Sporadic Retinal Astrocytic Hamartoma Mimicking Retinoblastoma in a Child: A Case Report and Literature Review

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Retinal astrocytichamartoma (RAH) is a rare benign glial neoplasm most commonly associated with tuberous sclerosis complex (TSC). Sporadic cases, occurring in the absence of systemic phakomatosis, are uncommon and may closely mimic retinoblastoma, particularly when presenting with a calcified intraocular mass, creating a diagnostic challenge ...

Changes in Vitreoretinal Adhesion With Age and Region in Human and Sheep Eyes

Frontiers in Bioengineering and Biotechnology, 2018
While several studies have qualitatively investigated age- and region-dependent adhesion between the vitreous and retina, no studies have directly measured the vitreoretinal strength of adhesion.

Cascade‐targeted intervention of the NLRP3 inflammasome and downstream angiogenesis by curcumin nanoparticles for ocular neovascularization therapy

Clinical and Translational Medicine, Volume 16, Issue 9, September 2026.
Ultrasound‐microreactor synthesizes monodisperse 125 nm Cur‐NPs with enhanced solubility. Cur‐NPs suppress VEGF signaling and retinal neovascularization via the NLRP3 axis. Multi‐omics profiling reveals that Cur‐NPs reprogram retinal microglia and metabolic pathways.

Revised Swedish visual field standards for a driver's licence: Threshold perimetry as a predictor of eligibility according to the current Swedish and current Norwegian suprathreshold standards

Acta Ophthalmologica, Volume 104, Issue 6, Page e709-e717, September 2026.
Abstract Purpose To explore whether threshold perimetry can predict fulfilment of the current Swedish and current Norwegian Esterman perimetry standards for Group 1 driver's licence, and differences in compliance between the former and current Swedish visual field standards.

Partial Posterior Vitreous Detachment: New Capabilities of Improving Diagnosis and Surgical Approach Using SD-OCT

, 2014
Introduction: Partial posterior vitreous detachment (PPVD) is considered the first stage of posterior vitreous detachment (PVD). Possible complications of PPVD are vitreomacular traction syndrome and macular pucker.

Processionary Moth Exposure in Europe: Toxic–Irritant and Immunoglobulin E‐Mediated Endotypes, Diagnosis and Management

Clinical &Experimental Allergy, Volume 56, Issue 9, Page 1017-1030, September 2026.
Most reactions are toxic–irritant, driven by epithelial injury and neuro‐inflammatory activation. IgE‐mediated allergy is less common but may cause immediate systemic reactions. Endotype differentiation guides diagnosis, risk stratification and management.

Sensitivity of ultrasound in detecting posterior segment pathology in mature cataract patients: A prospective observational study

Asian Journal of Medical Sciences
Background: Ocular B-mode ultrasonography (USG) acts as a valuable adjuvant for assessing the posterior segment of the eye in mature cataract, especially when fundus visualization is obscured by media opacities such as vitreous hemorrhage, asteroid ...

A mechanical model of posterior vitreous detachment and generation of vitreoretinal tractions

, 2020
We propose a mechanical model of generation of vitreoretinal tractions in the presence of posterior vitreous detachment (PVD). PVD is a common occurrence with aging, and it consists in the separation of the vitreous body from the retina at the back pole ...

Pre‐ and Post‐Phacoemulsification Morphologic Iridocorneal Angle Analysis by Anterior Segment Gonioscopic Imaging as a Predictor of Postoperative Glaucoma in Dogs

Veterinary Ophthalmology, Volume 29, Issue 5, September 2026.
ABSTRACT Objective To serially assess iridocorneal angle (ICA) gonioscopic morphology following phacoemulsification in dogs and to determine whether postoperative changes are associated with the development aphakic/pseudophakic glaucoma. Animals Studied Client‐owned dogs presented for cataract removal by phacoemulsification.

Black flashes (dysphotopsia) as a symptom of vitreo-papillary traction in evolving posterior vitreous detachment – An optical coherence tomography case series

American Journal of Ophthalmology Case Reports
Purpose: We present three cases of evolving posterior vitreous detachment (PVD) in which patients experienced black flashes, known as negative dysphotopsia (ND), and were found to have vitreo-papillary adhesion at the optic nerve head. Observations: A 53-
