WHAT IS NYSTAGMUS?
Nystagmus is an uncontrolled, involuntary movement of the eyes. Nystagmus usually affects both eyes and is usually reveals the gaze in a particular direction.
WHAT IS THE CAUSE OF NYSTAGMUS?
Some conditions are associated with nystagmus. Sometimes the brain's control of eye movements is poor, resulting in the inability to look at an object. Some forms of nystagmus are associated with reduced vision, as in albinos, or in cases with scarring of the retina or optic nerve pathologies certain. Rarely nystagmus may occur as the result of brain tumors or severe neurological disorders. Nystagmus can run in families as an isolated problem not associated with other conditions.
WHAT SHOULD BE DONE WHEN YOU HAVE A NYSTAGMUS?
A thorough evaluation by an ophthalmologist and perhaps other specialists such as neurologists will be of great help. There are important data such as age of onset, family history, general health or use of certain medications, which can guide the physician. Your ophthalmologist can examine the type of nystagmus, speed and direction and look for other eye problems such as eyelid ptosis, cataracts or retinal changes or optic nerve, which may be associated.
CAN IT BE CURED NYSTAGMUS?
If we could remove the cause that produced it, we can delete the nystagmus. However, many cases of nystagmus are permanent. Reduced vision can be improved with glasses, low vision aids and special, especially with vision therapy. If the eyes are more stable looking in a particular direction, the raw glasses or surgery eye muscles can improve the position of the head and get a better view.
WHAT ARE THE MOST COMMON FORMS OF NYSTAGMUS?
The Motor Nystagmus starts between 6 weeks and 3 months of age. No member of the family has had a history of involuntary eye movements similar to those presented by the patient. The movement is usually horizontal. Often the convergence or the look in one direction reduces the intensity of nystagmus and improve vision. Fortunately the patients do not see the world around moving as they move their eyes. Visual acuity may be reduced in distance vision, but is usually near normal vision in proximity. Normally there are no limits on the educational potential of a person with motor nystagmus.
The Sensorial Nystagmus, is associated with a decreased vision without any apparent cause. The sensory nystagmus usually begins between 6 and 8 weeks old. The eyes seem to wander, sometimes slowly and sometimes quickly. Often eyes rotate upward. Often the cause of decreased vision is treatable and can reach a situation where the patient can make an almost normal life
ARE THERE OTHER CAUSES OF NYSTAGMUS?
Certain medications or drugs can cause nystagmus. The causes may include: excessive intake of alcohol or the use of medications such as those given for the control of nervous. Nystagmus often improves when stopping the medication that caused it.
Sometimes a person can cause nystagmus, voluntarily, and those who can wiggle his ears. Fine movements may occur, rapid horizontal and can sustain during a short period of time. Often this type of nystagmus is used to attract attention. Some diseases can induce nystagmus, but is less common. It is often associated with neurological signs and symptoms that usually indicate serious problems.
