Nystagmus is continuous involuntary rhythmic to and fro movement of the eyes.These movements are horizontal, vertical or circular. Primary purpose of the ocularstudy of these patients is to diagnosis the acquired cases which are caused due to a nervous system disorder and immediately investigations and appropriate actions should be taken care. But in most cases, nystagmus is a congenital problem (either sensory ordynamic).
Sensory nystagmus occurs on an underlying eye disease (a severe loss of vision at birth).Among these diseases are cataract (cataract) congenital glaucoma,Albinism, congenital retinal and the optic nerve disorders. There is no other ocular disorders indynamic nystagmus and these patients have good visualabilities.
Diagnosis and Treatment
The main symptom is rhythmic movements which in most cases can be diagnosed with the naked eye. In some cases there is a compensatory abnormal head posture to be in a situation where there is the least amount of nystagmus. Some patients may suffer from both nystagmus and strabismus, at the same time. In sensory nystagmus, aside from the above symptoms, other underlying ocular symptoms can be diagnosed.
In cases where there is a suspicion of an underlying disease of the nervous system, studies need to be done in this area, and children should be introduced to a neurologist as soon as possible. If nystagmic patientsuffers from any treatable ocular underlying disorder or refractive error, these problems should be solved first. Prism glasses are beneficial in treating nystagmus. Surgical treatment of nystagmus is performed to correct the abnormal position of the head, correct probable refractive errors and decrease the amount ofnystagmus. It is possible with a variety of surgical procedures. It should be noted that none of the above methods can completely eliminate nystagmus.
