Peripapillary Choroidal Vascularity Index and Microstructure of Parapapillary Atrophy

open access: yesInvestigative Opthalmology & Visual Science, 2019
To investigate the association between the microstructure of β-zone parapapillary atrophy (βPPA) and choroidal vascularity index (CVI) determined by spectral-domain optical coherence tomography (SD-OCT) in glaucomatous eyes.A total of 160 eyes of 160 primary open-angle glaucoma patients with βPPA were included. Total choroidal area (TCA), luminal area (

Synergistic inhibition of macular vascular permeability in diabetic edema: Ginsenoside Rg3 enhances ranibizumab efficacy by targeting angiopoietin‐like protein 4 and vascular endothelial growth factor via neuropilin/RhoA signaling

open access: yesJournal of Diabetes Investigation, EarlyView.
Molecular mechanism of synergistic antagonism of ANGPTL4 and VEGF by ginsenoside Rg3 combined with ranibizumab, regulating the NRP/RhoA pathway to inhibit macular edema. ABSTRACT Aims This study investigated the molecular mechanisms by which ginsenoside Rg3 combined with ranibizumab alleviates diabetic macular edema (DME), focusing on antagonizing ...

Techniques for subretinal injections in animals

open access: yesVeterinary Ophthalmology, Volume 28, Issue 2, Page 506-518, March 2025.
Abstract Subretinal injections are not commonly performed during clinical treatment of animals but are frequently used in laboratory animal models to assess therapeutic efficacy and safety of gene and cell therapy products. Veterinary ophthalmologists are often employed to perform the injections in the laboratory animal setting, due to knowledge of ...

Effects of metformin on retinoblastoma growth in vitro and in vivo [PDF]

open access: yes, 2014
Recent studies suggest that the anti-diabetic drug metformin may reduce the risk of cancer and have anti-proliferative effects for some but not all cancers. In this study, we examined the effects of metformin on human retinoblastoma cell proliferation in

Women in space: A review of known physiological adaptations and health perspectives

open access: yesExperimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Choroidal Vascularity Index (CVI)--A Novel Optical Coherence Tomography Parameter for Monitoring Patients with Panuveitis?

open access: yesPLoS ONE, 2016
PurposeTo compute choroidal vascularity index (CVI) using an image binarization tool on enhanced depth imaging (EDI)-optical coherence tomography (OCT) scans as a non-invasive optical tool to monitor progression in panuveitis and to investigate the ...

An eye on long‐duration spaceflight: Controversies, countermeasures and challenges

open access: yesExperimental Physiology, EarlyView.
Abstract Space flight‐associated neuroocular syndrome (SANS) is a consequence of long‐duration space flight and is detected in two‐thirds of astronauts. In‐flight, this can cause a change in the refraction of the eyes, requiring graded hypermetropic ‘superfocus adjustable’ glasses, optic nerve head oedema and choroidal folds.
