Simultaneous occlusion of three cilioretinal arteries following scleral buckling surgery under local anesthesia [PDF]

open access: yes, 2016
BACKGROUND: Cilioretinal artery (CRA) occlusions are rare in young patients. In these cases, the most commonly associated causes are considered to be the same as those implicated in central retina artery occlusions, such as vasculitic processes ...

Single‐Cell RNA Sequencing of Retina Reveals Nna1 Upregulation in Myopic Diabetic Retinopathy as a Protective Factor Against Diabetic Damage

open access: yesAdvanced Science, Volume 13, Issue 5, 27 January 2026.
This study investigates a schematic overview of the mechanistic pathways. The relationship between myopia and DR has long been of clinical interest. In diabetic mice, Nna1 expression is downregulated, whereas in diabetic mice with FDM, Nna1 expression is upregulated–particularly in Müller cells–accompanied by decreased vascular endothelial growth ...

Retinal vein occlusion

open access: yesZdravniški Vestnik, 2011
Retinal vein occlusion is a common disease, especially in the elderly, and is associated with significant visual morbidity, as a consequence of persistent macular oedema, macular ischemia, and in the advanced stages of the disease, due to retinal or iris

Continuous Suppression of Pathological Retinal and Choroidal Neovascularization in Cynomolgus Monkeys via Noninvasive Ophthalmic Delivery of a Novel Anti‐VEGFA Nanobody and Proprietary Penetratin Analog Formulation

open access: yesAdvanced Science, Volume 13, Issue 1, 5 January 2026.
Pathological retinal/choroidal neovascularization drives vision loss in DR and AMD. Current anti‐VEGF injections, while effective, require invasive, frequent administration. Pene/LQ015, is developed a novel topical anti‐VEGFA nanobody formulation achieving therapeutic intraocular levels through penetratin analog‐enhanced delivery.

Cortical Microvascular Pulsatility in the Aging Mouse Brain and the Confounding Effects of Anesthesia

open access: yesAdvanced Science, Volume 13, Issue 4, 19 January 2026.
Multi‐modal optical imaging reveals microvascular pulsatility in the brain cortex of awake and anaesthetized mice. Awake hemodynamics in male mice are found to be remarkably stable until late life, with flow pulsatility being significantly higher than in females, despite similar average perfusion.

Ipsilateral, Multi-Phasic Retinal Vascular Events following Intralesional Triamcinolone Acetonide Injection for Earlobe Keloid: A Case Report

open access: yesCase Reports in Ophthalmology
Introduction: Intralesional triamcinolone acetonide is a widely used treatment for scarring skin conditions such as keloid and is known to have retinal vascular complications if administered in the periocular region.

Combined occlusion of branch retinal artery and vein secondary to prepapillary arterial loops

open access: yesIndian Journal of Ophthalmology, 2015
A middle-aged diabetic and hypertensive man presented with diminished vision in the left eye. Fundus examination revealed prepapillary arterial loops, but with features of venous rather than arterial occlusion.

Evaluation of Nonperfused Retinal Vessels in Ischemic Retinopathy [PDF]

open access: yes, 2016
Purpose: Retinal ischemia has been traditionally assessed by fluorescein angiography, visualizing perfused vessels. However, this method does not provide any information about nonperfused vessels, and although it is often assumed that vessels in ischemic
