purpose: to present 3 rare cases of benign flecked retina syndrome. patients and finding: a 19-year-old female patient presented with fundus albipunctatus appearance in fundoscopy without night blindness and normal dark adaptation time on electeroretinography (erg). after 9 years of follow up, no change in visual acuity, erg, or other ophthalmologic examinations was seen. two members of her fam...

Purpose. To compare treatment areas and navigated macular laser photocoagulation (MLP) plans suggested by retro-mode scanning laser ophthalmoscopy (RM-SLO) image versus optical coherence tomography (OCT) central retinal thickness map and treatment planning among retina specialists. Methods. Thirty-nine eyes with diabetic or branch retinal vein occlusion-related ME undergoing navigated MLP with ...

Glaucoma is a disease of the optic nerve that threatens the eyesight of the patients and is one of the leading causes of blindness. Because healing of died retinal nerve fibers is not possible early detection and prevention is essential. Robust, automated mass-screening will help to extend the symptom-free life of affected patients. We devised a novel, automated glaucoma classification system t...

INTRODUCTION Advances in MRI technologies have made it possible to achieve multilayer resolution of the thin retina of only 276 micron thick (1). In rodent and cat retinas, three to seven MRI-resolved anatomical layers have been reported depending on whether contrast agent was used (1-3). Contrast-enhanced MRI following intravenously injection of Gd-DTPA revealed two unique (retinal and choroid...

This study presents a segmentation method for the blood vessels and provides disease diagnosis in individuals based on retinal images. Blood vessel images of retina is very challenging medical analysis diagnosis. It an essential tool wide range diagnoses. After binary image improvement operations, resulting are processed features used as feature vectors to categorize diagnose type available. To...

Eye growth and myopia development are controlled by the retina. What properties of the image tell the retina how the eye should grow? A recent study has shown that, in chickens, fine details are necessary to prevent the development of myopia. Should we carefully avoid any defocus to avoid becoming myopic?

This paper presents a comparison relating two different architectures dedicated for a vision system on chip. The first one implements a logarithmic CMOS imager and a microprocessor. The second involves the same processor with a CMOS retina which implements hardware operators and analog microprocessors. We have modeled two vision systems. The comparison is related to image processing speed, proc...

This paper presents the first results of my PhD thesis, which addresses the problem dominant points detection for motion analysis on programmable retina. The goal of this research is to develop new algorithmical concepts to implement efficient image processing tools over the massively parallel cellular array of processors of the programmable retina, in order to perform effective motion analysis...

With the ability of MATLAB to run in the cloud environment the authors analyse a retinal image efficiently. A quick and on-the-fly image processing is the cause for leveraging the ability of Cloud with the classic computing power of MATLAB. This cloud-based image processing has significantly saved on the cost of procuring resources and it has processed an image in a few seconds. This revolution...
