Nystagmus: Causes, Symptoms & Treatments
Nystagmus is a vision condition in which the eyes make repetitive, uncontrolled movements. The condition can be found in roughly 1 out of every 2000 individuals. The uncontrolled movements often result in reduced vision and depth perception and can affect balance and coordination. The Involuntary eye movements occur from side to side, up and down, or in a circular pattern. As a result, both eyes have difficulty in being able to view objects.
When acquired, the Nystagmus is defined by abnormalities of vestibular input that result in periodic rhythmic ocular oscillation of the eyes. Acquired Nystagmus is caused by disease such as multiple sclerosis or by the neurologic function being compromised by a brain tumor or head injury.
Pediatric nystagmus is caused due to the problem in the eyes of infants that that lead to a disruption in the virtual pathways from the brain to the eyes. Nystagmus that develops in infancy is usually from one of three causes. The most common is simple “congenital nystagmus”, meaning completely normal eyes that jiggle.
Risk factors of Nystagmus
There are some risk factors that are associated with nystagmus. The negative effects of nystagmus are decreased vision and when present it increases the chance of certain problems like severe astigmatism, albinism, optic nerve degeneration.
TreatmentContact lens helps to some extent in reducing this problem. While there is no known cure, it is important to make sure to take the right steps that would help to find the best treatment for nystagmus.
The only proven therapy that can improve vision in case of Nystagmus is RevitalVision, a clinical study on 28 patients from 16 clinics in 5 countries, demonstrated significant improvement in visual acuity as well as contrast sensitivity.
