while traditional ophthalmology aims to slow down or even prevent the aggravation of the problem (cell death), the new holistic, clinical approach of vision therapy is to strengthen residual vision, by improving eye, brain, and blood flow.
This “eye–brain–vascular” (EBV) triad ensures that all the processes required for good vision work together well and in a balanced manner.
As Table 1 summarizes, there are many interactions among these three elements and visual problems can arise, if any one of them is disturbed. But the good news is that these mechanisms can be used to improve low vision.
In our holistic vision therapy, we therefore pursue various scientifically sound approaches with the goal to strengthen residual vision:
- Reactivation of “silent cells” and neural transmission from the eyes to the brain,
- Optimization of impulse processing in the visual structures in the brain
- Influencing other functions that either directly or indirectly affect visual processing (e.g., attention, eye movements, cognitive processing, and lowering stress).
The goal to optimize residual vision can be achieved in two ways: (i) by improving blood circulation and (ii) by enhancing synaptic transmission between neurons in the eye and brain.
The Eye–brain–vascular triad shows how closely the eye, brain, and cardiovascular system work together to foster good vision. The eye should not be considered in isolation, but must be considered in the context of the brain and vascularity in order to maximize the reactivation of residual vision.
