Techniques for subretinal injections in animals

Veterinary 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 ...

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

Experimental 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.

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

Experimental 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.

A computational model for retinal haemodynamics under gravitational and postural variations

The Journal of Physiology, EarlyView.
Abstract figure legend The haemodynamic impact of gravitational and postural changes on the retina, and its relevance to spaceflight associated neuro‐ocular syndrome (SANS), remains incompletely characterized. This study assesses retinal haemodynamics from upright to head‐down tilt using a lumped‐parameter model that dynamically couples intraocular ...

Diurnal variation in subfoveal and peripapillary choroidal vascularity index in healthy eyes

Indian Journal of Ophthalmology, 2019
Purpose: To report the diurnal variation in choroidal vascularity index (CVI) in subfoveal (SF-CVI) and peripapillary area in healthy eyes. Methods: The study was a cross-sectional study including 12 healthy subjects.

DELP Treatment on Vision and Retinal Microcirculation in Patients With Acute Ischemic Stroke: Report of Five Cases and Literature Review

Therapeutic Apheresis and Dialysis, Volume 30, Issue 2, Page 168-175, April 2026.
ABSTRACT Background The delipid extracorporeal lipoprotein filter from plasma (DELP) treatment can effectively reduce blood lipid, increase blood flow, and improve neurological deficits in patients with acute ischemic stroke (AIS). However, its effect on vision and retinal microcirculation in stroke patients has never been reported.

Overproduction of 42 Amino Acids Long Amyloid Beta Leads to Activation of Secretory Autophagy and Development of Drusen‐Like Structures Originating From Retinal Pigment Epithelium

The FASEB Journal, Volume 40, Issue 5, 15 March 2026.
The role of 42 amino acids long amyloid beta (Aβ) in the retinal pigment epithelium (RPE) was investigated using 5xFAD mice model overproducing Aβ. The RPE cells of 5xFAD mice showed increased oxidative stress, accumulation of autophagy‐destined proteins, increased expression of secretory autophagy markers, and increase in epithelial‐to‐mesenchymal ...
