Below is a detailed overview of the clinical presentation, signs, symptoms, and patient characteristics associated with ICD-10 code H20.821, which specifically refers to Vogt-Koyanagi syndrome affecting the right eye.

Clinical Presentation

Ocular Symptoms

The ocular manifestations of Vogt-Koyanagi syndrome are often the most prominent and can include:

• Uveitis: This is the inflammation of the uveal tract, which includes the iris, ciliary body, and choroid. Patients may experience pain, redness, and photophobia (sensitivity to light).
• Choroiditis: Inflammation of the choroid can lead to visual disturbances, including blurred vision or scotomas (blind spots).
• Retinal Detachment: In severe cases, the inflammation can lead to complications such as retinal detachment, which is a medical emergency.

Systemic Symptoms

In addition to ocular symptoms, patients may present with systemic signs, including:

• Tinnitus: Ringing or buzzing in the ears is common due to the involvement of the auditory system.
• Headaches: Patients may experience severe headaches, often associated with neurological symptoms.
• Meningeal Signs: Symptoms such as neck stiffness or photophobia may indicate meningeal irritation.

Neurological Symptoms

Neurological involvement can manifest as:

• Dizziness: Patients may report episodes of vertigo or imbalance.
• Cognitive Changes: Some individuals may experience memory issues or changes in mental status.

Signs and Symptoms

Common Signs

• Visual Acuity Loss: Patients may report a decrease in vision, particularly in the affected eye.
• Fundoscopic Findings: Upon examination, signs of uveitis, such as keratic precipitates, may be observed. There may also be evidence of retinal edema or exudates.
• Pupil Reaction: The affected eye may show a relative afferent pupillary defect (RAPD) if there is significant retinal involvement.

Symptoms

• Photophobia: Increased sensitivity to light is a common complaint.
• Floaters: Patients may notice spots or floaters in their vision due to inflammation.
• Color Vision Changes: Some patients report alterations in color perception.
