title: [Light scattering by corneal stroma during edema: relation between spectral law and scattering intensity].
abstract: The quantity D of light scattered by a layer is proportional to the n-th power of the wavelength. This has been checked with five rabbit corneas at different stages of hydration and the corresponding values of n have been calculated. It appears that, during the progress of edema, D and n remain connected through the linear relation : n = aD + b. The constants a and b are determined as well as the correlation coefficients. That physical link between n and D throws a light on the nature of ultra-structure alterations occurring in the edematous stroma.
