If you do a retrobulbar block, the nystagmus will stop.
The cerebellum and brainstem are the main areas of the brain involved in regulating nystagmus. The cerebellum helps coordinate eye movements, while the brainstem controls the eye muscles involved in nystagmus. Irregularities in these areas can lead to nystagmus.
There are many causes of nystagmus. Nystagmus may be present at birth. It may be a result of the lack of development of normal binocular fixation early on in life. This can occur if there is a cataract at birth or a problem.
Symptoms of nystagmus include involuntary rhythmic eye movements, difficulty with vision, dizziness, and problems with balance and coordination. These symptoms can vary in intensity and may be exacerbated by stress or fatigue.
Commonly, nystagmus is defined as rapid, repeated movements of the eyes. Clinically, physiological nystagmus is a type of eye movement characterized by alternating slow phase movements in one direction and Saccade-like quick phases in the other direction.
The nystagmus test has to do with checking eye movement, which is not voluntary. This movement may result in limited vision. One nystagmus test, caloric reflex test is by filling up one of the ear canals with water or air. The movement of the eyes is then recorded.
The suffix in "degenerative" is "-ive".
The symptom you describe sounds as though it might be "nystagmus." WIKIPEDIA has an article on that symptom: http://en.wikipedia.org/wiki/Nystagmus
Those with nystagmus may have trouble seeing the graphics in 3D. In such cases, it would be best to turn the 3D effect off.
Nystagmus can be caused by various nerves, but the vestibular nerve is often involved. The vestibular nerve carries sensory information related to balance and spatial orientation from the inner ear to the brain. When there is a disturbance in this nerve's function, it can result in nystagmus, which is characterized by involuntary eye movements.
"degenerative arthritis" and "osteoarthritis"
The slow movement of the eye after observing nystagmus helps to reset and stabilize the eyes back to their normal position. These slow movements, called saccades, help to bring the eyes back to the target and maintain focus after the rapid eye movements in nystagmus.
