Putting the Puzzle Together: Case Report of Parinaud Syndrome in a Pediatric Patient.

J Binocul Vis Ocul Motil

January 2025

Department of Ophthalmology, Vanderbilt Eye Institute, Nashville, Tennessee.

Parinaud syndrome, also known as dorsal midbrain syndrome, is a condition affecting the dorsal midbrain region of the brainstem that presents with a triad of ophthalmic clinical findings, including upgaze paresis, convergence retraction nystagmus, and light-near dissociation. This case report will discuss the clinical presentation of Parinaud syndrome in a four-year-old patient who was seen in an out-patient clinic for intermittent exotropia 5 months after a suboccipital craniotomy resection of a pineal mass and ventriculoperitoneal (VP) shunt placement for associated hydrocephalus. Current literature is relatively sparse regarding the presentation of Parinaud syndrome in the pediatric population, with little known about prognosis and potential for recovery.

Uncorrected refractive error is a key cause of childhood visual impairment in the United States. As pediatric vision issues are often asymptomatic, vision screenings are essential to identify children's eye problems. Despite the importance of vision for children's health, well-being, and academic achievement, challenges remain in ensuring that children have equitable access to vision screenings and follow-up eye care.

Arq Bras Oftalmol

January 2025

Department of Ophthalmology, Guangdong Eye Institute, Guangdong General Hospital, Guangdong Academy of Medical Sciences. No. 106 Zhongshan Er Road, Guangzhou 510080, China.

Purpose: Although the orthokeratology effects on corneal biomechanics have been proven with clinical trials, reports of stiffness parameter change are scarce. This study investigated the short-term orthokeratology effects in pediatric myopia and compared stiffness parameter changes to those published in recent clinical investigations. This prospective study aimed to investigate corneal biomechanics changes induced by short-term overnight orthokeratology treatment, focusing on stiffness parameter at A1 and stress-strain index.

Purpose: To evaluate intermediate-term outcomes and complications associated with Ahmed glaucoma valve (AGV) implantation in eyes with type 1 keratoprosthesis (KPro).

Methods: We retrospectively reviewed records of 43 eyes of 43 Indian patients with type 1 KPro and AGV from 2009 to 2021 with a minimum of 6-months of follow-up. Five eyes that had AGV before KPro were excluded, leaving 38 eyes for analysis.

Due to its anatomical and physiological similarities to the human eye, the porcine eye serves as a robust model for biomedical research and ocular toxicity assessment. An air/liquid corneal culture system using porcine eyes was developed, and ex vivo epithelial wound healing was utilized as a critical parameter for these studies. Fresh pig corneas were processed for organ culture, with or without epithelial wounding.

Enantiomer-Dependent Supramolecular Antibacterial Therapy for Drug-Resistant Bacterial Keratitis.

Langmuir

January 2025

National Engineering Research Center of Ophthalmology and Optometry, Eye Hospital, Wenzhou Medical University, Wenzhou 325027, China.

Bacteria have the potential to exhibit divergent stereochemical preferences for different levels of chiral structures, including from molecule, supramolecule, to nanomicroscale helical structure. Accordingly, the structure-activity relationship between chirality and bactericidal activity remains uncertain. In this study, we seek to understand the multivalent molecular chirality effect of chiral supramolecular polymers on antibacterial activity.

3D ophthalmic ultrasonography at the slit lamp using existing ultrasound systems.

PLoS One

January 2025

Department of Ophthalmology, Gavin Herbert Eye Institute, University of California Irvine, Irvine, California, United States of America.

Purpose: This study aims to explore the feasibility and performance of three-dimensional ultrasound (3DUS) imaging in ophthalmology using commercially available ultrasound probes adapted to a slit lamp.

Significance: Despite ultrasound's long-standing application in eye care for visualizing ocular components, the evolution of 3DUS technology has remained inactive, with limited development and commercial availability. This study introduces a novel method that could potentially enhance ophthalmic diagnostics and treatment planning by providing comprehensive 3D views of ocular structures using existing ultrasound probes adapted to the conventional slit lamp.

Integrin Trafficking, Fibronectin Architecture, and Glomerular Injury upon AdipoR1 Depletion.

J Am Soc Nephrol

January 2025

Research Program for Clinical and Molecular Metabolism, Faculty of Medicine, University of Helsinki, Helsinki, Finland.

Background: Deficiency of adiponectin and its downstream signaling may contribute to the pathogenesis of kidney injury in type 2 diabetes. Adiponectin activates intracellular signaling via adiponectin receptors 1 and 2 (AdipoR1 and AdipoR2), but the role of AdipoR-mediated signaling in glomerular injury in type 2 diabetes remains unknown.

Methods: The expression of AdipoR1 in the kidneys of people with type 2 diabetes and the expression of podocyte proteins or injury markers in the kidneys of AdipoR1-knockout (AdipoR1-KO) mice and immortalized AdipoR1-deficient human podocytes were investigated by immunohistochemistry and immunoblotting.
