最近Noell 1,2和我们都证明了暴露在光线下会对视网膜造成严重损害。3,4为了确定视网膜的发病机制，本实验室在不同条件下对视网膜进行了一系列的电子显微镜研究。根据光照射的持续时间和光源的性质，视网膜显示的损伤从整个视网膜的完全退化到光感受器的微小变化都有所不同。暴露在相对较冷的光线下，亮度约为750英尺烛光（ft-c），白化大鼠的感光外节表现出显著的膜性变化。本文的目的是描述这种变化的感光细胞，并讨论损伤的机制。材料与方法以白化大鼠为实验对象。普通金属丝网动物笼
SEVERE damage to the retina by exposure to light has recently been demonstrated by Noell 1,2 and by us. 3,4 To establish the pathogenetic mechanisms, a series of electron microscopic studies of the retinas which had been exposed to lights under several conditions has been in progress in this laboratory. Depending on the duration of the light exposure and the nature of the light sources, the retinas show damage varying all the way from total degeneration of the whole retina to minimal changes in the photoreceptors. Upon exposure to relatively cold light at a brightness of approximately 750 foot-candles (ft-c), photoreceptic outer segments of the albino rat demonstrate remarkable membranous changes. The purpose of this paper is to describe such changes in the photoreceptic cells and to discuss the mechanisms of the damage. Materials and Methods Albino rats were mainly used in the experiment.
