Purpose: We evaluated laser flare photometry (LFP) values in patients with juvenile idiopathic arthritis (JIA)-associated uveitis.

Methods: Retrospective study. A decrease of the LFP value between baseline visit and 1 month after anti-inflammatory treatment intensification allowed us to define two groups of patients: group 1 (decreased LFP value ≥50%) and group 2 (<50%).

Primary vitreoretinal lymphoma (PVRL) is a high-grade lymphoma affecting the vitreous and/or the retina. The vast majority of cases are histopathologically classified as diffuse large B-cell lymphoma (DLBCL) and considered a subtype of primary central nervous system lymphoma (PCNSL). To obtain more insight into the ontogenetic relationship between PVRL and PCNSL, we adopted an immunogenetic perspective and explored the respective immunoglobulin gene repertoire profiles from 55 PVRL cases and 48 PCNSL cases.

Purpose: To investigate the clinical and virologic-associated and predictive factors of intraocular pressure (IOP) evolution over time and its severity in Fuchs' heterochromic iridocyclitis (FHC).

Methods: Consecutive patients with both clinical FHC and intraocular synthesis of rubella virus (RV)-specific antibodies were included in this study. Specific ocular production of RV antibodies was confirmed using the quotient of serum/aqueous humor ratio of RV IgGs (Crv) and control antiviral IgGs (Cctl), using quantitative serology methods.

Masquerade syndromes represent a large set of ophthalmological entities that mimic inflammatory conditions. Any delay in their diagnosis may be correlated with systemic dissemination or worsening of the causal disease and, therefore, with poor prognosis. One of the disadvantages of the new potent treatments of uveitis is the delay that they can induce in the diagnosis of neoplastic intraocular infiltrations.

Purpose: To investigate clinical and biological factors influencing recurrences of severe toxoplasmic retinochoroiditis (TRC) confirmed by aqueous humor analysis.

Design: Retrospective case series.

Methods: Retrospective analysis of 87 subjects with severe TRC, proven by positive Goldmann-Witmer coefficient (GWC), Toxoplasma gondii (T.

Purpose: To compare the superficial (FAZ-S) and deep foveal avascular zones (FAZ-D) of non-infectious anterior and posterior uveitis to healthy controls, using optical coherence tomography angiography (OCTA).

Methods: OCTA was performed on 74 eyes: 34 eyes with non-infectious posterior uveitis (with (post+CME) and without macular edema (post-CME)), 11 eyes with non-infectious anterior uveitis (with (ant+CME) and without macular edema (ant-CME)), and the control group which included 29 healthy eyes.

Results: Eyes suffering from non-infectious posterior uveitis presented with significantly larger FAZ-D when compared to healthy controls, both in the presence or in the absence of macular edema (p < 0.

Purpose: To describe the importance of a customized combined systemic and local therapy in the management of inflammatory choroidal neovascularization (iCNV).

Methods: Observational retrospective case series.

Results: Four iCNV cases, complicating posterior uveitis or panuveitis affecting young patients, are reported.

Uveitis is a sight-threatening primary intraocular inflammation of various origins in mainly young and active patients. Due to the absence of biomarkers in most of the cases, the current treatment of noninfectious entities remains nonspecific, using corticosteroids, conventional immunosuppressors, and more recently biological agents. Identification of regulatory T cells in different models of autoimmune uveitis together with the evaluation of this important subpopulation in different entities paved the way for new therapeutic strategies, in addition to exclusive pharmaceutical approaches.

Purpose: Macular edema is the leading cause of vision loss in bilateral chronic noninfectious posterior uveitis, and is currently being treated using corticosteroids, immunosuppressive agents, and biotherapies. The aim of this trial was to assess and compare the efficacy and safety of corticosteroids and interferon-α (IFN-α) in adults with such conditions.

Design: Randomized controlled trial.

Uveitis is one of the fields in ophthalmology where a tremendous evolution took place in the past 25 years. Not only did we gain access to more efficient, more targeted, and better tolerated therapies, but also in parallel precise and quantitative measurement methods developed allowing the clinician to evaluate these therapies and adjust therapeutic intervention with a high degree of precision. Objective and quantitative measurement of the global level of intraocular inflammation became possible for most inflammatory diseases with direct or spill-over anterior chamber inflammation, thanks to laser flare photometry.

Purpose: To retrospectively assess the frequency of ocular relapse and the possibility of long-term remission in patients treated with interferon (IFN) for severe uveitis associated with Behçet disease.

Methods: All patients were treated with an initial dosage of 3 million IU IFN three times a week. The main outcome measure was the number of relapses per person per year before, during, and after IFN treatment.

Purpose: To evaluate the changes of outer retinal tubulations (ORTs) as seen on spectral-domain optical coherence tomography (SD OCT) in eyes with neovascular age-related macular degeneration (AMD) where treatment was switched from intravitreal ranibizumab to intravitreal aflibercept.

Methods: This was a prospective study of eyes diagnosed with neovascular AMD and previously treated with >6 intravitreal ranibizumab injections and switched to aflibercept, conducted at a single centre (Department of Ophthalmology at Pitié Salpetriere Hospital, Paris VI University) from January to July 2015. Before and after treatment was switched from ranibizumab to aflibercept, SD-OCT was used to evaluate the presence of ORTs.
