ICD-10: H55.81

Clinical Description of ICD-10 Code H55.81: Deficient Saccadic Eye Movements

ICD-10 code H55.81 refers to "Deficient saccadic eye movements," a condition characterized by the inability to perform rapid eye movements (saccades) effectively. Saccades are quick, simultaneous movements of both eyes in the same direction, essential for visual scanning and focusing on different objects in the visual field. This condition can significantly impact an individual's ability to read, track moving objects, and engage in daily activities that require visual coordination.

Etiology and Pathophysiology

Deficient saccadic eye movements can arise from various underlying causes, including:

• Neurological Disorders: Conditions such as Parkinson's disease, multiple sclerosis, or stroke can affect the brain regions responsible for controlling eye movements, leading to saccadic deficiencies.
• Developmental Disorders: Some individuals may experience saccadic deficiencies as part of developmental disorders, such as autism spectrum disorder or attention deficit hyperactivity disorder (ADHD).
• Trauma: Head injuries or trauma to the visual pathways can disrupt normal saccadic function.
• Medications: Certain medications, particularly those affecting the central nervous system, may impair saccadic movements.

Clinical Presentation

Patients with deficient saccadic eye movements may exhibit several clinical signs, including:

• Difficulty in Visual Tracking: Patients may struggle to follow moving objects smoothly, leading to visual discomfort or frustration.
