  • Treatment began with infliximab and vitreoretinal surgery, but he experienced several adverse reactions, including an infusion reaction, hepatotoxicity, and complications from other therapies.
  • After 33 months, despite being in clinical remission, he faced ongoing inflammation in his right eye and had a poor visual acuity, highlighting the need for careful monitoring and adjustments in immunomodulatory treatment for Behçet uveitis.

Objectives: The aims of this study were to describe the clinical presentation and treatment modalities of acute retinal necrosis (ARN) and to evaluate complications and clinical outcomes according to the extent of retinal involvement at initial presentation.

Materials And Methods: The medical records of 52 patients diagnosed with ARN were reviewed and 48 were included in the study. Patients were categorized into two groups according to the extent of retinitis at presentation: retinal involvement of 1-2 quadrants (Group A) or 3-4 quadrants (Group B).

: 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 report the results of tocilizumab (TCZ) treatment in patients with Behçet uveitis (BU) who had failed conventional, interferon alpha, and anti-Tumor necrosis factor-alpha therapy.

Methods: We reviewed the records of five patients with BU treated with monthly infusions of TCZ 8 mg/kg. Outcome measures were visual acuity, anterior chamber cells, laser flare meter (LFM) readings, vitreous haze, central macular thickness (CMT), and fluorescein angiography (FA) score.

Bullous central serous chorioretinopathy (CSCR) is a rare variant of CSCR characterized by severe serous retinal detachment which especially involves the inferior quadrants. Corticosteroid therapy administered for systemic or ocular misdiagnoses may induce and exacerbate CSCR. The purpose of this study was to report diagnosis and treatment results of an unusual case of bullous CSCR induced by systemic and periocular corticosteroid therapy received at another medical center due to a misdiagnosis of Vogt-Koyanagi-Harada disease.

Brucellosis may be associated with a wide range of ophthalmic manifestations including endophthalmitis, which is a sight-threatening condition that needs to be rapidly recognized and treated to avoid permanent visual loss A 26-year-old female with a 6-month history of vision loss in the left eye was treated with high dose systemic corticosteroids and azathioprine with an initial misdiagnosis elsewhere. A dense vitreous haze with opacities at the posterior hyaloid and a wide area of retinochoroiditis led to the diagnosis of endogenous endophthalmitis at presentation to us. The vitreous sample and blood cultures demonstrated growth of She received 6 months of systemic antibiotherapy, which resulted in resolution of inflammation; however, visual acuity remained poor due to irreversible damage.

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.

Pediatric uveitis may be a serious health problem because of the lifetime burden of vision loss due to severe complications if the problem is not adequately treated. Juvenile idiopathic arthritis (JIA)-associated uveitis is characterized by insidious onset and potentially blinding chronic anterior uveitis. Periodic ophthalmologic screening is of utmost importance for early diagnosis of uveitis.
