Nystagmus

Nystagmus is a vision condition characterized by repetitive, uncontrolled eye movements. These involuntary eye movements may be side-to-side, up and down, or in a circular pattern, which hinders the eyes’ ability to focus on a steady object. Individuals with nystagmus may hold their heads in unusual positions or nod their heads in an effort to compensate for these vision obstructions. Nystagmus that develops in childhood is typically inherited; if this condition develops later in life, it may be due to an accident injury. In some cases, however, the exact cause for nystagmus is not fully known.

Types of Nystagmus

Forms of nystagmus include congenital nystagmus and acquired nystagmus. Congenital typically develops between two and three months of age. Eyes appear to move in a horizontal swing fashion. Congenital nystagmus is associated with conditions like undeveloped optic nerves, albinism, congenital cataracts, and the congenital absences of the iris.

Acquired nystagmus generally occurs in adulthood. While the cause is typically not know, this condition may be triggered by central nervous system issues due to alcohol or drug toxicity, stroke, multiple sclerosis, or a blow to the head.

Diagnosis and Treatment

A comprehensive eye exam is necessary to diagnose nystagmus. An eye care professional will first study a patient’s history to determine whether environmental factors, general health problems, or medications could be causing any of the symptoms the patient is experiencing. Next, visual acuity measurements will be taken to assess the extent to which vision has been compromised. These tests will help determine the appropriate refractive lens necessary to compensate for nearsightedness, farsightedness, or astigmatism. Finally, tests will be done to determine how the eyes work together to move in unison and focus on a single object.

While there is no “cure” for nystagmus, treatment options are available to help correct other vision problems that may be associated with this condition. Depending on the type of nystagmus, it is also possible that the condition will spontaneously correct itself. In extremely rare cases, surgery may be performed to alter the position of the muscles that move the eye. However, lifestyle changes such as using large-print books, increased lighting, and magnifying devices are generally the preferred treatment methods.

Reviews From Our Satisfied Patients

  • ""Being new to Vermont, I wasn't sure which optometry practice was best for me. I landed at the office of Thomas H. Clark OD after a terrible experience at another optometry office nearby. Dr. Clark and his team have proven to be just what I was looking for. Dr. Clark is an excellent eye doctor and his team provides exemplary service. They offer a good selection of products and their lab turns out excellent high quality lenses that offer the clearest vision correction I have ever had in glasses. Their knowledge, ability, care and professionalism is superior to others that I have found. If you seek vision correction that is spot on, and you value high quality patient care, I recommend a visit to this office in Williston, VT.""
