Laser interferometric chromoretinometry in clinical use

摘要

The method of so-called laser interferometric chromoretinometry based on the use of laser sources with different colors of light in retinometer is considered. The results of application of this method for determination of retinal visual acuity (RVA) at various diseases of eye and for diagnostics of the earliest age pathological changes of a crystalline lens are discussed. Transformation of scatterers structure in the eye at age pathological changes of a crystalline lens results in essential changes in scattering of light angular spectra. Intensity of the scattered light depends on the wavelength, hence, the decrease of contrast of intererence fringes for different wavelengths is different. The dependence of fringe contrast on the wavelength can be used for in vivo diagnostics of crystalline lens pathology.
