MODELING OF THE AUTOFLUORESCENCE SPECTRA OF THE CRYSTALLINE LENS WITH CATARACT TAKING INTO ACCOUNT LIGHT SCATTERING
Abstract
The model of the autofluorescence spectrum formation of crystalline lens taking into account light scattering was presented. Cross sections of extinction, scattering and absorption were obtained numerically for models of normal crystalline lens and cataract according to the Mie theory for polydisperse systems. To validate the model, data on the autofluorescence spectra of the normal lens and cataracts were obtained using an experimental ophthalmologic spectrofluorimeter with excitation by UV light emitting diodes. In the framework of the model, the influence of the lens light scattering on the shape of the luminescence spectrum was estimated. It was found that the changes in the fluorescence spectrum of lenses with cataracts can be completely interpreted by the light scattering.
