Positional nystagmus is a medical condition characterized by abnormal eye movements that occur when a person changes their head position or body posture. Nystagmus refers to the involuntary oscillating movements of the eyes, and in positional nystagmus, these movements are triggered by specific changes in head or body position.
When someone with positional nystagmus changes their position, such as bending forward, lying down, or tilting their head, they may experience episodes of rapid, involuntary eye movements. These eye movements can be horizontal, vertical, or even rotary in nature.
Positional nystagmus can be a result of different underlying causes, such as inner ear disorders, neurological conditions, or even medication side effects. It often occurs due to an imbalance in the vestibular system, which is responsible for maintaining balance and spatial orientation.
Symptoms of positional nystagmus may vary among individuals but can include dizziness, vertigo, blurred vision, nausea, and even imbalance. These symptoms typically subside once the head or body is returned to a neutral position.
Diagnosis of positional nystagmus involves a comprehensive evaluation by a healthcare professional, including a detailed medical history, physical examination, and possibly additional tests such as an eye movement study or imaging scans.
Treatment for positional nystagmus depends on the underlying cause and may include medications, physical therapy exercises to improve balance, or specific maneuvers to reposition tiny particles within the inner ear and alleviate symptoms. It is essential to consult with a healthcare professional for an accurate diagnosis and appropriate management of positional nystagmus.
