Nystagmus is a condition of involuntary (or voluntary, in rare cases) eye movement, acquired in infancy or later in life, that may result in reduced or limited vision. Due to the involuntary movement of the eye, it has been called “dancing eyes”.
In a normal condition, while the head rotates about an axis, distant visual images are sustained by rotating eyes in the opposite direction on the respective axis.The semicircular canals in the vestibule of the ear sense angular acceleration. These send signals to the nuclei for eye movement in the brain. From here, a signal is relayed to the extraocular muscles to allow one’s gaze to fixate on one object as the head moves. Nystagmus occurs when the semicircular canals are being stimulated (e.g. by means of the caloric test, or by disease) while the head is not in motion. The direction of ocular movement is related to the semicircular canal that is being stimulated.
Some of the cases of congenital nystagmus may be hereditary. In some cases there is clearly a family background sometimes going back over several generations. In others the disorder appears to be a singular occurence. In cases of ocular albinism and cone dysfunction, it is known that there is a definite hereditary basis. Genetic research is one of the fastest growing areas of medicine in the nineties. It is likely to prove of great importance to those with eye problems such as nystagmus.
Nystagmus affects people in many ways and the effects vary from person to person.
Most people who have had the condition since childhood do not suffer from a constantly moving image (known as ‘oscillopsia’) most of the time, as their brains adapt to the movement of the eyes. However, people who acquire nystagmus in later life are unlikely to adjust so well and will suffer much more from the effects of oscillopsia.
Nystagmus often seriously reduces vision. The degree of sight loss varies from person to person and is also related to the underlying condition. Many sufferers are eligible to be registered as partially sighted or blind. Please note that most people registered blind have poor vision, not no sight at all.
Nystagmus is a condition regarding your vision where your eyes make involuntary repetitive movements. If this condition is left untreated then it can result in impaired vision, and improper balance coordination. Due to this condition you cannot maintain a suitable balance and the ones who are affected with this condition, they often nod their heads in unusual positions to maintain balance. There are 3 types of Nystagmus. The first one is known as Infantile, where it develops in infants within two to three months of birth and the infants often involuntarily swing their heads and it is also associated with other conditions such as albinism, congenital problems etc. Spasmus nutans is another form of Nystagmus where it occurs within 6 months to 3 years of age and gradually improves. In this condition you tilt and nod your head and the eyes move in different directions. This type of Nystagmus does not require any treatment. The other from of Nystagmus is known as Acquired Nystagmus where it can develop in childhood or adulthood where the cause is primarily unknown and they can cause metabolic and central nervous system disorders. The main causes of Nystagmus are due to albinism, inflammation in your ear, side effects of central nervous system diseases and congenital cataracts.
The treatment of this condition starts off with examinations in your eye and to detect the extent to which your vision is affected. The tests are conducted to decide the course of treatment that you need. Contact lenses sometimes improve the vision but they do not cure the condition of Nystagmus. In rare cases, surgery is performed to improve the functioning of the muscles associated with your faulty eye and it reduces your need to tilt your head every now and then. In some cases of this condition, treatment is not required but lenses are prescribed to help you see properly at the things that you couldn’t focus on. Most treatments associated with this condition are aimed at suppressing the abnormal eye movements without hampering the normal eye movements. Till this date, the condition of Nystagmus cannot be completely cured and mostly glasses and lenses are used to eliminate the vision problems that you are facing. The surgery for this kind of treatment procedure reduces the null positions in your eye and reduces your need to tilt your head every now then. Even animals can develop this condition. Dogs that suffer from this condition are caused by ear infections, trauma and hypothyroidism. This can be treated with various medications and vaccines.
If you are facing sensitivity in your eyes when you are exposed in areas of bright light and also feel dizzy at times with difficulty in seeing in the dark, vision problems and even the feeling that everything around you is shaking then call up your medical expert as you might be eligible for this treatment. Often to see properly you need to adjust your head and this sometimes might happen involuntarily. If you are facing these symptoms then you are eligible for this kind of treatment after proper diagnosis of the condition.
