Abstract

On a basis of a series of a 130 color photographies registered under polarized light, we have studied the respective part of mass reflexions and of diffusions on the formation of fundus images. The results show that the retina is the main centre of mass reflexions which disappear in polarized light. The pigment (hemoglobin, melanin, etc...) become the main factors of the formation of fundus images. We conclude on the risks of errors which can be done by extrapolating the informations given by photography to assess the action of photocoagulation.

摘要

基于在偏振光下记录的一系列130张彩色照片，我们研究了质量反射和散射在眼底图像形成中的各自作用。结果表明，视网膜是质量反射的主要中心，在偏振光下会消失。色素（血红蛋白、黑色素等）成为眼底图像形成的主要因素。我们得出结论，通过外推摄影提供的信息来评估光凝作用可能会产生错误风险。
