Nystagmus – A little known, yet surprisingly common environment
Nystagmus is a type of controlled eye movement that affects approximately one in every 2,000 people, as smooth eye movement changes in one direction and flickers in the other (sudden, short) movements. Moves usually from side to side but sometimes the movement can be up or down or even circular. Nystagmus is not painful and does not lead to progressive loss of vision
Types of Nystagmus
There are more than 40 different nystagmus types, but are usually divided into two basic categories:
1. Early life nystagmus is termed early nystagmus or congenital nystagmus often accompanied by birth loss or short-lived loss of vision and this may be the first sign that the child is lost.
2. Nystagmus, which is later developed in life, is known as Acquired Nystagmus.
1. Early nystagmus: Pediatric nystagmus can cause the eyes or the visual pathways leading to the eye from the brain. This type of nystagmus is usually observed for the first time between 6 weeks and 8 weeks and can be associated with albinism, optic nerve problems or retinal problems. It is probably a genetic factor, and in fact, doctors have recently announced a breakthrough in the discovery of gene related to nystagmus, which is a great promise for future treatments.
Many patients have no eyes, brain or other health problems and in these cases the condition is known to be a congenital idiopathic nystagmus (ie nystagmus starts early and the cause is unknown). The nystagmus associated with albinism has a similar feature to idiopathic nystagm but is usually absent after 2 months. Nystagmus is also found in children with Down syndrome
. Acquired nystagmus: Neurological dysfunction, such as head injury, multiple sclerosis, or brain tumors, can later be acquired in life by nystagmus. Nystagmus can be caused by cerebellum, brainstem where the vestibular skull is generated by nerve or further along vestibular pathways.
Nystagmus is related to decreased vision, tiredness or tension in the eyes, fluctuations in the visual acuity, sometimes head nodding, and often the head at an angle and holding the eyes to one side (this slows motion , gives zero and allows better visions). Patients with nystagmus often face other vision problems such as: Astigmatism requiring prescription glasses and strabism. The deterioration of binocular vision is common in the development of early nystagmus, and depth sensation is indirectly impaired in many patients.
The presence of a faint optical disc or the occurrence of progressive visual loss suggests that nystagmus is obtainable and is likely to be a neoplasm affecting the visual system
The following factors increase the chances of nystagmus: nystagmus, albinism , eye disorders, such as degeneration of the optic nerve, severe astigmatism or proximity, diseases of the body such as Menieres's disease, multiple sclerosis, stroke, head injuries, medications such as lithium or seizures, alcohol or drug use and internal ear infections. nystagmus is not cured, but for the first time more and more researchers are working on the condition and genetic research offers a particularly new hope.  Contact Lenses Contact lenses have been shown to help nystagmus patients, probably due to actual contact, which leads to better regulation of the movement of horizontal nystagmus.
Prisms help narrow the eyes, thus reducing nystagmus.
Simple examinations such as visual acuity may be misleading as vision may be reduced if the patient is under stress or is latent nystagmus that causes nystagmus to grow.
Biofeedback, which involves the patient by visual and acoustic effects affect the regulation of eye movements, it has proved useful to some people.
Surgery, especially tetonomy (restoring and restoring the eye's muscles) has been successfully applied in the United States. Botox, Baclofen and recently Mamentine and Gabapentin are medicines that they try.
Nystagmus can affect almost all aspects of life, including how the patient relies on other people, education and work opportunities, and self-image. People who had nystagmus throughout their lives are not practiced by the ever-moving image, as their brains are aligned with the eye movement, but those suffering from acquired nystagmus can not adapt to dizziness and dizziness
. perception is generally reduced significantly, which can cause problems due to balance and perceived confusion.
With the exception of parts of the United States of America, where optical devices are adopted, nystagmus can not get a driving license, which can be a problem in unknown places.
Socially speaking, it is difficult to contact a nystagmus person, . However, there are many who live in a highly successful and fruitful existence, adapting easily to their condition and creating a perfectly normal life.
For nystagmus children, it is important for their teachers and classmates to know that the state is affecting them to avoid problems caused by misunderstandings. For example, children with nystagmus read the extra time needed to read the printed material slowly. This should not be seen as a sign of bad reading. Nursing students or school children need extra time during the studies and exams. Many nystagmus students use the computer as they can place the screens according to their own needs and adjust the brightness, character size, and so on.
