OCULAR FLUID FERNING TEST AND FRACTALS

The ferning test can be regarded as a crystallization process obtained by simple water subtraction. Such a process is feasible for every kin d of ocular fluid (i.e. tears and aqueous, vitreous and subretinal flu ids). The ferning test can be described in terms of fractal geometry, as the image characteristics related to this test are consistent with three of the main properties of fractals: self-similarity, fractal dim ension and lacunarity.
