Hypotheses and actuating mechanisms of growth of the eyeâ??s optical axis in the metabolic theory of adaptive myopia and in the theory of retinal defocus.
Physiological features of the interconnected functioning of the systems of accommodation, and aqueous humor production and outflow: The regulation systems for accommodation, production and outflow of aqueous humor have one common actuating unit – the ciliary muscle (CM), both in animals and humans. At the same time, the control signals from these systems to the CM can be directly opposite. For example, to open the trabecular pathway of outflow (TPO), it is necessary to reduce the CM. But at the same time, it is necessary to relax the CM in order to see the approaching danger in the distance. So which command will be executed first? In the eye, there is an overriding priority for executing commands from the accommodation system, since the survival of the species as a whole depends on this. The signals of the control system of aqueous production are in the second place by priority, and the signals from the outflow control system are performed last. It is because that the task of maintaining metabolic processes in the eye is more important than the task of removing the spent aqueous humor.Author(s): Dr. Koshits Ivan
