In-vitro human sclera structure analysis using tissue optical immersion effect

Far-zone speckles statistical and correlation properties has been investigated in the case of He- Ne laser light scattering by the human sclera samples. Application of some agents such as Trazograph (or Verographin) leads to the decrease of the tissue turbidity and allows us to study the transition from strong scattering mode to weak scattering mode. Usage of this technique in combination with the spatial speckle correlometry gives the possibility for analysis of the sclera's scattering structure for different stages of its turbidity decay. Potentialities of such a method are discussed.
