This study investigated corneal endothelial cell density (ECD) in pseudoexfoliation (PEX) syndrome patients and evaluated the clinical factors associated with ECD for 51 eyes of 41 phakic patients with pseudoexfoliation (PEX group) and 201 eyes of 117 patients with age-related cataracts (control group) as an age-matched control to the PEX group. Variable clinical factors, including ECD, central corneal thickness (CCT), anterior chamber depth (ACD), number of anti-glaucoma eye drops and severity of PEX, were examined using multivariate analyses. Severity of PEX was as follows: Mild in 28 eyes, Moderate in 16 eyes, and Severe in 7 eyes. The mean ECD was 2,548 ± 409 cells/mm in the PEX group and 2,757 ± 282 cells/mm in the control group, respectively, and ECD in the PEX group was significantly lower than that in the control group (P = 0.02). Multivariate analyses revealed that the severity of PEX [-176.8, 95% confidence interval (CI) (-244.5, -109.2), P < 0.01] was significantly associated with lower ECD. Accumulation of PEX materials contributed to early corneal endothelial decompensation.

Anterior chamber morphological and refractive outcomes following phacoemulsification in pseudoexfoliative eyes: A case-control study.
Eur J Ophthalmol
January 2025
Ophthalmology Department, ULS São José, Lisboa, Portugal.
Purpose: To compare changes in angle morphology, anterior chamber depth (ACD) and refractive prediction error (PE) after phacoemulsification between pseudoexfoliative (PEX) and non-PEX eyes.
Methods: Prospective case-control study of eyes submitted to cataract surgery. Biometric data and angle parameters - Anterior Chamber Angle (ACA), Angle Opening Distance (AOD), Scleral Spur Angles (SSA) and Trabecular Iris Space Area (TISA) - were measured preoperatively and 1-month postoperatively through swept-source anterior segment optical coherence tomography.
C-Reactive Protein Changes in Adult and Pediatric People With Cystic Fibrosis During Treatment of Pulmonary Exacerbations.

Objective: Although studies have examined changes in C-reactive protein (CRP) during pulmonary exacerbations (PEX) in people with cystic fibrosis (PwCF), few have evaluated CRP profiles across age groups. Here, we characterize age-related CRP responses to PEX treatment.
Methods: We measured CRP concentrations at the beginning and end of intravenous (IV) antibiotic therapy for PEX in 100 pediatric and 147 adult PwCF at 10 US CF Centers.

Introduction: Zellweger spectrum disorder (ZSD) refers to a group of autosomal recessive genetic disorders that affect multiple organ systems and are predominantly caused by pathogenic variants in PEX genes. ZSD present a wide clinical spectrum, ranging from the most severe form, Zellweger syndrome, to the mildest form, Heimler syndrome.
Case Report: A 14-month-old male patient was brought to our clinic with recent-onset ocular tremors and unsteady gait.

Objectives This study aimed to identify the etiology and the direction of dislocation of the natural crystalline lens or intraocular lens (IOL) in IOL intrascleral fixation surgery and to determine the change in intraocular pressure (IOP) after surgery. Methods We retrospectively investigated the diagnosis, direction of lens and IOL dislocation, and IOP before and after surgery (preoperatively and one day, one week, and one month postoperatively) in 236 eyes from 228 patients who underwent IOL intrascleral fixation at Chiba University Hospital between February 2015 and September 2020. Results IOL intrascleral fixation was performed in 48 (20.

Purpose: To investigate the role of hematological and atherogenic biomarkers in evaluating systemic inflammation and cardiovascular risk in patients with pseudoexfoliation syndrome.
Methods: This retrospective study included 200 patients, 90 with pseudoexfoliation (PEX) syndrome (Group 1) and 110 healthy controls (Group 2). Twelve-hour fasting blood samples were collected to measure complete blood count, neutrophil/lymphocyte ratio (NLR), monocyte/lymphocyte ratio (MLR), platelet/lymphocyte ratio (PLR), systemic immune-inflammation index (SII) (neutrophil x platelet/lymphocyte), systemic inflammatory response index (SIRI) (neutrophil x monocyte/lymphocyte), pan-immune inflammation value (PIV) (neutrophil x platelet x monocyte/lymphocyte), C-reactive protein (CRP), uric acid, glucose, triglycerides (TG), total cholesterol, HDL, LDL, non-HDL, and triglyceride-glucose (TyG) index (Ln (TG [mg/dL] × glucose [mg/dL]/2)).
