Nystagmus is an involuntary eye movement that can be benign or indicate an underlying disease. Some types are normal, while others result from disease, trauma, or neurological disorders. Congenital nystagmus is present at birth, while acquired nystagmus is caused by an event later in life. Treatment options include drugs, contact lenses, low vision rehabilitation, and […]
Nystagmus can be congenital or acquired, with causes including eye diseases, neurological disorders, genetic mutations, physical trauma, exposure to toxins, and central nervous system disorders. Genetic mutations have been identified as possible causes of congenital nystagmus, while acquired nystagmus can be caused by trauma, toxins, or central nervous system dysfunction. Medical intervention may be effective […]
Positional nystagmus is a rapid eye movement caused by body or head position, often accompanied by dizziness. It has various classifications, with the most common cause being benign paroxysmal positional vertigo (BPPV) due to tiny debris in the inner ear. Positional alcohol nystagmus (PAN) is not related to any dysfunction and is caused by alcohol […]
Downbeat nystagmus is an abnormal eye movement caused by a lesion in the cerebellum, often due to structural problems such as an Arnold-Chiari malformation or tumors. Other causes include head injuries, medication, and poor diet. Treatment options include medication, glasses with prisms, and surgery. Downbeat nystagmus is an abnormal eye movement pattern characterized by a […]
Pendulum nystagmus is an eye disorder causing involuntary rhythmic eye movements, often acquired due to vision loss or nerve and muscle disorders. Treatment varies depending on the cause, and an ophthalmologist is typically involved in developing a treatment plan. Abnormal eye movements in someone without a history of vision problems may be a sign of […]
The nystagmus test measures involuntary eye movements and is commonly used in investigations for driving under the influence. A police officer may conduct the test during a field sobriety test, along with other standardized tests. If the driver fails the test, they may be arrested. The term “nystagmus” refers to the involuntary movement of the […]
Vestibular nystagmus causes rapid involuntary eye movements due to disruptions in signal pathways between the eyes, inner ear, and brain. It can be peripheral or central and caused by infections, injuries, or diseases. Treatment includes medication and physical therapy. Individuals with vestibular nystagmus experience rapid involuntary eye movements triggered by a disruption in the signal […]
Rotational nystagmus is the involuntary rotation of the eye caused by an abnormality in the brain. It can be congenital or acquired through injury, toxin, or disease. Treatment includes medication and surgery. Rotational nystagmus refers to the involuntary rotation of the eye and is many times known as eye rolling. This problem can be congenital […]
Vertical nystagmus is an involuntary eye movement that can cause impaired vision and dizziness. It can be congenital or acquired, with the latter being more severe and caused by diseases, nervous system disorders, or exposure to toxins. Some treatments, such as drugs and surgery, show promise in managing the condition. Vertical nystagmus is a type […]
