“…334-335 capillaries in the model described in [6]. The process of forced convection has mechanical strength resulting from the variation of transient intraocular pressure as described in [3,7,8] and it is the light energy that increases the cellular activity, resulting in an increased mass transfer. The flow in capillaries increases the viscosity continuously as the cells receive nutrients and oxygen and eliminate the metabolic mass with carbon dioxide during its entire course.…”

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. This paper introduces the hypothesis that macular degeneration may be caused by transport mechanism failure by forced convection of nutrients and metabolic mass produced by the retina. The hypothesis examined in this paper considers the symptoms observed during treatment of presbyopia the first author, the analysis of some clinical procedures to diagnose the degeneration, the symptoms described in the publications on this subject as well as showing how some genetic factor may anticipate the disease. It is not hard to make a statistical association of macular degeneration with aging in the hypothesis that it is caused by of metabolic accumulation of secretions produced in the retina.

“…Increased mass transfer resistance across the trabecular meshwork is an important impediment to aqueous humor drainage. Corneal accommodation movement failure hinders its mass transfer movement, thus being the major factor in the metabolic residue storage in the cornea [5]. The cornea stored metabolic residue elimination process consists in the movement of its curvature, in order to recover its healthy accommodation.…”

“…• Amblyopia: The insufficient mechanism of forced convection of the lens prevents the healthy renewal of the moving mass in its interior, so the metabolic residue is agglutinated into particles and kept in suspension. The suspended particles refract, in diffused light, the incident light rays; thus the brain loses control over the ciliary muscle, for lack of clear image [5]. The amblyopic eye can project images through a small slit, because in this way the intraocular light scattering is reduced.…”

“…In [3] it is shown that the prescribed corrective lens are not important for treatment evaluation of the elimination of intraocular metabolic residues. This paper shows how ocular pathologies can physically affect the optic nerve, as it is known that some ocular pathologies are acquired as a result of an accumulation of dehydrated metabolic residues because of a deficiency in the intraocular mass transfer by forced convection [1][2][3][4][5][6][7][8][9][10][11]. The treatment of these pathologies is based on recovery of the intraocular metabolic residue by rehydration and drainage processes.…”

This paper describes several pathologies associated with pathological movements that can cause physical effort on the optic nerve and damage to vision. The accumulation of intraocular metabolic residues increases ocular globe mass and can change its position in the orbit, as well as increase the cornea and crystalline, accommodation resistance, in addition to being able to increase the aqueous humor output resistance. A series of discreet pathologies may result in optic nerve impairment: cyclotorsion and saccadic movement, position in the orbit, and increased intraocular pressure. The cyclotorsion movements can be stimulated by the superior visual field restriction, due to the metabolic residue accumulation in the light transmission regions of this visual field, preventing correct fusion of the images.

“…The analysis was based on the progress of the recovery of the patient's vision, in addition to the conclusions reached in our other publications. The ocular refractive error has its origin in the accumulation, dehydration and agglutination of the intraocular metabolic residue [2] caused by the defect in the mechanical system of mass transfer in the cornea (between the corneal layers) [2][3][4], trabecular meshwork [5], lens [6] and retina [7,8]. Congenital and acquired pathologies increased the mass transfer deficiency.…”

In this chapter, we show the refractive error treatment result of a patient, the first author, who restarted in 2000, after a 4-year break, at the study start. According to previous publications, the treatment consists of rehydration and elimination of agglutinated, dehydrated and deposited metabolic residues in the cornea, the trabecular meshwork, the crystalline lens and the retina, as a consequence of the failure in the mechanism of intraocular mass transfer by forced convection. However, the forced movement of the metabolic mass to rehydrate one region can cause dehydration in another region. Therefore, the patient developed posterior and capsular cataract in their respective eyes, right and left. This dehydration, during the treatment, increases the difficulties for the success of the treatment. The first part is a chronological record of the most important components of the treatment. Then, the research method and the material used are discussed. The main symptoms and signs are analyzed and correlated with the failure of the mass transfer process and the accumulation of metabolic residues. The anatomy of binocular vision is analyzed as a part of the forced convection mechanism, and in conclusion, the report shows the main oculomotor functions, topographic mapping of corneas over an interval of 17 months.
