眼底的活体光谱反射测量的解释需要眼睛内的辐射传输的精确模型。除了考虑散射和吸收过程外，还必须考虑适当的组织学变化。这种变化导致实验测量的光谱随着眼睛中的位置以及个体之间而变化。在本文中的Monte Carlo模拟的结果。考虑三个组织学变量：RPE黑色素浓度、脉络膜血红蛋白浓度和脉络膜黑色素浓度。通过考虑这三个变量，有可能生成与鼻底的体内实验测量吻合良好的模型光谱。该模型具有一定的影响，从光谱反射率测量提取组织学参数的问题。这些影响进行了讨论，并提出了一种新的方法来解释眼底的图像。
The interpretation of in vivo spectral reflectance measurements of the ocular fundus requires an accurate model of radiation transport within the eye. As well as considering the scattering and absorption processes, it is also necessary to account for appropriate histological variation. This variation results in experimentally measured spectra which vary, both with position in the eye, and between individuals. In this paper the results of a Monte Carlo simulation are presented. Three histological variables are considered: the RPE melanin concentration, the choriodal haemoglobin concentration and the choroidal melanin concentration. By considering these three variables, it is possible to generate model spectra which agree well with in vivo experimental measurements of the nasal fundus. The model has implications for the problem of extracting histological parameters from spectral reflectance measurements. These implications are discussed and a novel approach to interpretation of images of the ocular fundus suggested.
