Acute 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...
متن کاملAcute Variations in Retinal Vascular Oxygen Content in a Rabbit Model of Retinal Venous Occlusion
PURPOSE To study the variation in intravascular oxygen saturation (oximetry) during an acute retinal vein occlusion (RVO) using hyperspectral computed tomographic spectroscopy based oximetry measurements. METHODS Thirty rabbits were dilated and anesthetized for experiments. Baseline oximetry measurements were made using a custom-made hyperspectral computed tomographic imaging spectrometer cou...
متن کاملOptic neuropathy and central retinal vascular obstruction as initial manifestations of acute retinal necrosis.
BACKGROUND The purpose of this brief communication is to alert ophthalmologists that optic neuropathy may herald acute retinal necrosis (ARN). CASE A previously healthy 54-year-old man exhibited optic neuropathy as an initial presentation of ARN, 8 weeks after varicella-zoster dermatitis. OBSERVATIONS Central retinal vascular obstruction developed subsequently in his left eye. Later, the cl...
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...
