To investigate the use of dynamic widefield scanning laser ophthalmoscopy (SLO) and B-scan ultrasonography in imaging vitreous abnormalities in patients with complaints of floaters.
Twenty-one patients underwent both dynamic SLO and B-scan ultrasonography to image their vitreous abnormalities. After reviewing these videos, patients graded each imaging technique on a scale of 1 to 10, based on how closely it represented their visual perception of floaters.
The mean age of the patients (12 women and nine men) was 47.7 ± 18.5 years. The patients graded a median score of nine for SLO imaging (mean = 8.43) compared with a median score of 5 (mean = 4.95) for ultrasound ( P = 0.001). Widefield SLO imaging demonstrated three-dimensional interconnectivity within the condensations of the formed vitreous that exhibited translational and rotational movements with eye saccades.
Floaters are a common complaint, but it is difficult to know whether imaging findings of the vitreous correlate to what patients perceive. Widefield SLO seems to image vitreous abnormalities related to how patients perceive their own floaters better than B-scan ultrasonography. Despite the term "floaters", the vitreous abnormalities in the videos seemed to be manifestations of a complex three-dimensional degeneration of the vitreous framework.
研究动态广角扫描激光检眼镜（SLO）和B超在有飞蚊症主诉患者的玻璃体异常成像中的应用。
21例患者接受了动态SLO和B超检查以对其玻璃体异常进行成像。在查看这些视频后，患者根据成像技术与他们对飞蚊的视觉感受的接近程度，以1至10分对每种成像技术进行评分。
患者（12名女性和9名男性）的平均年龄为47.7±18.5岁。患者对SLO成像的中位评分为9分（平均=8.43），而超声的中位评分为5分（平均=4.95）（P=0.001）。广角SLO成像显示在形成的玻璃体的浓缩物内存在三维连通性，其随着眼球扫视表现出平移和旋转运动。
飞蚊症是一种常见的主诉，但很难知道玻璃体的成像结果是否与患者的感知相关。广角SLO似乎比B超更能根据患者对自身飞蚊的感知来对玻璃体异常进行成像。尽管有“飞蚊”这个术语，但视频中的玻璃体异常似乎是玻璃体框架复杂三维退变的表现。
