Consensus guidelines were developed based on published literature, expert opinion, and practical experience to bridge the gap between clinical needs and medical evidence to support the treatment of patients with noninfectious uveitis with noncorticosteroid immunomodulatory agents.
Purpose-To determine the frequency of occurrence of limited clinical features which distinguish patients with Vogt-Koyanagi-Harada (VKH) disease from those with non-VKH uveitis. Design-Comparative case series. Participants-1147 total patients.Methods-All patients with bilateral ocular inflammatory disease presenting to any of ten uveitis centers in the three month period between 2006-January-01 and 2006-March-31 (inclusive) were asked to participate. The clinical and historical features of disease were obtained from the participants via direct interview and chart review. Patients were stratified based on whether they were diagnosed with VKH disease or non-VKH uveitis for statistical analysis. Main Outcome Measures-Presence or absence of various clinical features in the two populations.Results-Of 1147 patients, 180 were diagnosed with VKH disease and 967 with non-VKH uveitis. Hispanics and Asians were more likely to be diagnosed with VKH than non-VKH disease compared Publisher's Disclaimer: This is a PDF file of an unedited manuscript that has been accepted for publication.

Conclusions-Numerous clinical findings have been described in the past as important in the diagnosis of VKH. The current study reveals that of these, two are highly specific to this entity in an ethnically and geographically diverse group of patients with non-traumatic bilateral uveitis. These clinical findings are 1. exudative retinal detachment during acute disease and 2. sunset glow fundus during the chronic phase of the disease.Vogt-Koyanagi-Harada disease (VKH) is a visually disabling bilateral intraocular inflammation usually associated with extraocular manifestations such as meningismus, vitiligo, poliosis, and dysacusis. 1-3 The extraocular manifestations typically appear in different phases of the disease and may vary in different ethnic groups.1 , 4 -6 For example, cutaneous manifestations are typically absent during the acute phase and appear later in the disease course, while the neurologic and auditory manifestations generally precede ocular manifestations. The absence of concurrent extraocular manifestations may have significant implications for both clinical practice and the conduct of clinical studies, as follows. In the area of clinical practice, variation in manifestations and their timing may cause a delay in establishing the correct diagnosis and thus a delay in the initiation of appropriate treatment. This may result in the disease entering the chronic/recurrent phase and in the subsequent development of complications such as glaucoma, ...
In any patient with uveitis, an infectious cause should be ruled out first. The differential diagnosis includes multiple well-known diseases including herpes, syphilis, toxoplasmosis, tuberculosis, bartonellosis, Lyme disease, and others. However, clinician should be aware of emerging infectious agents as potential causes of systemic illness and also intraocular inflammation. Air travel, immigration, and globalization of business have overturned traditional pattern of geographic distribution of infectious diseases, and therefore one should work locally but think globally. This review recapitulates the systemic and ocular manifestations of several emergent infectious diseases relevant to the ophthalmologist including Rickettsioses, West Nile virus infection, Rift valley fever, Dengue fever, and Chikungunya. Retinitis, chorioretinitis, retinal vasculitis, and optic nerve involvement have been associated with these emergent infectious diseases. The diagnosis of any of these infections is usually based on pattern of uveitis, systemic symptoms and signs, and specific epidemiological data and confirmed by detection of specific antibody in serum. A systematic ocular examination, showing fairly typical fundus findings, may help establish an early clinical diagnosis, which allows prompt, appropriate management.
