The authors report on the technique of biomicroscopic vitreous videography using the recently developed charge coupled device (CCD) video camera.
The authors performed biomicroscopic vitreous videography using the CCD video camera connected to a slit-lamp biomicroscope to examine 50 eyes with age- or disease-related vitreous changes in 50 patients. The cases were categorized as follows: 20 normal senile eyes; 10 eyes with retinal breaks; 10 eyes with diabetic retinopathy; 5 eyes with uveitis; and 5 eyes with high myopia. Noncontact positive preset lenses were used for observing the posterior vitreous; a wide-angle funduscopic contact lens and a three-mirror contact lens were used to observe the peripheral vitreoretinal changes.
Using the CCD video camera, dynamic vitreous changes were documented clearly using real-time television monitoring. The video system also allowed rapid review of the vitreous changes.
This new biomicroscopic vitreous videography system will contribute to the study of vitreoretinal diseases and be valuable as an educational tool.
作者报告了使用最近开发的电荷耦合器件（CCD）摄像机进行生物显微镜玻璃体摄像的技术。
作者使用连接到裂隙灯生物显微镜的CCD摄像机对50例患者的50只因年龄或疾病相关玻璃体变化的眼睛进行了生物显微镜玻璃体摄像。病例分类如下：20只正常老年眼；10只视网膜裂孔眼；10只糖尿病视网膜病变眼；5只葡萄膜炎眼；5只高度近视眼。使用非接触式正预置透镜观察玻璃体后部；使用广角眼底接触镜和三面接触镜观察周边玻璃体视网膜变化。
使用CCD摄像机，通过实时电视监测清晰记录了动态玻璃体变化。该视频系统还允许快速回顾玻璃体变化。
这种新的生物显微镜玻璃体摄像系统将有助于玻璃体视网膜疾病的研究，并作为一种教育工具具有价值。
