A new model of the reflection of the human ocular fundus on the basis of the adding-doubling method, an approximate solution of the radiative transport equation, is described. This model enables the calculation of the concentration of xanthophyll in the retina, of melanin in the retinal pigment epithelium and in the choroid, and of hemoglobin in the choroid from fundus reflectance spectra. The concentration values found in 12 healthy subjects are in excellent agreement with literature data. In single cases of pathologic fundus alterations possible benefits to the ophthalmologic diagnostics is demonstrated.
本文描述了一种基于相加-倍增法(辐射传输方程的近似解)的人眼眼底反射新模型。该模型能够根据眼底反射光谱计算视网膜中叶黄素、视网膜色素上皮和脉络膜中黑色素以及脉络膜中血红蛋白的浓度。在12名健康受试者中得到的浓度值与文献数据高度吻合。在个别病理性眼底病变病例中,证明了该模型对眼科诊断可能具有的益处。
