Combining Fine- and Coarse-Grained Classifiers for Diabetic Retinopathy Detection

, 2020
Visual artefacts of early diabetic retinopathy in retinal fundus images are usually small in size, inconspicuous, and scattered all over retina. Detecting diabetic retinopathy requires physicians to look at the whole image and fixate on some specific ...

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 ...

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 ...
