ICD-10: H52.519

Internal ophthalmoplegia, classified under ICD-10 code H52.519, refers to a condition characterized by the paralysis of the muscles that control eye movement, specifically affecting the internal muscles of the eye. This condition can lead to various visual disturbances and is often associated with other neurological or systemic issues.

Clinical Description

Definition

Internal ophthalmoplegia is defined as a complete paralysis of the internal ocular muscles, which are responsible for controlling pupil size and lens shape. This paralysis can result in difficulties with focusing and may lead to symptoms such as double vision or blurred vision. The term "complete" indicates that the paralysis is total, affecting all functions of the internal muscles.

Affected Eye

The designation "unspecified eye" in the ICD-10 code H52.519 indicates that the condition may not be limited to one eye or that the specific eye affected has not been determined. This can complicate diagnosis and treatment, as the underlying cause may need to be identified to provide appropriate care.

Etiology

Internal ophthalmoplegia can arise from various causes, including:

• Neurological Disorders: Conditions such as multiple sclerosis, myasthenia gravis, or cranial nerve palsies can lead to ophthalmoplegia.
• Trauma: Head injuries may damage the nerves controlling eye movement.
