Abstract

The retinae of anaesthetised Dutch rabbits were exposed to white light of various intensities * (*67--235 mW/cm2 measured at 2.5 cms from the end plate of the light guide) for a period of one h. After this period the animals were killed and tissue taken for investigation by light and electron microscopy. The higher intensities produced marked disruption of the visual cell outer and inner segments as well as a variety of morphological changes in the pigment epithelium. The highest intensity produced severe disruption of the visual cells and pigment epithelium in addition to a general disruption of the other retinal layers. Accompanying the retinal damage there was an inflammatory response in the choroid of the experimental eyes and surprisingly, at some intensities, a similar inflammatory response in the choroid of the control eye.

摘要

将麻醉后的荷兰兔视网膜暴露于不同强度的白光下(在距离光导末端板2.5厘米处测得的强度为67 - 235毫瓦/平方厘米),持续一小时。在此时间段后,处死动物并取组织进行光学显微镜和电子显微镜检查。较高强度的光导致视觉细胞外段和内段明显破坏,以及色素上皮出现各种形态学变化。最高强度的光除了使其他视网膜层普遍破坏外,还导致视觉细胞和色素上皮严重破坏。伴随视网膜损伤,实验眼脉络膜出现炎症反应,令人惊讶的是,在某些强度下,对照眼脉络膜也出现了类似的炎症反应。
