Yes. VOG testing is extremely safe. As we are evaluating the function of impaired neurological systems, the tests can be challenging and fatiguing for some individuals. Each test is only a minute or two long, with rest breaks in between when necessary.

Eye movements are generated from the brainstem, but are initiated and controlled by higher centers in the brain. Long, thin pathways run from the higher brain areas to the brainstem. These are sensitive to stretch and shearing forces in concussions and traumatic brain injuries. They can be impaired in neurodegenerative diseases, or damaged by strokes. They show specific patterns of dysfunction in movement disorders, vertigo, headaches, and cognitive disorders. A wide variety of central nervous system disorders can impact the production and control of eye movements. Impaired eye movements can be found in virtually all forms of central neurological disorders, and in many peripheral conditions as well.

VOG testing shows us how well you can use critical types of eye movements to make sense of your world. All of your eye movements are generated by a set of common neurological structures in the brainstem that drive eye muscles. There are several different classes of eye movements, and all of them are controlled by different parts of the brain. The ability to follow a moving target is controlled by an entirely different part of the brain from the ability to quickly jump between targets. The ability to hold eyes still on a target is similarly controlled by yet another part of the brain. Research shows direct links between impairments in eye movements and deficits in other motor, cognitive, and psychiatric functions that arise from these brain regions. Research also shows that rehabilitation of these eye movements can often lead to improvement in these associated functions. 

VOG testing lets us see exactly how well all of these varied regions of the brain are working. Unlike neurodiagnostic imaging techniques such as MRI and CT scans, VOG is a functional test. It not only shows us how well these brain regions are functioning, but also lets us see under what conditions they may fatigue and fail. This gives us an enormous amount of information about what we need to do to get these regions all working well together again. VOG testing is a foundational aspect of every NeuroRescue Program.

Yes. We use advanced therapies and rehabilitation exercises to restore normal eye movement function, so you can find the world quickly and accurately, localize yourself within it, and respond to it effectively. Rehabilitation of eye movements is one of our most effective therapies in resolving neurological dysfunction, so we can get you back to living your best life as fast as possible.
