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, ...

Tuberculosis in the TB endemic countries commonly manifests in the eye as tuberculous uveitis. There is a wide spectrum of the clinical manifestations of intraocular tuberculosis (IOTB). For want of any gold standard diagnostic tests or diagnostic criteria, the estimates of IOTB prevalence have varied greatly. None of the previously suggested guidelines for diagnosis of IOTB have been validated. We give definitions of clinical signs and diagnostic tests that have been used in the literature. Based on these, we propose a classification of IOTB comprising "confirmed IOTB," "probable IOTB," and "possible IOTB." This of necessity needs consensus among experts before carrying out studies to validate this classification.
