Abstract

Recently, we presented a new research instrument to perform dynamic light scattering measurements in each section of the eye axis from the cornea to the retina. Using this instrument, a set of in vivo measurements of static scattered light at the scattering angle of 174 degree(s) on different ocular tissues has been performed. From these measurements the Rayleigh ratio has been evaluated. The motivation for the present study is the complete lack, in literature, of this important scattering parameter for ocular tissue. Rayleigh ratio is important to evaluate a- priori the predetection signal achievable by scattering probes from different ocular tissues. In vivo measurements have been performed on thirty normal subjects aged 16 - 73 years, and Rayleigh ratio has been evaluated as a function of the measuring position and subjects age.
