Nystagmus or repeated sweeping movement of the eye during neurologic evaluation indicates a vestibular problem within the brainstem.
<h3>
What is Nystagmus? </h3>
- A condition of vision where the eyes make repetitive, uncontrolled movements is termed as Nystagmus.
- Reduced vision and depth perception are the results and can affect balance and coordination.
- Both eyes are unable to steadily view objects as the involuntary eye movements occur from up and down, side to side or in a circular pattern.
- A patient with nystagmus might nod and hold their heads in unusual positions to compensate for the condition.
- Fatigue and stress make this condition even worse. The cause of this is unknown.
