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

Quantitative and Qualitative Evaluation of Explainable Deep Learning Methods for Ophthalmic Diagnosis [PDF]
arXiv, 2020 Background: The lack of explanations for the decisions made by algorithms such as deep learning has hampered their acceptance by the clinical community despite highly accurate results on multiple problems. Recently, attribution methods have emerged for explaining deep learning models, and they have been tested on medical imaging problems.

Vascular changes in diabetic retinopathy-a longitudinal study in the Nile rat. [PDF]
, 2019 Diabetic retinopathy is the most common microvascular complication of diabetes and is a major cause of blindness, but an understanding of the pathogenesis of the disease has been hampered by a lack of accurate animal models. Here, we explore the dynamics

Diverse roles of macrophages in intraocular neovascular diseases: a review [PDF]
International Journal of Ophthalmology, 2017 Macrophages are involved in angiogenesis, and might also contribute to the pathogenesis of intraocular neovascular diseases. Recent studies indicated that macrophages exert different functions in the process of intraocular neovascularization, and the ...

Fractal Dimension and Retinal Pathology: A Meta-analysis [PDF]
arXiv, 2021 Due to the fractal nature of retinal blood vessels, the retinal fractal dimension is a natural parameter for researchers to explore and has garnered interest as a potential diagnostic tool. This review aims to summarize the current scientific evidence regarding the relationship between fractal dimension and retinal pathology and thus assess the ...

The ratio of VEGF/PEDF expression in bone marrow mesenchymal stem cells regulates neovascularization [PDF]
, 2011 Angiogenesis, or neovascularization, is a finely balanced process controlled by pro- and anti-angiogenic factors. Vascular endothelial growth factor (VEGF) is a major pro-angiogenic factor, whereas pigment epithelial-derived factor (PEDF) is the most ...

Retinal Neovascular Disorders: Mouse Models for Drug Development Studies [PDF]
, 2011 Neovascularization is a hallmark of several eye diseases leading to visual impairment, and its epidemiological impact is substantial (Lee et al. 1998). In retinal degenerative disease models, neovascularization is the process by which the choroid and/or ...
