Retinal blood vessels segmentation using classical edge detection filters and the neural network
Retinal blood vessels analysis is of interest for medical screening, especially in the diagnosis of diabetic retinopathy. In this paper, we propose a new method for the segmentation of blood vessels in retinal photographs.

A Recursive Bayesian Approach To Describe Retinal Vasculature Geometry [PDF]
Demographic studies suggest that changes in the retinal vasculature geometry, especially in vessel width, are associated with the incidence or progression of eye-related or systemic diseases. To date, the main information source for width estimation from

Age and diabetes related changes of the retinal capillaries: an ultrastructural and immunohistochemical study [PDF]
Normal human aging and diabetes are associated with a gradual decrease of cerebral flow in the brain with changes in vascular architecture. Thickening of the capillary basement membrane and microvascular fibrosis are evident in the central nervous system

Mechanisms underlying microglial colonization of developing neural retina in zebrafish
Microglia are brain-resident macrophages that function as the first line of defense in brain. Embryonic microglial precursors originate in peripheral mesoderm and migrate into the brain during development.
