Swarm Intelligence Techniques in Segmenting Human Retinal Vasculature

open access: yesInternational Journal of Recent Technology and Engineering (IJRTE), 2019
Vasculature of human retina furnishes information concerning various eye related ailments and also assists in lesions detection. Severity of the eye diseases can be discerned from pathological conditions related to changes in the retinal vasculature. In this work, for pre-processing, Contrast Limited Adaptive Histogram Equalization (CLAHE) and average ...

Microendoscopy of the Anterior Segment Vasculature in the Rabbit Eye

open access: yesOphthalmic Research, 1989
Intraocular microendoscopy is introduced as a new method which allows a direct in vivo observation of the microvasculature of the eye. Using video equipment, a quantitative evaluation of changes in vessel diameters, e.g. after administration of vasoactive agents, and an estimation of blood oxygenation are possible. Experimental studies with fluorescent
