With the improved resolution of the newer B-scan instrumentation, echography can be used to confirm rapidly and accurately the diagnosis of optic disc drusen. Over a 4-year period, we retrospectively identified 48 patients with the echographic diagnosis of optic disc drusen. Ages ranged from 6 to 78 years. Drusen were echographically bilateral in 69% of these patients. In 30 eyes, drusen were not visible clinically but were detected echographically. Standardized A-scan echography also helped to confirm the diagnosis of pseudotumor cerebri (2 patients) and optic neuritis (2 patients), emphasizing the need for performing a thorough evaluation before attributing clinical findings of an ophthalmoscopically abnormal optic nerve head to optic disc drusen. Six of 48 patients had vascular occlusions at the level of the optic nerve head. In 5 of these 6 patients, unilateral deep optic disc drusen were detected on the side of the occlusion. This finding lends support to the theory of potential mechanical compression of vascular structures by optic disc drusen.
随着新型B超检查设备分辨率的提高，超声检查可用于快速、准确地确诊视盘玻璃疣。在4年的时间里，我们回顾性地确定了48例经超声诊断为视盘玻璃疣的患者。年龄范围为6至78岁。这些患者中69%的视盘玻璃疣在超声检查中为双侧性。在30只眼中，视盘玻璃疣在临床上不可见，但在超声检查中被检测到。标准化A超检查也有助于确诊假脑瘤（2例患者）和视神经炎（2例患者），这强调了在将检眼镜检查发现的异常视神经乳头的临床体征归因于视盘玻璃疣之前，需要进行全面评估。48例患者中有6例在视神经乳头水平出现血管阻塞。在这6例患者中的5例中，在阻塞侧检测到单侧深部视盘玻璃疣。这一发现支持了视盘玻璃疣对视神经乳头血管结构可能存在机械压迫的理论。
