Endothelium Expression of Bcl-2 Is Essential for Normal and Pathological Ocular Vascularization.

PLoS ONE, 2015
Bcl-2 is an anti-apoptotic protein with important roles in vascular homeostasis and angiogenesis. Mice globally lacking Bcl-2 (Bcl-2 -/-) are small in stature and succumb to renal failure shortly after weaning as a result of renal hypoplasia/cystic ...

Rapid Regression of Exudative Maculopathy in Idiopathic Retinitis, Vasculitis, Aneurysms and Neuroretinitis Syndrome after Intravitreal Ranibizumab

Case Reports in Ophthalmology, 2012
The idiopathic retinitis, vasculitis, aneurysms and neuroretinitis syndrome is a rare retinal vascular disorder characterized by multiple leaking aneurysmal dilations, retinal vasculitis, neuroretinitis and peripheral vascular ischemia.

Spectrum of peripheral retinal ischemia in Wyburn-Mason syndrome

American Journal of Ophthalmology Case Reports, 2020
Purpose: We report two cases of Wyburn-Mason syndrome that illustrate the spectrum of peripheral retinal ischemia seen in this condition. Observations: A 12-year-old female presented with a retinal arteriovenous malformation and sclerotic vessels ...

Neovascularization Detection and Localization in Fundus Images Using Deep Learning

Sensors, 2021
Proliferative Diabetic Retinopathy (PDR) is a severe retinal disease that threatens diabetic patients. It is characterized by neovascularization in the retina and the optic disk. PDR clinical features contain highly intense retinal neovascularization and

High-resolution, in vivo multimodal photoacoustic microscopy, optical coherence tomography, and fluorescence microscopy imaging of rabbit retinal neovascularization

Light: Science & Applications, 2018
Photoacoustic microscopy (PAM) is an emerging imaging technology that can non-invasively visualize ocular structures in animal eyes. This report describes an integrated multimodality imaging system that combines PAM, optical coherence tomography (OCT ...

Sphingolipids as emerging mediators in retina degeneration [PDF]

, 2019
The sphingolipids ceramide (Cer), sphingosine-1-phosphate (S1P), sphingosine (Sph), and ceramide-1-phosphate (C1P) are key signaling molecules that regulate major cellular functions.

Identifying circRNA-associated-ceRNA networks in retinal neovascularization in mice

International Journal of Medical Sciences, 2019
Retinal neovascularization is a complication which caused human vision loss severely. It has been shown that circular RNAs (circRNAs) play essential roles in gene regulation.

Ultrastructure of neurovascular changes in human diabetic retinopathy [PDF]

, 2018
The previous concept regarding diabetic retinopathy assigned a primary role to hyperglycemia-induced microvascular alterations, while neuronal and glial abnormalities were considered to be secondary to either ischemia or exudation.

ADAM9 Is Involved in Pathological Retinal Neovascularization [PDF]

Molecular and Cellular Biology, 2009
Pathological ocular neovascularization, caused by diabetic retinopathy, age-related macular degeneration, or retinopathy of prematurity, is a leading cause of blindness, yet much remains to be learned about its underlying causes. Here we used oxygen-induced retinopathy (OIR) and laser-induced choroidal neovascularization (CNV) to assess the ...

Sacrificial Biofabrication for Vascularization: Concept, Materials, Technologies, and Applications

Advanced Materials, EarlyView.
Vasculature is indispensable for tissue viability in regenerative medicine. The sacrificial biofabrication enables precise fabrication of vascular channels by using temporary templates that are subsequently removed. This review defines the concept and delves into sacrificial materials, surrounding materials, fabrication technologies, and biomedical ...
