: To develop an algorithm for the diagnosis of Behçet's disease (BD) uveitis based on ocular findings.: 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.

Purpose: To investigate the effect of interferon alfa-2a on T regulatory (Treg) cells, T helper 17 (Th17) cells, and expression of Toll-like receptors (TLRs) in Behçet disease (BD) patients with uveitis.

Methods: Twenty-seven patients who received interferon alfa-2a for active BD uveitis despite conventional immunomodulatory therapies and healthy controls were enrolled. Peripheral blood Treg and Th17 cell frequencies were determined by flow cytometry as gated cells for CD3+CD4+Foxp3+ and CD3+CD4+IL17A+, respectively.

Purpose: To screen for psychological disorders in patients with active uveitis.

Methods: Patients were screened for depression (BDI-II), state anxiety (STAI-I), VR-QOL (NEI-VFQ-25), and HR-QOL (SF-36). Association of depression and anxiety with sociodemographic and clinical parameters and with VR-QOL and HR-QOL were analyzed.

Purpose: To report the efficacy and safety of interferon (IFN) α-2a in patients with cystoid macular edema (CME) associated with presumed ocular tuberculosis (TB).

Methods: We reviewed the clinical records of 5 patients with presumed ocular TB who had been treated with IFN α-2a for recurrent CME during or after completion of anti-tubercular therapy. IFN α-2a was administered at an initial dose of 3 million IU per day and then tapered after the initial response.

Purpose: To quantitatively analyze in vivo morphology of subfoveal choroid during an acute attack of Behçet uveitis.

Methods: In this prospective study, 28 patients with Behçet uveitis of ≤4-year duration, and 28 control subjects underwent enhanced depth imaging optical coherence tomography. A novel custom software was used to calculate choroidal stroma-to-choroidal vessel lumen ratio.

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.

Background And Objective: To compare the visualization of microaneurysms (MA) and the foveal avascular zone (FAZ) area using optical coherence tomography angiography (OCTA) versus fluorescein angiography (FA) in patients with diabetic macular edema (DME).

Patients And Methods: Patients were prospectively recruited for same-day imaging on spectral-domain OCTA and FA. OCTA images were automatically segmented into superficial (sOCTA) and deep (dOCTA) capillary plexuses.

Behçet disease is a chronic relapsing multisystem inflammatory disorder. Ocular involvement is characterized by a bilateral recurrent non-granulomatous panuveitis and retinal vasculitis. Posterior segment findings vary during the course of the disease, in parallel with the relapsing and remitting intraocular inflammation.

Purpose: To describe the effect of rituximab on full-field electroretinography (ERG) in a patient with nonparaneoplastic autoimmune retinopathy (npAIR).

Observations: A 58-year-old male patient with visual complaints, positive anti-retinal antibodies and negative work-up for cancer was diagnosed with npAIR. Visual acuity and ancillary tests were normal except abnormal ERG in both eyes.

Purpose: To describe nonglaucomatous retinal nerve fiber layer (RNFL) defects in patients with Behçet uveitis.

Design: Cross-sectional study and observational case series.

Methods: We reviewed the clinical photographs of patients with Behçet uveitis (n = 259), ocular toxoplasmosis (n = 120), and multiple sclerosis (MS)-associated uveitis (n = 40) for the presence of localized RNFL defects.

Unlabelled: Abstract Purpose: To evaluate agreement and estimate sensitivity and specificity of uveitis specialists' interpretation of ocular photographs in diagnosing Behçet uveitis.

Methods: Fourteen Turkish uveitis specialists, masked to demographic and clinical features of patients, independently labeled ocular photographs (29 Behçet/30 other diagnoses) as "Behçet uveitis" or "non-Behçet." Level of agreement was evaluated using kappa statistics.

Optical coherence tomography (OCT) is a non-contact noninvasive technique that allows in vivo imaging of the retina, choroid, optic nerve head, retinal nerve fiber layer, and the anterior structures of the eye. It was introduced into clinical practice two decades ago. Advances in OCT technology have been achieved by searching ultra-high-resolution OCT, adaptive optics OCT, eye-tracking OCT, and changes in signal detection technique from time-domain (TD) to spectral-domain (SD) detection.

Purpose: To describe 3 representative cases of autoimmune retinopathy (AIR).

Methods: Clinical records of patients with a diagnosis of AIR were analyzed for demographic data, clinical findings, ancillary and laboratory tests, and treatment employed.

Results: Three female patients diagnosed with AIR had bilateral reduction of electroretinogram amplitudes and elevation of visual field threshold within the central 30 degrees of the visual field that was disproportionately more severe than the clinical findings of retinal degeneration.

Purpose: To establish evidence-based recommendations regarding the use of anti-Tumor Necrosis Factor alpha (TNF-α) agents for managing uveitis patients.

Methods: Medline was searched via OVID (1950 - October Week 3, 2011) using a Cochrane highly sensitive search (phases 1 and 2). Additional literature searches were also conducted incuding the following databases: the Cochrane, LILACS and the TRIP Database.
