Purpose: To develop an algorithm for the diagnosis of Behçet's disease (BD) uveitis based on ocular findings. Methods: Following an initial survey among uveitis experts, we collected multi-center retrospective data on 211 patients with BD uveitis and 207 patients with other uveitides, and identified ocular findings with a high diagnostic odds ratio (DOR). Subsequently, we collected multi-center prospective data on 127 patients with BD uveitis and 322 controls and developed a diagnostic algorithm using Classification and Regression Tree (CART) analysis and expert opinion. Results: We identified 10 items with DOR >5. The items that provided the highest accuracy in CART analysis included superficial retinal infiltrate, signs of occlusive retinal vasculitis, and diffuse retinal capillary leakage as well as the absence of granulomatous anterior uveitis or choroiditis in patients with vitritis. Conclusion: This study provides a diagnostic tree for BD uveitis that needs to be validated in future studies. [ABSTRACT FROM AUTHOR]

The article discusses the diagnoses, characteristics, treatment and outcomes of uveitis or eye inflammation, following a mosquito-borne viral infection. Topics include ocular infection by Zika virus, cases of Purtscher-like retinopathy after dengue fever and association of chikungunya virus infection with blurred vision.

Purpose: To describe the epidemiologic, clinical, and histopathologic features of a presumed trematode granulomatous anterior uveitis, primarily in children from south India.Design: Prospective, noncomparative, case series.Methods: Children with clinical evidence of granulomatous anterior uveitis were selected for the study. Those who presented with distinct anterior chamber nodules were evaluated. Demographic details, such as clinical findings and course of illness, were noted. Patients underwent either medical treatment or surgical aspiration of the lesion based on the size of the lesion. Aspirated materials were subjected to histopathologic analysis and cultures for bacteria and fungi. Response to treatment and final visual status were evaluated.Results: One hundred thirteen patients with anterior chamber nodules were seen between 1998 and 2000. Ninety-three (82.4%) were males and 20 (17.7%) were females. The median age was 11.0 years. All patients were from south India and all gave a history of bathing or swimming in the local pond or river. All had normal systemic work ups. Of the 113 patients, 110 had anterior chamber nodules and three had both anterior chamber and subconjunctival nodules. Aspirates of the anterior chamber lesions revealed lymphocytes, intact and necrotic neutrophils, and eosinophils admixed with histiocytes. One subconjunctival nodule showed necrotizing granuloma, displaying the tegument of a trematode. Those patients who were followed had good visual recovery after medical or surgical intervention or both.Conclusion: The present study shows a newly recognized granulomatous anterior uveitis caused by a presumed water-borne trematode infection. This infection appears to be a common cause of pediatric granulomatous anterior uveitis in south India. [ABSTRACT FROM AUTHOR]
