ICD-10: H47.293

Optic atrophy refers to the degeneration of the optic nerve, which can lead to a significant loss of vision. The ICD-10-CM code H47.293 specifically designates "Other optic atrophy, bilateral," indicating that the condition affects both eyes and is categorized under a broader classification of optic atrophy.

Clinical Description

Definition

Bilateral optic atrophy is characterized by the loss of optic nerve fibers in both eyes, which can result from various underlying conditions. This degeneration can lead to visual impairment, including reduced visual acuity, color vision deficits, and visual field loss. The term "other" in the code suggests that the optic atrophy does not fall under the more common types, such as hereditary optic neuropathies or those caused by direct trauma.

Etiology

The causes of bilateral optic atrophy can be diverse and may include:

• Neurological Disorders: Conditions such as multiple sclerosis or tumors affecting the optic pathways can lead to optic nerve damage.
• Vascular Issues: Ischemic optic neuropathy, where blood flow to the optic nerve is compromised, can result in atrophy.
• Toxic or Nutritional Deficiencies: Exposure to certain toxins or deficiencies in vitamins (like B12) can contribute to optic nerve degeneration.
• Infections: Certain infections, such as syphilis or viral infections, may also lead to optic atrophy.
• Inherited Conditions: Genetic disorders, including Leber's hereditary optic neuropathy, can cause bilateral optic atrophy.

Symptoms

Patients with bilateral optic atrophy may experience a range of symptoms, including:

• Decreased Visual Acuity: A noticeable decline in the sharpness of vision.
• Visual Field Defects: Loss of peripheral vision or specific areas of the visual field.
• Color Vision Changes: Difficulty distinguishing colors, particularly in the red-green spectrum.
• Pallor of the Optic Nerve: Upon examination, the optic disc may appear pale, indicating nerve fiber loss.

Diagnosis

Diagnosis of bilateral optic atrophy typically involves a comprehensive eye examination, including:

• Visual Acuity Tests: To assess the sharpness of vision.
• Visual Field Testing: To identify any areas of vision loss.
• Fundoscopy: Examination of the optic nerve head to observe for pallor or other abnormalities.
