Abstract

. The use of a short wavelength laser type and a logarithmic correlator improves the signal to noise ratio of photon correlation functions obtained from mammalian eye lenses in vivo to such an extent that shorter measurement times and a low primary intensity laser light are possible without impairing the information content of the correlation function. Experimental correlation functions obtained in vivo on a rabbit eye lens are analysed with several techniques. The histogram approach is most successful for the determination of the distribution function of relaxation processes in the correlation function and proposes four different populations of components in the lens. This result is comparable to that from in vitro measurements on highly concentrated solutions of cx-crystallins and of fiber cell cytoplasm the former proteins being the main scattering components both in vivo and in vitro in the eye lens system.
