OBJECTIVES To describe the 15-year incidence of retinal vein occlusion (central retinal vein occlusion and branch retinal vein occlusion) and associated risk factors. METHODS A population-based study where branch retinal vein occlusion and central retinal vein occlusion were detected at baseline (n = 4068, 1988-1990) and three 5-year follow-up examinations by grading 30 degrees color fundus p...

Retinal images play vital role in several applications such as disease diagnosis and human recognition. They also play a major role in early detection of diabetics by comparing the states of the retinal blood vessels. The detection of blood vessels from the retinal images is a tedious process. In this work a new algorithm to detect the blood vessels effectively has been proposed. Initially enha...

BACKGROUND There are some cases that reported central retinal vein occlusion accompanied by ciliary artery occlusion, however, combined branch retinal artery and vein occlusion is a rare condition that has been infrequently reported. We describe in this report one case of retinal vein occlusion and branch retinal artery occlusion occurring simultaneously. CASE PRESENTATION A 50 year-old woman...

Retinal vessel segmentation is critical in detecting retinal blood vessels for a variety of eye disorders, and consistent computerized method required automatic disorder screening. Many methods are implemented, but these only yielded accuracy lack good sensitivity due to the coherence segmentation. Another main factor low proper technique handle low-varying contrast problem. In this study, we p...

a 41-year-old man was referred with a complaint of visual loss in his left eye and his best corrected visual acuity was 20/80. slit lamp examination showed arborizing conjunctival vessels and dry eye. fundus examination and fluorescein angiography revealed a non-ischemic central retinal vein occlusion. cardiovascular, rheumatologic, and hematologic work up showed no abnormal findings. an ascert...

Percutaneous coronary intervention (PCI) of stumpless chronic total occlusion (CTO) lesions with a side branch stemming from the occlusion have a significantly lower treatment success rate because physicians cannot identify an accurate entry point with only conventional angiographic images. An intravascular ultrasonography (IVUS)-guided wiring technique might be useful for the penetration of st...

BACKGROUND AND PURPOSE The purpose of this study was to evaluate whether bright vessel appearance on arterial spin labeling (ASL) MRI can help localize arterial occlusion sites in patients with acute ischemic stroke. METHODS Patients who underwent MRI for suspected acute ischemic stroke, as identified by an area of restricted diffusion, were included. All images were visually analyzed for the...

Central Retinal Artery Occlusion (CRAO) is the partial or complete blockage of central retinal artery presenting as acute painless monocular vision loss with increased risk in those cardiovascular disease. Diagnosis CRAO requires a dilated fundoscopic exam performed by an Ophthalmologist. In resource limited hospitals, access to these expertise and resources may be difficult.
