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.
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.
Nystagmus can be classified depending upon the type of motion of the eyes. In pendular nystagmus the speed of motion of the eyes is the same in both directions. In jerk nystagmus there is a slow and fast phase.
Myopia itself does not directly cause nystagmus, which is an involuntary eye movement. However, severe or prolonged myopia can be associated with other conditions that might lead to nystagmus. Additionally, individuals with high myopia may experience changes in eye structure that could contribute to visual disturbances, including nystagmus. It's important to consult an eye care professional for a comprehensive evaluation if nystagmus is present.
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 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.
Yes, fatigue can contribute to the development of nystagmus, which is an involuntary eye movement. When a person is fatigued, their neurological and muscular systems may not function optimally, leading to issues with eye control and coordination. Additionally, certain types of fatigue, such as that from prolonged visual tasks, can exacerbate or trigger nystagmus in susceptible individuals. However, it's essential to consult a healthcare professional for a comprehensive evaluation if nystagmus occurs.
