Ultrasonographic evaluation of optic nerve sheath diameter in patients severe traumatic brain injury: a comparison with intraparenchymal pressure monitoring.
Neurosurg Rev
January 2025
Department of Surgery, School of Medicine, Federal University of Minas Gerais, Belo Horizonte, Minas Gerais, Brazil.
Objective: Increased intracranial pressure (ICP) can worsen the clinical condition of traumatic brain injury (TBI) patients. One non-invasive and easily bedside-performed technique to estimate ICP is ultrasonographic measurement of optic nerve sheath diameter (ONSD). This study aimed to analyze ONSD and correlate it with ICP values obtained by intraparenchymal monitoring to establish the ONSD threshold value for elevated ICP and reference range of ONSD in severe TBI patients.

Introduction: Retinal capillary hemangioma (RCH) is a benign vascular hamartoma that can occur sporadically or as a manifestation of Von Hippel-Lindau (VHL) disease. If left untreated, it results in adverse ocular complications depending on its location and eventual visual loss.
Case Presentation: We present a 50-year-old man who was a known case of VHL with history of left eye vision loss in the left eye at the age of 30 years.
In vivo imaging of mitochondrial function in normal, glaucoma suspect, and glaucoma eyes.
PLoS One
January 2025
Department of Ophthalmology, University of Washington, Seattle, WA, United States of America.
To investigate macula and optic nerve head (ONH) mitochondrial metabolic activity using flavoprotein fluorescence (FPF) in normal, glaucoma suspect (GS), and open-angle glaucoma (OAG) eyes we performed a cross-sectional, observational study of FPF in normal, GS, and OAG eyes. The macula and ONH of each eye was scanned and analyzed with a commercially available FPF measuring device (OcuMet Beacon, OcuSciences Inc., Ann Arbor, MI).

Invest Ophthalmol Vis Sci
January 2025
NIHR Biomedical Research Centre, Moorfields Eye Hospital NHS Foundation Trust and UCL Institute of Ophthalmology, London, United Kingdom.
Purpose: To investigate the effect of average intraocular pressure (IOP) on the true rate of glaucoma progression (RoP) in the United Kingdom Glaucoma Treatment Study (UKGTS).
Methods: UKGTS participants were randomized to placebo or Latanoprost drops and monitored for up to two years with visual field tests (VF, 24-2 SITA standard), IOP measurements, and optic nerve imaging. We included eyes with at least three structural or functional assessments (VF with <15% false-positive errors).
Optical Coherence Tomography Angiography in Patients With the Boston Keratoprosthesis Type 1.
Cornea
January 2025
Department of Ophthalmology, Massachusetts Eye and Ear, Harvard Medical School, Boston, MA.
Purpose: To report on optical coherence tomography angiography (OCTA) in patients with a type 1 Boston keratoprosthesis (KPro) and determine its feasibility through assessment of imaging artifacts.
Methods: KPro and non-KPro subjects were matched for age, gender, and glaucoma diagnosis. OCTA images of the peripapillary optic nerve were obtained, reviewed by 2 readers masked to the diagnosis for artifacts and usability, and used for microvascular measurements.
