Neurological Optometry is a specialized part of general optometry that deals specifically with the eye-brain connection in ways other than central eyesight clarity. The retina is connected to the body through the brain and as such can influence posture, movement, balance, emotions, cognition, and digestion to name a few. There are pathways from the eye to the brain can be modulated by retinal stimulation.
The fact is that vision dominates all other senses as far as input to the brain is concerned. In addition there are a myriad of connections that feed back into the retina. This multiple lane highway forms the basis of visual perception.
The current model of vision in Behavioral Optometry revolves around several questions that form a sort of heirarchy in visual processing. This platform was proposed by a brilliant optometrist, Dr. Skeffington, over 50 years ago.
The first question is "Where am I?" This is fundamental to vision because the brain and eyes have to judge where you are in space before relating to anything else.There are different parts to this that involve the conscious and the subconscious brain. For example,I am sitting in a chair, my body and brain instinctively know this. My conscious brain knows that I am in an office building in Conifer, Colorado in north America. This pathway of "where am I?" involves connections from the retina to the vestibular(balance) and proprioceptive systems. (the ability to sense the position and location and orientation and movement of the body and its parts) systems.
The second question is "Where is it?" These pathways form the second level of visual processing. Once you know where you are at in space then you can relate to something else and it's location relative to you. These pathways are distinctly different than the ones used for balance, proprioception and central eye sight. These pathways are related to the peripheral retina as opposed to the central retina.
Only when these two questions are answered does central eyesight come in to play. Central eyesight is the third question: What is it? This question forms the basis of traditional eye exams as you look at a Snellen chart. It is important but it is also the slowest pathway from the eye to the brain.
