Introduction:

Oculogyric crisis (OGC) is a distinctive movement disorder characterized by sudden and sustained upward deviation of the eyes, often accompanied by abnormal posturing of the head and neck. This neurologic phenomenon is typically a side effect of certain medications or a symptom of underlying conditions. In this article, we delve into the clinical features, underlying causes, diagnostic approaches, and management of oculogyric crisis.

Clinical Features:

Oculogyric crisis is characterized by the following features:

• Sudden Eye Deviation: The hallmark feature is the abrupt and involuntary upward deviation of the eyes, resulting in a fixed gaze towards the ceiling.
• Head and Neck Posturing: This eye movement is often accompanied by abnormal posturing of the head and neck, which may tilt backward.
• Duration: The crisis can be brief, lasting only a few seconds, or it can be prolonged, persisting for minutes or even hours.

Underlying Causes:

Oculogyric crisis can be triggered by various factors:

• Medications: Certain medications, particularly antipsychotic drugs, antiemetics, and some antidepressants, are known to cause oculogyric crisis as a side effect. These medications can affect the dopaminergic pathways in the brain, leading to the involuntary eye movement.
• Neurological Conditions: OGC can also be a symptom of underlying neurological conditions such as encephalitis, brainstem lesions, or Wilson's disease.

Diagnostic Approach:

Diagnosing oculogyric crisis involves:

• Clinical Observation: The characteristic upward deviation of the eyes and associated head and neck posturing are often sufficient for diagnosis.
• Medical History: Identifying the use of medications known to trigger oculogyric crisis is crucial in determining the cause.
• Neurological Examination: A comprehensive neurological assessment helps rule out underlying neurological conditions.

Management:

The management of oculogyric crisis depends on the underlying cause:

• Medication Adjustment: If the crisis is triggered by a medication, the treating physician may consider discontinuing or adjusting the dosage of the offending drug.
• Supportive Measures: During an oculogyric crisis episode, providing a calm and safe environment for the patient is essential. Reassurance and monitoring are crucial until the episode subsides.
• Treatment of Underlying Conditions: If oculogyric crisis is a symptom of an underlying neurological condition, addressing that condition is the primary focus of treatment.

Conclusion:

Oculogyric crisis is a distinctive movement disorder characterized by the sudden and sustained upward deviation of the eyes, often accompanied by abnormal head and neck posturing. It can be caused by medications or be a symptom of underlying neurological conditions. Timely recognition, accurate diagnosis, and appropriate management are crucial in alleviating the symptoms and addressing any underlying issues.
