Opsoclonus is a rare condition that causes rapid and involuntary eye movements, often associated with neurological disorders, encephalitis, and cancer. Treatment involves identifying and treating underlying conditions, such as chemotherapy or anticonvulsant drugs. Symptoms include sudden eye twitches, which can lead to headaches, dizziness, and nausea. Diagnosis involves brain scans, MRI tests, and blood and urine tests. Treatment varies depending on the underlying cause and may include antiviral drugs, corticosteroids, anticonvulsants, hormone therapy, chemotherapy, radiation therapy, or surgery.
Opsoclonus is a rare medical condition that causes the eyes to move rapidly and involuntarily. The disorder can severely impair normal vision and, in some cases, make it impossible to focus for more than a few seconds at a time. Opsoclonus usually occurs in conjunction with one of many different neurological disorders, encephalitis, and some cancers. Treatment for the condition typically involves identifying and treating other underlying conditions, such as chemotherapy for tumors or anticonvulsant drugs to relieve tremors and muscle spasms.
The most common cause of opsoclonus in infants and children under the age of ten is encephalitis, a serious bacterial or viral infection that causes inflammation in the brain. In older people, opsoclonus is usually a side effect of cancerous tumors in the lungs, genitals, breasts, or brain. A neurological disorder known as opsoclonus myoclonus syndrome can occur in people of any age and causes random, rapid muscle movements in many parts of the body, including the eyes. People who suffer from Parkinson’s disease or epilepsy may also develop symptoms of eye twitching.
An individual with opsoclonus is likely to experience sudden, uncontrollable eye twitches that can occur several times a day. The eyes can twitch sideways or up and down without warning, which can lead to headaches, dizziness, and nausea. Episodes of eye twitches vary in their intensity and in the time it takes for vision to return to normal. The frequency of episodes is also highly variable; some patients enjoy days or weeks without experiencing symptoms, while others constantly struggle with eye problems. Both eyes are equally affected in nearly all patients with the condition.
An individual experiencing symptoms of opsoclonus should be examined by a doctor to determine the exact cause. Neurologists can perform brain scans and MRI tests to check for brain damage and cancerous tumors. Blood and urine tests may be done to check for viral or bacterial infections. Once the cause is identified, doctors can accurately determine the best treatment measures.
Young patients with encephalitis are usually prescribed antiviral drugs or antibiotics, while individuals with opsoclonus myoclonus syndrome are likely to receive corticosteroids, anticonvulsants, and hormone therapy. Other seizure disorders are treated with a number of different anticonvulsants and tranquilizers to minimize the occurrence of eye problems. Cancerous tumors can sometimes be relieved with chemotherapy or radiation therapy, although surgery is often needed to completely remove the cancerous tissue from the brain or other parts of the body.
