PURPOSE: Uveitis is a common, sight-threatening inflammatory ocular disease and is the main cause of blindness, which is caused by autoimmune response, infection, and injury. The contribution of 14-3-3ζ in uveitis remains obscure. This study aims to investigate the role of 14-3-3ζ in regulating ferroptosis in retinal inflammation and its contribution to uveitis. METHODS: A lipopolysaccharide (LPS)-induced uveitis mouse model and BV-2 cell line were used to examine the effect of LPS stimulation on the expression of 14-3-3ζ and ferroptosis in microglia...

PURPOSE: To document vascular changes in eyes with post-fever retinitis (PFR) pre and post treatment demonstrated using optical coherence tomography angiography (OCTA). METHODS: This is a retrospective observational case series wherein patients with PFR were retrospectively evaluated for changes in the retinal vasculature during the course of disease using OCTA. RESULTS: At presentation, OCTA revealed flow void areas in superficial and deep capillary plexus (SCP and DCP) corresponding to the areas of retinitis...

INTRODUCTION: Uveitis may occur during approximately 1-3% of MS patients, corresponding to 10 times higher than in the general population. The development of uveitis is not currently considered as an inflammatory relapse of MS. There are no clinical guidelines for treating. MS with concomitant uveitis requiring systemic treatment. PURPOSES: To analyze clinical and therapeutic characteristics of uveitis in patients with MS and the impact of MS treatment on the progression of uveitis...

PURPOSE: The aim of this study was to describe the clinical presentation, histopathologic characteristics, and management of phacolytic glaucoma. PATIENTS AND METHODS: The database at the Florida Lions Ocular Pathology Laboratory was searched for surgical specimens at the Bascom Palmer Eye Institute. Patients with a diagnosis of "phacolytic glaucoma" on cytopathology between the years of 1997 and 2023 were included ( n  = 15). Patient demographics, anatomic site, laterality, clinical features, and ocular examination findings were obtained from available medical records...

PURPOSE: To present an atypical case of severe bilateral ocular toxoplasmosis with systemic involvement that initially mimicked an autoimmune etiology, posing challenges to its diagnosis and treatment. CASE REPORT: A 39-year-old immunocompetent male was admitted to the hospital due to a presumed pulmonary thromboembolism concomitant with an abrupt onset of vision loss. Initial differential diagnoses included antiphospholipid syndrome and systemic lupus erythematosus, prompting the administration of corticosteroid pulses and rituximab...

PURPOSE: To investigate the association of clinical findings and indocyanine green angiography (ICGA) score with inflammatory markers derived from complete blood count (CBC) parameters in patients with Vogt-Koyanagi-Harada (VKH) to determine the diagnostic and predictive role. METHODS: Demographic characteristics, presenting complaints, ocular findings, optical coherence tomography findings, ICGA scores and best corrected visual acuity were recorded in treatment-naive VKH patients at presentation...

PURPOSE: To study the role of the complement system's C3 and C4 fractions in the pathogenesis of different types of uveitis. METHODS: A prospective case-control study. 118 patients were enrolled. The control group comprised 60 patients who were otherwise healthy people undergoing cataract or pterygium surgery, whereas the uveitis patients group consisted of 58 people. The levels of C3 and C4 fractions in the blood and in the aqueous humor for both groups were evaluated and compared...

We report two patients who displayed evidence of localized ocular inflammation after CAR T-cell infusion. To manage the resulting severe visual impairment, systemic corticosteroids were administered to both patients. This treatment led to a reduction in local inflammation and restored vision in one of the patients.

PURPOSE: To report two cases of non-granulomatous unilateral anterior uveitis in two female patients associated with autoimmune liver diseases (ALD), emphasizing the possibility of this rare coexistence as a polyautoimmunity phenomenon. CASE DESCRIPTIONS: Case 1: An 18-year-old female with a history of congenital renal hypoplasia and metabolic syndrome presented with anterior uveitis in OS and a history of jaundice, blood elevated hepatic enzymes, and cholangioresonance compatible with primary sclerosing cholangitis (PSC)...

AIM: To assess the relationship between systemic inflammation markers and ocular surface parameters in hazelnut harvesters. MATERIAL AND METHOD: This prospective study included 30 patients presenting with moderate ocular surface diseases during the hazelnut harvesting season. A detailed ophthalmological examination was performed during the harvesting season and the first month after the end of treatment (control). Schirmer test, tear break-up time (TBUT), and ocular surface disease index (OSDI) scores were determined...

PURPOSE: To examine the real-world management and outcomes of uveitic cystoid macular oedema (CME). DESIGN: Retrospective study. METHODS: Patients with uveitic CME were identified from the Inflammatory Eye Disease database. 248 eyes of 218 patients with uveitic CME were identified. Main Outcome Measures : Time to resolution, time to recurrence and vision loss. RESULTS: Median age at time of CME was 51.7 years [IQR 37...

PURPOSE: To report a case of uveitis associated with multiple sclerosis (MS) that was refractory to multiple lines of therapy but achieved remission with tocilizumab. METHODS: We conducted a retrospective analysis of the patient's medical record including clinical, biological and imaging data. RESULTS: A 33-year-old female patient with a history of MS inactive for 5 years on teriflunomide, and no significant medical or ophthalmological history, presented with bilateral granulomatous panuveitis...

PURPOSE: Atypical hemolytic uremic syndrome (aHUS) is a rare progressive thrombotic microangiopathy caused by overactivation in the alternative complement pathway. A wide spectrum of environmental triggers, such as viruses, vaccination, drugs, pregnancy, neoplasms, transplant, and autoimmune diseases can cause aHUS in genetically susceptible individuals. In this report, the diagnosis and treatment process of aHUS and bilateral retinal venous occlusion (RVO) will be presented. METHODS: Single-case, retrospective management of ophthalmological and systemic manifestations...
