To report and illustrate the main clinical presentations of posterior herpetic uveitis. Narrative review. The ocular manifestations of posterior herpetic uveitis include different clinical presentations. Herpes simplex and varicella zoster can cause acute retinal necrosis, progressive outer retinal necrosis, and non-necrotizing herpetic retinopathies. Cytomegalovirus has been associated with fulminant retinitis with confluent areas of retinal necrosis and retinal hemorrhages, indolent/granular retinitis, and frosted branch angiitis. These diverse clinical presentations are often associated with specific risk factors and different immunological profiles of the host. Herpetic viruses can cause posterior uveitis, presenting various clinical findings. Specific ocular manifestations and the immunological status of the host can help to differentiate the various herpetic entities before laboratory tests confirm the diagnosis. [ABSTRACT FROM AUTHOR]

Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease and the most common systemic association of uveitis in children. JIA is subdivided into seven clinically more homogeneous subtypes, using the International League of Associations for Rheumatology (ILAR) classification system: systemic arthritis, oligoarthritis, rheumatoid factor (RF)-negative polyarthritis, RF-positive polyarthritis, psoriatic arthritis, enthesitis-related arthritis, and undifferentiated arthritis. Uveitis is very rare in patients with systemic onset JIA and in patients with juvenile-onset rheumatoid arthritis. Patients with early-onset antinuclear antibody (ANA)-positive oligoarticular JIA have the highest risk of developing chronic iridocyclitis. Ocular involvement in enthesitis-related arthritis is characterized by recurrent acute symptomatic iridocyclitis. The diagnosis and differential diagnosis of JIA are based on history, physical examination, and laboratory investigations, including complete blood count, acute-phase reactants, ANA, RF, HLA-B27, and musculoskeletal imaging studies. Recent studies have revealed distinct gene expression profiles that may be useful in the diagnosis, classification, and follow-up of JIA patients. [ABSTRACT FROM AUTHOR]

The term "vitritis" refers to the presence of a cellular infiltration of the vitreous body, usually in the context of an intraocular inflammation, but not exclusively. Intermediate uveitis is the most prominent cause of vitritis, including infectious and auto-immune/auto-inflammatory etiologies. Corticosteroids and immunosuppressive therapies should not be started before ruling out the infectious causes of vitritis, especially in immunosuppressed individuals. Other situations can mimic intermediate uveitis such as amyloidosis and ocular tumors. Primary intraocular lymphoma should always be suspected in case of vitreous infiltrations in individuals aged over 50 years. [ABSTRACT FROM AUTHOR]

Objective: To report the clinical features and treatment outcomes in immunocompetent patients with anterior segment inflammation (ASI) related to human cytomegalovirus (HCMV) depending on their ethnic origin.Material and Methods: Multicenter retrospective study of 38 patients with at least one test, either HCMV-positive PCR or GWc.Results: Features of Posner-Schlossman syndrome were observed in 50% of the eyes, Fuchs heterochromic iridocyclitis in 13% of the eyes, chronic nonspecific anterior uveitis in 21% of the eyes, and corneal endotheliitis in 18% of the eyes. PCR and GWc were positive for HCMV in 50% and 96.2% of the eyes, respectively. Glaucoma was diagnosed in 50% of eyes. Treatment was oral valganciclovir in about half of the patients. Other treatments were intravenous ganciclovir and/or ganciclovir topical ointment and/or intravitreal ganciclovir.Conclusions: No obvious association of specific clinical features with individual ethnicity could be identified. We found a high rate of glaucoma in all ethnic groups. There was a delay in diagnosis and specific treatment of HCMV in most patients. [ABSTRACT FROM AUTHOR]

An international, expert led consensus initiative was set up by the Collaborative Ocular Tuberculosis Study (COTS) group to develop systematic, evidence, and experience-based recommendations for the treatment of ocular TB using a modified Delphi technique process. In the first round of Delphi, the group identified clinical scenarios pertinent to ocular TB based on five clinical phenotypes (anterior uveitis, intermediate uveitis, choroiditis, retinal vasculitis, and panuveitis). Using an interactive online questionnaires, guided by background knowledge from published literature, 486 consensus statements for initiating ATT were generated and deliberated amongst 81 global uveitis experts. The median score of five was considered reaching consensus for initiating ATT. The median score of four was tabled for deliberation through Delphi round 2 in a face-to-face meeting. This report describes the methodology adopted and followed through the consensus process, which help elucidate the guidelines for initiating ATT in patients with choroidal TB. [ABSTRACT FROM AUTHOR]

Cytomegalovirus (CMV) anterior uveitis is the most common ocular manifestation of CMV disease in immunocompetent individuals. It is thought to be due to a local reactivation of latent CMV and is usually unilateral. The acute form presents as Posner-Schlossman Syndrome, a recurrent hypertensive anterior uveitis with few granulomatous keratic precipitates. There are geographic differences in the chronic form of CMV anterior uveitis. Asian patients commonly present as Fuchs Uveitis Syndrome with diffuse stellate keratic precipitates, while the European patients present with a chronic hypertensive anterior uveitis with fewer keratic precipitates that are brown in color and located inferiorly. Characteristic features of CMV anterior uveitis include mild anterior chamber inflammation, elevated intraocular pressure, stromal iris atrophy. Synechiae, macular edema and retinitis are typically absent. CMV disease may also be associated with the development of corneal endotheliitis with a reduced endothelial cell count. Long-term complications include glaucomatous optic neuropathy and cataract formation. [ABSTRACT FROM AUTHOR]
