Forced Convection Mechanism Failure in the Eye Can Cause Cataract

Although the exact causes for presbyopia are not known with certainty, there is the general understanding that it is associated with aging. This is one of the major paradigms of science because the analysis of the symptoms observed during the treatment of presbyopia in the first author of this paper indicates that presbyopia is associated with metabolic dehydrated secretions that have accumulated in various parts of the eyes. As a process of accumulation it is not difficult to associate it statistically to aging. The metabolic secretions produced by the cells inside the human eye are accumulated simultaneously in the cornea, trabecular meshwork, in the lens and retina, subject only to its origin, however, the symptomatology is well characterized by the location of accumulation. Genetic factors are directly related to how the clumps of metabolic secretions occur and the accumulation form is very specific according to the movement of the eyes based on the activities performed by the patient, so any outcome is unpredictable. In this paper introduces the hypothesis that senile cataract may be caused by transport mechanism failure by forced convection of aqueous humour and metabolic mass produced by the lens cells. The evidence confirms the comparative interpretation of physiology and biochemical constituents of studies between old and young lenses published in scientific literature. Besides that the accumulation produces a loss of elasticity of the lens, due to excess volume and causes its opacity because the metabolic secretion is translucent. It shows evidence of the formation of floaters.
