ICD-10: H20.822

Vogt-Koyanagi syndrome (VKS) is a rare autoimmune condition characterized by a combination of ocular, auditory, and neurological symptoms. The ICD-10-CM code H20.822 specifically refers to Vogt-Koyanagi syndrome affecting the left eye. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description of Vogt-Koyanagi Syndrome

Overview

Vogt-Koyanagi syndrome is primarily an inflammatory disease that affects the melanocytes, which are the cells responsible for pigment production in the body. It is often associated with systemic manifestations, including:

• Ocular Symptoms: These may include bilateral uveitis (inflammation of the uvea), which can lead to vision loss if not treated promptly. Patients may experience symptoms such as blurred vision, photophobia (sensitivity to light), and floaters.
• Auditory Symptoms: Hearing loss is common and can be unilateral or bilateral. Tinnitus (ringing in the ears) may also occur.
• Neurological Symptoms: Patients may present with headaches, meningismus (stiff neck), and in some cases, neurological deficits.

Pathophysiology

The exact cause of Vogt-Koyanagi syndrome is not fully understood, but it is believed to be an autoimmune response triggered by environmental factors in genetically predisposed individuals. The condition is often associated with a history of skin pigmentation disorders, such as vitiligo or poliosis (white patches of hair).

Diagnosis

Diagnosis of VKS typically involves a combination of clinical evaluation and imaging studies. Key diagnostic criteria include:

• History and Symptoms: A thorough patient history and symptom assessment are crucial.
• Ophthalmic Examination: This may reveal signs of uveitis, such as keratic precipitates, anterior chamber cells, and vitreous opacities.
• Imaging: Fluorescein angiography and optical coherence tomography (OCT) can help assess retinal involvement and monitor disease progression.

Treatment

Management of Vogt-Koyanagi syndrome focuses on controlling inflammation and preventing complications. Treatment options may include:

• Corticosteroids: Systemic corticosteroids are often the first line of treatment to reduce inflammation.
• Immunosuppressive Agents: In cases where corticosteroids are insufficient, additional immunosuppressive medications may be used.
• Regular Monitoring: Ongoing ophthalmic evaluations are essential to monitor for potential complications, such as cataracts or glaucoma.
