To establish the method of vitreous videography using the scanning laser ophthalmoscope, we observed the vitreous in patients with age- or disease-related vitreous changes. We compared the results using four laser wavelengths. The detailed structures of the posterior vitreous cortex, a premacular defect, and a prepapillary glial ring were clearly shown under direct laser illumination. A short wavelength laser was found to be superior to a long wavelength laser for observing the posterior vitreous cortex. Vitreous opacities were clearly shown as dark spots under retroillumination using any of the four laser wavelengths. In vivo visualization of the vitreous was achieved using this new technique, which is superior to conventional biomicroscopy because of its monochromatic laser delivery system and confocal light detection capacity.
为建立使用扫描激光检眼镜进行玻璃体摄像的方法，我们观察了患有年龄相关性或疾病相关性玻璃体改变的患者的玻璃体。我们比较了使用四种激光波长的结果。在直接激光照明下，后玻璃体皮质、黄斑前缺损和视乳头前胶质环的详细结构清晰可见。发现短波长激光在观察后玻璃体皮质方面优于长波长激光。使用四种激光波长中的任何一种进行后照法时，玻璃体混浊均清晰显示为暗点。使用这项新技术实现了玻璃体的体内可视化，由于其单色激光传输系统和共焦光检测能力，该技术优于传统生物显微镜检查。
