anterior reflectance.
Optic nerves with drusen showed features in these OCT images that were distinct from cases of papilledema or small optic discs.
描述光学相干断层扫描（OCT）图像中视乳头玻璃疣的特征。
使用Stratus和光谱域OCT（卡尔·蔡司医疗技术公司，加利福尼亚州都柏林）获取7例视乳头玻璃疣患者的视神经横断面图像。将这些图像与视盘照片、自发荧光图像和超声图像进行比较。作为对照，对4例视乳头水肿患者和3例小视盘患者进行了这些检查。
视乳头玻璃疣通常使视盘表面隆起，表现为一个光学上的空洞，有时后表面有可察觉的反射。视乳头水肿病例中视盘表面也会隆起，但前表面反射强烈，其后方无可见结构。小视盘的表面略有隆起，但前表面反射较少。
这些OCT图像显示，有玻璃疣的视神经具有与视乳头水肿或小视盘病例不同的特征。
