Reflection of laser radiation from retina quasi-crystal layers: Model investigations

Reflection of laser radiation from quasi-crystal layers by retina (a layer of nervous fibers and photoreceptor disks) in the framework of holographic model of physiological optics was considered. Graphs for two components of back-scattered field, depending upon the laser incidence angle at retina and the angle between incidence plane and optical axis of retina layer nerve fibers were obtained. Cases of dark-adapted and completely decolorized photoreceptor disks were considered. The results obtained may be used in laser methods for diagnostics and treatment of ophthalmologic diseases.
