Retinal vascular imaging: a new tool in microvascular disease research.
The microcirculation is relatively inaccessible to direct visualization and investigation. Recent methods have been developed which use advanced retinal photographic imaging techniques and computer-assisted image analysis to characterize, measure and quantify subtle variations and abnormalities in the retinal vasculature. These quantitative and qualitative assessments demonstrate a close associ...

متن کاملRetinal Vascular Occlusions
The hallmark of clinical presentation in the retinal occlusive disease is painless loss of vision, which can be asymptomatic, gradual with only mildly reduced visual acuity, or sudden and reduced to counting fingers depending on the extent of the irrigation area of the affected vessel. The clinical presentation aids in distinguishing the type of the occlusion, which may be classified according ...
متن کاملUncommon retinal vascular anomalies.
STANDARD works on the anatomy of retinal blood vessels (Leber, 1915; Wolff, 1954; Michaelson, 1954; Ballantyne and Michaelson, 1962) state that the four principal divisions of the central retinal artery and vein proceed to and from their respective quadrants, pursuing a sinuous course and branching dichotomously. This paper describes three types of uncommon retinal vascular anomaly with a unila...
متن کاملAcute retinal vascular proliferation.
THs condition is described under its usual title retinitis proliferans by Duke-Elder (1940), who states that it depends essentially on two factors; the presence of a haemorrhage on the inner aspect of the retina and a sufficient degree of irritation to stimulate a fibrous reaction. The aetiology is divided into three main groups: (A) Trauma. (B) Chronic infective conditions, e.g. syphilis, tube...
