Nystagmus

People with nystagmus can’t control their eye movements. Their eyes move rapidly and uncontrollably in an up and down, side to side or circular motion. Nystagmus may be passed down from your parents, or it may be caused by another health issue. The condition can be managed with glasses or contact lenses or rarely, surgery. Overview Nystagmus symptoms like dizziness require a call to your provider. What is nystagmus? Nystagmus (ni- stag-muhs) is a condition in which your eyes make rapid, repetitive, uncontrolled movements — such as up and down (vertical nystagmus), side to side (horizontal nystagmus) or in a circle (rotary nystagmus). These eye movements can cause problems with your Who does nystagmus affect? Nystagmus can affect both children and adults. There are two types: congenital and acquired. Congenital nystagmus Babies with this condition start to show symptoms between six weeks and three months of age. This type of nystagmus is congenital, meaning people are born with it. In some cases, it’s passed down to children from their parents, but the exact cause isn’t always clear. Children with congenital nystagmus usually have it in both eyes. The main symptom is blurry vision. Acquired nystagmus Unlike congenital nystagmus, acquired nystagmus develops later in life. The condition is usually caused by an underlying health condition or drugs. Adults with acquired nystagmus describe their vision as “shaky.” How common is nystagmus? Approximately 1 in 1,000 people have som...

You may feel like your What Causes Nystagmus? It may be a sign of another eye problem or medical condition. You may be born with it, or you might develop it later in life. Nystagmus is caused by many different things, including: • Being passed down from your parents • Other eye issues, like • Diseases like • • • Inner ear problems • Certain • Alcohol or drug use Sometimes, your doctor may not know what causes it. What Are the Symptoms of Nystagmus? Your eyes move without your control. It might be fast, then slow, then fast again. The movement might be in one eye, but it's usually in both eyes. You may notice that you nod your head or keep it in strange positions. You do that because it helps you focus when you can't hold your gaze steady. Things look clearer when you tilt or turn your head. Objects may seem a little blurry to children with nystagmus. But the world doesn't look shaky to them. It's different if you develop the condition as an adult. Then the world appears to move a little when you look around. Nystagmus may also affect your Getting a Diagnosis If you think you or your child may have symptoms of nystagmus, see your eye doctor. They’ll look at the insides of your eyes and test your You might get other tests, including: • Ear exam • Neurological exam • • • Recording your eye movement Your doctor may ask you to spin around in the chair for about 30 seconds, stop, and then try to stare at an object. If you have nystagmus, your eyes will first move slowly in one d...

We do the research so you can find trusted products for your health and wellness. The symptoms include fast, uncontrollable eye movements. The direction of movement determines the type of nystagmus: • Horizontal nystagmus involves side-to-side eye movements. • Vertical nystagmus involves up-and-down eye movements. • Rotary, or torsional, nystagmus involves circular movements. These movements may occur in one or both eyes depending on the cause. Nystagmus occurs when the part of the brain or inner ear that regulates eye movement and positioning doesn’t function correctly. The labyrinth is the outer wall of the inner ear that helps you sense movement and position. It also helps control eye movements. The condition can be either genetic or acquired. Infantile nystagmus syndrome Congenital nystagmus is called infantile nystagmus syndrome (INS). It may be an inherited genetic condition. INS typically appears within the first six weeks to three months of a child’s life. This type of ny...

Nystagmus is a disorder that causes involuntary, rhythmic eye movements. Most forms of nystagmus disorder are caused by an underlying condition. The repetitive movements can make it impossible for someone to keep their eyes fixed and focused on any given object. Eye movements due to nystagmus (“nuh-STAG-muhs”) can resemble someone trying to focus on nearby objects from a fast-moving train window. Other forms can cause much smaller eye movements. Certain forms of nystagmus only develop in Causes Many different things can Certain stimuli or actions can induce nystagmus when someone is exposed to them. Triggers can include: • Hyperventilation • Nicotine • • Flashing lights in front of one eye • Vibrations (in rare cases) • Nystagmus is relatively rare. Between two and three out of every 1,000 people have some form of nystagmus, according to a study published by the journal Most forms of the disorder have a neurological cause, but some are related to the inner ear. They can be classified as one of the following two • Pendular nystagmus (optokinetic)— usually caused by an underlying condition in the eyes or nervous system. • Jerk nystagmus (vestibular)— related to the vestibular system in the inner ear or brain. This is the less common form. Among these two types, nystagmus can be further categorized by one of the following classifications: • Congenital (infantile) nystagmus is present from birth. The condition is visible either directly after birth or within the first 6 months...

shaun / E+ / Getty Images Symptoms Nystagmus typically affects both eyes, but rarely it can affect just one eye. The jerking movements are not usually present all the time, and nystagmus is often more noticeable when you are looking to one side or the other. In severe cases, eye jerking can be present all the time, even when you are looking straight ahead (not to the side). Associated Symptoms If your nystagmus is caused by a neurological condition, you may also experience other effects. The associated symptoms are not necessarily caused by nystagmus and they do not cause nystagmus. Instead, they are usually caused by the illness that triggered nystagmus (such as a brain tumor). If you have any signs of nystagmus, you need to get medical attention. The neurological issues that are commonly associated with eye jerking can progressively worsen if they are not treated. Causes Nystagmus is a symptom of some neurological illnesses and conditions that involve the inner ear. There are many neurological diseases that can be associated with eye jerking. Some of the conditions that cause nystagmus are serious and life-threatening, such as a braintumor. Others are not associated with serious health risks, such as a Labyrinthitis: Inflammation of the inner ear is described as labyrinthitis. It can occur due to an infection or inflammatory disease, or it may be idiopathic (without an identifiable cause). This condition can cause profound dizziness, nausea, and vomiting, and your eye ex...

These movements often result in reduced vision and depth perception and can affect balance and coordination. These involuntary eye movements can occur from side to side, up and down, or in a circular pattern. As a result, both eyes are unable to steadily view objects. People with nystagmus might nod and hold their heads in unusual positions to compensate for the condition. Generally, nystagmus is a symptom of another eye or medical problem. Fatigue and stress can make nystagmus worse. However, the exact cause is often unknown. The forms of nystagmus include: • Infantile. Most often develops by 2 to 3 months of age. The eyes tend to move in a horizontal swinging fashion. It is often associated with other conditions, such as albinism, congenital absence of the iris (the colored part of the eye), underdeveloped optic nerves and congenital cataract. • Spasmus nutans.It usually occurs between 6 months and 3 years of age and improves on its own between 2 and 8 years of age. Children with this form of nystagmus often nod and tilt their heads. Their eyes may move in any direction. This type of nystagmus usually does not require treatment. • Acquired. Develops later in childhood or adulthood. The cause is often unknown, but it may be due to the central nervous system and metabolic disorders or alcohol and drug toxicity. Causes & risk factors Nystagmus is most commonly caused by a neurological problem that is present at birth or develops in early childhood. Acquired nystagmus, which...
