Not a feature of Vogt Kayanagi Harada Syndrome is
**Core Concept**
Vogt-Koyanagi-Harada (VKH) syndrome is a rare, multisystem autoimmune disorder characterized by inflammation and damage to various parts of the eye, including the uvea. It is often associated with skin and nervous system involvement. VKH syndrome can affect patients of all ages, but it is more common in individuals of Asian or Native American descent.
**Why the Correct Answer is Right**
VKH syndrome typically presents with a combination of symptoms including ocular, skin, and neurological manifestations. The ocular manifestations can include uveitis, vitiligo, and sensorineural hearing loss. However, intellectual disability or abnormalities in cognitive function, as represented by "Norma IQ," are not a characteristic feature of VKH syndrome. The correct answer, "Norma IQ," is incorrect because VKH syndrome does not primarily affect cognitive function.
**Why Each Wrong Option is Incorrect**
**Option A:** Sensorineural hearing loss is a known feature of VKH syndrome, which can result from the autoimmune response affecting the inner ear. This is a characteristic manifestation of the disease.
**Option C:** Vitiligo is a common skin manifestation of VKH syndrome, resulting from the autoimmune destruction of melanocytes. It is a characteristic feature of the disease.
**Option D:** Hyperpigmentation can occur in VKH syndrome due to the deposition of melanin in the affected areas. This can be seen as a result of the autoimmune response.
**Clinical Pearl / High-Yield Fact**
VKH syndrome is a classic example of a multisystem autoimmune disorder that affects the eye, skin, and nervous system. It is essential to recognize the characteristic features of the disease, including uveitis, vitiligo, and sensorineural hearing loss, to make an accurate diagnosis.
