[The theoretical bases of refractogenesis].

Analysis of results after theoretic and experimental investigations of structural organization of vegetative nervous system, mechanisms of accommodation and its bioregulation allowed to make a conclusion that refractogenesis is formed under the influence of a double reciprocal principle of innervation and regulation (DRP) of effector apparatus of accommodation. According to the author's view, DRP ontogenesis, being genetically determined and characterized by individual character of development, has a decisive influence on the process of refraction formation. The latter is expressed in the fact that in prevailing activity of cholinergic component over adrenergic in their DRP, refraction is orientated towards myopia, and in prevailing activity of adrenergic component over cholinergic, on the contrary, towards hyperopia.
